Gloves for working with an angle grinder
Working safely with an angle grinder: rules
Before starting work, be sure to wear safety glasses and a mask that will protect you from sparks.
You also need appropriate uniforms, it can be tight trousers and a jacket. These are 3 basic rules that you should definitely adhere to when working with this quite a safe tool.
Otherwise, sparks and shards of bare metal will fly directly into your eyes, and fall on your hands and feet. Thus, numerous burns and wounds can be earned. Therefore, you should not get to work without uniforms.
Important! The mask must be covered so that sparks and debris cannot enter your face. It is also good if a mesh is fixed on the mask, since the blows of small debris can be very strong, that the reinforced protection may not withstand blows.
The safety cover must be thick and made of dense materials. This is the first barrier that stands between you and the spinning circle at high speed. There are cases when at speed the circle collapses and damaged pieces fly into a person.
By using the cover, cuts and other injuries to the face and body can be avoided. Despite the fact that it is difficult and inconvenient to work in this special uniform, but it is safe, it will be able to protect the operator from various kinds of injuries and protect him from the most unpleasant consequences.
safety rules for working with an angle grinder, which must not be violated
This traumatic tool cannot be replaced with anything during construction and repair work.
What is the perfect protective clothing for angle grinding? (English)
Unassembled, tired and absent-minded people cannot work with an angle grinder. Today, there are several elementary rules that should be followed while working with this tool.
Additional means of protection
In addition to these protective items, the operator will need gloves or mittens when working with the angle grinder.
Regardless of the weather, be sure to wear them to protect your hands from burns and cuts. Since it is these parts of the body that are next to the instrument and at any time a spark, abrasive particles or metal burning fragments can fall on the upper limbs.
Leather gloves are best suited to protect hands, cotton gloves can quickly deteriorate and do not protect the wearer from burns. It’s worth making it a rule!
Important! Clothes should not be very wide and well tucked in.
Correct use of the tool
Important! If there are potholes, chips and cracks on the circle, it cannot be used in work. This will result in kickback and permanent destruction of the part. It is at this moment that a dangerous situation can arise, during which the operator may be injured.
- Hold the angle grinder with 2 hands. This is the main rule in work. During work, the position of the body must be stable so that the operator does not lose balance, therefore, it is strictly forbidden to work with such a tool in a drunk state.
- Also, when working, you should take care of the power cord, it should be located to the side so that the rotating circle does not cut it, and also a short circuit does not occur.
- Most often this rule is violated. during cutting, the main thing is to ensure the correct position of the tool. the line of the cut should pass by the operator and not rest against him. Also, when cutting, do not put too much pressure on the angle grinder.
You are now familiar with all safety rules when working with an angle grinder.

Good day. In a previous post about a brake upgrade, someone chided me for working without gloves. I use gloves only in the cold season, but even at minus 20 when working with a drill or an angle grinder, I always take them off. Today a neighbor in the garage accidentally demonstrated why I am doing this
angle grinder Makita 9565cv. 1400 watts, with rev support. It’s good that it has protection against biting, otherwise it all ended not with scratches but with much more serious injuries
Shl. And I also have one superstition, after receiving even a small scratch, you have to sacrifice the tool, clean, lubricate, change brushes))

There was a similar situation, only jeans were wound that did not hang like sleeves. Wound it on the same brush head as in Maxim’s article. The jeans were old and not very strong, so at the moment of contact (I don’t know how it happened with my colleague) a piece of jeans was torn out (not completely torn off from the jeans) and wound up. The angle grinder pushed against the groin and stopped, because it had already wound a piece from the knee to the groin to that place. The angle grinder twitched and tried to wriggle out and rewind further I managed to pull the plug from the socket. Everything from the knee to the groin area was torn more feasibly than the hand in the photo, but the pisun did not hurt. ahahahah
That’s right. Do not work with rotating objects in gloves and with clothes with long sleeves. So that the shaft does not wind, roll up the sleeve)))))
Most likely, everyone will remain unconvinced. I’m not going to convince anyone. I was talking about gloves with a rubberized layer, like these: enerplus.ru/upload/resize.cc7cec84261727b624827.jpg Once my wire attachment fell apart, and it was only thanks to such gloves that my hand did not look like a porcupine. And now about this post. Yes, in such rag gloves, working with an angle grinder is even more dangerous. in addition to winding on once or twice, you won’t be able to squeeze the machine in your hands too much, it slips. And in general, if the angle grinder bites, twitches during operation, if it vibrates, then either you are doing something wrong, or the nozzle is worn out / unevenly worn this applies to both discs and various brushes, crowns, circles, etc.) My health is dearer to me, I’d rather not be stingy and buy myself gloves for 150 rubles and a protective mask, take a new disc or brush, than then I will observe sewn n ogu / arm and ripped pants / sleeve.
it seems like on the TP with this kind of tool, you always need to work without gloves and only with a protective shield installed
If you just look at at least pictures on the Internet about working with an angle grinder, then 95% of them you will see that people work in overalls with buttoned sleeves, leggings or gloves, and sparks fly at their feet, and not on my own. And if someone in shorts and flip-flops decided to “swiftly” to swallow something, then they are simply naive, believing that they will be carried over and nothing will happen, “I did it a hundred times.” They did it a hundred times, but for the one hundred and first the hand or something else will tremble, and there will always be work for the staff of the first-aid post because of such arrogant.
but tell me about the Kevlar gloves (I saw them on Ali, they look like calchuzhny ones) how they work?
well, if I understood correctly, then there should not be a sickly bite, not a glove
the principle is clear, but in the video the spindle was bitten hard, and the angle grinder I think will not replace the glove, as well as the hand / leg (I will not wish TTT to anyone) It seems to me protection so that the disc does not jam and break.
First of all, you cannot work with an angle grinder with gloves. Secondly, everything here is even more pragmatic, I think it was. The part must be fixed and held by the angle grinder with both hands. And such as in the photo usually happens when the angle grinder is held with one hand and the other part. we expect the result))
IMHO, the wrong choice of means of protection. Split leather or thick leather gloves / mittens should be worn. They do not twist into the tool, but cover the skin of the hard worker)
Due to the density. it will break through, or rather cut off the upper part, give a signal to the fact that the hands are no longer where they should be
The main types of grinders
This useful and practically universal power tool can not only saw, cut, but also grind the surface with emery wheels, clean rust with metal brushes and, in the presence of a special diamond circle, gently cut glass.
But not every model of angle grinder has a wide range of possibilities. And technical characteristics, such as power, rpm, recommended disc diameter and the list of possible operations, vary.
In addition, all angle grinders on the power tool market can be divided into the following categories in terms of operating time and endurance:
- For domestic use. this type involves the use of purely at home to perform simple tasks. The operating time of such models is up to 40 minutes.
- For professional use. this category of power tool is designed for a daily load of 3-4 hours. Similar models are used by masters who perform “turnkey repairs” and other types of repair work.
- Industrial. machines, it’s even embarrassing to call them simply “grinders”, designed for continuous use by the operator of an angle grinder all day long.
If the first two types are common among the population, then the latter are used exclusively in large enterprises working with serious objects. And to the employee applying for the position of the operator, increased requirements are imposed.
In particular, knowledge of the structure of a power tool, the principle of its operation, technology for performing work with its help and knowledge and observance of the rules of individual safety.
In addition, the devices can be classified according to the type of power supply: mains-dependent and rechargeable. And also divided into groups by cost and other criteria.
How to work with an angle grinder: safety measures instruction manual
Planning to use a power tool while doing home repairs, but don’t know how to use an angle grinder correctly to avoid injury? Agree, it would be unreasonable to unknowingly break the disk in the first minutes or, even worse, injure yourself.
Angle grinder VS gloves
Or have you just decided to acquire a power tool and are studying the rules of its operation in advance? In this case, pay attention to the products of well-known manufacturers with a good reputation, realizing really high-quality devices of excellent assembly with a long-term guarantee.
After all, it is safer to work with a reliable tool. One of the excellent options is the products of the Bosch, DeWALT, Makita brand, as well as the Metabo angle grinder sold in the myo network in a wide range. We will consider in detail the rules of operation and the main mistakes when working with this type of power tool in our article.
The material, in addition to recommendations for using the angle grinder, contains visual photos on working with an angle grinder and useful video tips from experienced users. Having familiarized yourself with the latter and, observing the rules of personal safety, you will be able to cope with the slashing of a concrete wall, cutting tiles or bricks on your own, without involving specialists for these tasks.
Types and features of using an angle grinder
The popularly known angle grinder is nothing more than an angle grinder. This power tool, according to ordinary people, is a must for every owner in the slightest degree respecting himself.
It is not surprising, because in addition to grinding, the device is able to perform high-quality cutting of various kinds of materials, from simple wood to metal corners and fittings.
Most often in everyday life, this tool is used not for grinding operations, but specifically for cutting materials.
The subtleties of operating a power tool
Before learning how to make an even cut, you need to figure out how to use a household angle grinder correctly so as not to damage yourself.
But you should not ignore the instructions, because the angle grinder is not only a useful tool in the household. the angle grinder is also extremely traumatic in the hands of an inexperienced operator.
There are frequent cases of serious injuries to the face, limbs, torso during careless handling of the device. Even more often, eyes suffer from scale, sparks and other foreign objects if they are not properly protected.
over, no one is insured against an accident. even experienced users who have been working for 20-25 years with an angle grinder, by coincidence, turn out to be visitors to the emergency room.
Therefore, it is important, first of all, to protect yourself with personal / personal protective equipment (PPE).
Each type of work involves its own type of gloves, which will be more comfortable and safer.
Cotton and knitwear with PVC inserts are capable of protecting against mechanical damage. Combined options with dotted splashes make the gloves durable and elastic at the same time. Such types will be convenient for working with glass, therefore, they will be useful to the glazier.
For precise work, it is fabric specimens that are best suited, and rather thin ones.
Latex gloves will help prevent chemical burns and exposure to harmful substances. For example, they can be used when working with liquid nitrogen, chemical reagents in various laboratories. In addition, a special coating provides them with an anti-slip effect. Therefore, they are quite suitable for working with a rope.
Nitrile gloves will protect you from hot surfaces and minor injuries. The reusable nitrile-coated cotton base is particularly durable and heat-shielding. But there are also very thin disposable gloves. They allow you to work even with paper, since you hardly feel it on your hands.
Neoprene products will protect against moisture, chemicals, oils. Suitable for mechanics. Gloves are durable and wear resistant.
Split leather gloves are made of leather and are considered to be a product of increased strength. Withstand both high and low temperatures. Suitable for working with metal, welding. But even in cold conditions, they are irreplaceable, especially reinforced with a warm lining. In such gloves, you can not only work, but also go skiing, hiking, and work on the street. For the same purpose, suede gloves are also suitable.
Polyurethanes are used in various fields because they provide good protection and at the same time the sensitivity of the hands. They are equally good for work in a car service, and for cutting large batches of fish.
Polymer coated gloves provide protection and will be indispensable in the work of an installer, builder.
But for installation work with an angle grinder, other types may also be suitable, for example, with PVC inserts.
The rag varieties are suitable for repair work in the house, as well as in the garden. Many options can be used in different conditions, and everyone chooses the best for himself.
Features of work gloves
In any production, most of the processes are mechanized, but at the same time there are many works that have to be done by hand, and this requires gloves. The features of gloves differ depending on what actions they are used for.
Work gloves are designed to protect your hands not only during the work process, but also during gardening or household work.
The main requirements for such products are as follows:
- they must be strong so that in the event of heavy loads, friction or other influences, their integrity is not compromised;
- density also plays an important role, since in many jobs there is a risk of injuring your hands. scratching, hitting, piercing, burning;
- they should be comfortable. no stiffness of movement or discomfort, in certain cases the fabric should be breathable so that your hands do not sweat and do not get wet.
Criterias of choice
To get the best option, you need to take into account certain factors.
- The type of activity in which the gloves will be used. For work that requires sensitivity of the hands, you need to use thin options; work on the construction site will be more efficient if you use polymer-coated gloves. Split options are more relevant for work in the cold.
- The degree of protection that certain products can provide to avoid punctures, cuts and other damage. When working with chemicals, for example, it is better to use neoprene products.
- Air temperature. On a hot day outside, light rag options are suitable, in cold weather. warmed.
- One of the important indicators is size. Gloves should fit perfectly on your hands to ensure complete comfort during work and other activities. If they are small, stiffness and inconvenience are provided. If the size is large, it is not possible to hold objects well in your hands, which can violate safety precautions.
Rules for working with an angle grinder
If working with a knife, hacksaw, or ax requires a high concentration of attention and little work skills, then when processing parts with a power tool due to inattention and non-observance of certain rules. the likelihood of injury will increase dramatically.
When performing work with power tools, you need to know and strictly follow all the rules and instructions of operating documents, study the techniques and methods of work that will exclude tool breakage and possible injury to the operator. The correct use of any type of power tool implies the accurate and rigorous implementation of simple techniques, possibly stopping the processing process a little, but at the same time preventing its dangerous operation and disastrous consequences.
Correct connection of the power tool to the mains, the duration of use and the degree of stress on its cutting parts, the use of guards, attachments and other provisions, the observance of which can eliminate or drastically reduce the risk of injury. Currently, all manufacturers complete their handheld household and professional power tools with special protective devices and detailed operating instructions.
In this article, we will consider in detail all the rules for the use of grinders (angle grinders) and abrasive discs.
The angle grinder must be connected to a mains voltage that corresponds to the voltage indicated on the type plate.
To ensure your safety, the following safety rules must be observed:
- Before using the angle grinder, make sure it is switched off and unplugged from the mains.
- Do not use an angle grinder without a special protective cover.
- Calculate cutting and grinding wheels at speeds not lower than those indicated on the tool plate. Grinding discs used with an angle grinder must be made on a reinforced fiberglass base.
- Before starting work, be sure to check the circle for all kinds of damage, cracks, deformations. If such damage is found, the damaged wheel should be replaced immediately.
- Use the flanges specified for this machine.
- Protect the spindle, lock nut and flanges (especially the mounting surface) from damage, as damage will lead to wheel failure.
- Do not touch rotating parts of the instrument.
- Before turning on the angle grinder, you need to make sure that the wheel does not touch the surface of the workpiece.
In order to remove the circle, you must repeat the above procedure in reverse order.
Before connecting the angle grinder to the mains, you need to check if the start switch is working properly and if it returns to the “Off” position after releasing it.
To turn on the tool, press the start switch. To turn it off, the machine must be released. For continuous operation, you must press the start switch and then the lock button; to switch off the angle grinder, push the start switch all the way down and release.
- After completing the work, you need to turn off the tool wait until the disc has completely stopped and only after that you can put the angle grinder.
- Hold the angle grinder firmly with your hands.
- At the very moment of the running-in of the disc, the grinder must not be moved in the B direction, because this leads to the plunge into the workpiece of an un-worn disc. Once the disc has run-in, the tool can be moved in both directions.
- Do not apply force to the machine. Its weight creates sufficient pressure on the workpiece. Excessive force and pressure will rupture the disc and damage the angle grinder.
- Prolonged use of damaged discs will rupture the disc and risk serious injury.
Carbon brush wear is when the rubber insulating tongue inside the carbon brush touches the manifold and causes the angle grinder to stop automatically. If this happens, then you need to replace the brushes. The brushes should be replaced in pairs.
Abrasive discs are produced with a diameter of 115.230 mm, thickness 1.2. 6 mm and each disc is specifically designed for an angle grinder with a specific power. To process a certain material, a specific disc is used, which is designated not only by an inscription, but also by markings of different colors. Discs are found in different designs, that is: with completely flat and uniform abrasive surfaces, with the presence of central metal inserts for attaching it to the spindle of an angle grinder.
It must definitely correspond to the spindle diameter of the angle grinder. In the event of a discrepancy, even if you tighten it strongly, this disc will create an imbalance when rotating and gaining revolutions, as a result of which the angle grinder will simply break out of your hands or, upon contact with metal, will fly into pieces.
In order to prevent chipping during production, the abrasive discs are reinforced on both sides with a special fiber, which is determined by the specific type of surface. Each disc for an angle grinder has a mandatory inscription (marking) that notifies you of the maximum speed that the disc can withstand (usually 80m per second).
A common violation of safety and operating rules is the use of abrasive or diamond discs of a larger diameter, which excludes the installation of a special casing to protect against sparks and particles of the abrasive metal being processed. In such cases, the risk of injury increases dramatically.

Personal protective equipment for working with power tools
When purchasing one or another hand-held power tool, how many of you, dear readers, study in detail all sections of the attached instructions? I think not. Usually, reading it is limited to familiarization with the technical characteristics and how to get IT to work. Such negligence can have absolutely irreparable consequences. And it is on this that we would like to dwell in more detail, and specifically on the need for personal protective equipment when working with various power tools.
Despite the fact that manufacturers are trying their best to secure the tool supplied to the modern market, it still remains quite traumatic.
A threat to life and health is, first of all, electricity itself, working attachments (drills, cutting and grinding discs, saws, knives, etc.) that work at great speed, their flying fragments, accidental uncontrolled emissions of chips, shavings and crumbs of the processed material, dust, noise and vibration.
Today there are a huge number of different means of protection that allow you to preserve hearing, vision, protect all parts of the body from mechanical and thermal injuries. Perhaps, when using the tool in everyday life, many of them will seem superfluous, but for professionals they are simply necessary.
The modern range of goggles is large enough. They vary in material of manufacture and shape. To work with power tools. angle grinders, circular saws, planers, etc glasses with transparent glasses are used. They consist of a body in which glasses are directly attached, and temples. A headband can also be used as a fixing element.
To protect against small solid particles flying from the front and from the side, you can limit yourself to open glasses. In case of possible multidirectional emission of solid particles, closed glasses with direct ventilation are preferable. With a large formation of dust, which is typical, for example, when working with grinding machines, or splashing non-aggressive liquids (for example, when wet grinding), closed glasses with indirect ventilation are the best option.
Considering the possible impact force of traumatic particles, the speed of which can be 45 m / s and more, it is better to pay attention to glasses with glasses made of special polycarbonate. They are highly durable and have little abrasion with proper care.
Safety goggles are tailored to the nature of the job to be done and the ability to customize them for a secure fit on the head At the same time, there are models that can be used over corrective glasses.
To prevent the glasses from fogging up, you can treat them with special compounds, or you can do with improvised means. rub the inner surface of the glasses with baby or glycerin soap and polish it with velvet.
Face shields are more practical, since they protect not only the eyes, but also the skin of the face and neck from mechanical damage.
For working with power tools, shields with a head mount and shields with a helmet attachment (of course, if it is supposed to be worn), with movable or fixed glass holders, are most in demand. Such masks are made of durable polycarbonate glass, including three-layer glass, and may contain additional steel mesh.
For the most part, power tools designed for work accompanied by the formation of a large amount of dust are equipped with special dust collectors or equipped with nozzles for connecting to an industrial vacuum cleaner. But, for example, in drills, rotary hammers and jackhammers, built-in dust extraction systems are quite rare, and in this case, the user must take care of respiratory protection on his own.
The simplest means of protection in this case can serve as disposable gauze respirators. They are not burdensome when worn for a long time, but, alas, they are not always effective enough. If you often have to deal with this kind of work, it is better to purchase a professional mask with a replaceable filter. At the same time, full-face masks do not need to be supplemented with goggles. Having spent one time to purchase such an accessory, you will for a long time get rid of the need to swallow dust when cutting and drilling concrete, during intensive work on sawing wood, etc.
It is known that absolutely silent power tools simply do not exist. During operation, they create the most unpleasant shock noises for hearing.
Practice has proven that repeated prolonged exposure to noise levels of 70-90 dB can cause significant weakening or even loss of hearing, and the instructions for most power tools indicate a possible level of 85 dB. This means that during intensive work, personal hearing protection must be used. headphones or earplugs. The choice of both is extremely extensive.
Earplugs can be disposable or reusable, with a string or rigid rim. As for full headphones, you can find electronic ones with the ability to adjust the level of external sounds. suppress loud and amplify weak.
Do you prefer listening to music while working? And this is not a problem, since there are headphones with a built-in stereo receiver. Communication headphones, while absorbing loud noises, allow you to hear normal speech at the same time.
Even if you do not work with welding, but are only going to cut steel with an angle grinder, it is worth getting special clothing made of fabric impregnated with a flame retardant compound. Hot sparks generated during the cutting process scatter within a radius of up to 2 meters, burning and igniting easily combustible objects. Oiled overalls that are not designed for this can cause severe burns.
For the safety of the user, chain saws are equipped with a number of protective functions and devices, however, when working with them is an integral part of the professional activity, it makes sense to purchase special trousers containing inlays made of durable fiber material in the legs. When throwing back the saw, the most likely affected area is the knee-lower leg. After a tear in the top layer of fabric, the fibers wrap around the headset, causing the saw to jam, providing additional protection against injury.
Hands in direct contact with a power tool need protection, perhaps even more than all other parts of the body. They are the first to take on scalding sparks, prickly splinters and blows. A wide range of specialized gloves and mittens are available to protect the hands, depending on the type of work involved. When purchasing the latter, it is worth remembering that thread gloves are unacceptable for working with a tool, the working nozzle of which makes rotational movements. And these are angle grinders, circular saws, chain saws, drills, hammer drills, etc. Universal for working with almost any power tool are light leather split leather gaiters, which provide reliable protection against thermal and physical damage to the hands and wrists. However, they are not comfortable enough in summer. For work in heated rooms and in the warm season, it is better to get fabric gloves with leather inserts.
Work shoes should be as comfortable and durable as possible, as well as exclude all kinds of thermal and mechanical injuries. There are specialized safety shoes for welders, turners, riggers, etc. In the first case, Accent is made for heat resistance, in the second. to prevent the ingress of sharp shavings, in the third. to exclude self-harm as a result of falling heavy objects, etc. Which footwear is right for you depends on the type of envisaged activity. For example, when making openings with an angle grinder, protect your feet with steel-toed shoes, and if you are going to cut metal, look for a shoe for welders. In any case, the shoes should be non-slip, with an impenetrable sole (you never know what will fall under the foot), a durable upper and preferably non-conductive.
In terms of protection against electric shock, it is preferable to have electrical insulating mats at a stationary place of work, and it is also necessary to monitor the integrity of the power cords. In addition, remember that double-insulated power tools must not be connected to extra-grounded sockets, while tools with a grounding pin on the plug (Protection Class 1) must only be connected to grounded outlets. When using drills as mixers for mixing various mixtures and solutions, you should be warned against possible electric shock using dielectric gloves.
And, of course, do not forget about the first-aid kit: in which case, you should always have dressing materials, pain relievers, hemostatic, disinfectants and anti-shock agents at hand.
And I would like to end with what we started with. with instructions. Its careful study and strict implementation of all the requirements and recommendations set forth in it, taking into account the information provided, will make working with any power tool as safe as possible.
The site is not a public offer determined by the provisions of Article 437 (2) of the Civil Code of the Russian Federation.
How to hold an angle grinder while working
The correct grip of the angle grinder will largely ensure competent and safe work with the tool:
- The handles of the sander must be firmly gripped with both hands, without shifting its center of gravity to either one. With a secure grip, even in the event of a kickback, there will not be a serious displacement of the tool, and even more so it will not be pulled out of the hands.
- The power cord must be kept away from the rotating blade: catching it will create a short circuit and a sudden stop of the tool, possibly resulting in kickback.
- the cutting line should be positioned in such a way that the angle grinder goes to the master, moreover, the person should not be in the plane of the possible expansion of the disc. In this case, the direction of sparks is possible both away from the master and under him. everyone decides for himself. There are no options for left-handers. when you grip an angle grinder, the sparks will go “under yourself” in the only convenient way for a left-hander. And an obligatory rule. there should always be a bucket of water nearby to extinguish a fire possible from sparks.
- It is forbidden to put the tool anywhere until the rotation of the working disc is completely stopped, otherwise objects and planes not intended for processing may be caught.
- If you need to move the angle grinder from one place of work to another, you should turn it off, since any careless movement of the master (tripped, swayed, fell) can lead to unpleasant consequences: injuries, capture of foreign objects, clothes, etc.
- The working disk heats up significantly during work, and, of course, you should not touch it until it cools completely.
Before proceeding with direct work with the instrument, some preliminary preparations should be made:
- You should not work with any power tool (not only with an angle grinder) being unhealthy, tired or in a state of alcoholic intoxication. the loss of clear control over the body leads to negligence in actions, lack of the required reaction speed and uncoordinated movements.
- Indispensable components of safe work with an angle grinder are closed safety glasses (preferably reinforced) to reliably protect the eyes from the ingress of sparks or scale flying along an unpredictable trajectory, as well as a protective cover that ensures that no fragments of the processed material and sparks fall into the working material.
- Always wear gloves or work gloves made of thick leather on your hands.
- Work clothes should not be wide and at the same time should not restrict movement. Its parts should be carefully tucked in and no hanging or dangling elements: strings, fringes, etc., which could tighten under the moving disc of the instrument, should be avoided. When working with stony materials without organized stone dust extraction, a dust mask should be used to avoid respiratory problems.
- The tool must be fully functional, do not use a deformed or damaged working disc, the use of which could cause kickback.
Angle Grinder Safety
“Angle grinder” is a simplified name for an angle grinder that has long become popular. It is used everywhere: in construction, and in agriculture, and in private household work. Designed for grinding and cleaning surfaces of various kinds, for cutting metals of any thickness, stones and other materials. This power tool got its unofficial name thanks to the country of origin. Bulgaria.
The working element of the angle grinder is a special disc, the configuration of which is selected depending on the material being processed. At the slightest careless movement of the master, a nozzle disk moving with a huge rotation speed can lead to at least wounds or cuts, and in more serious cases. to serious injuries.
Inappropriate safety precautions make the angle grinder an extremely dangerous tool, therefore, the rules specified for working with it must always be strictly followed.
The most common and dangerous moment of working with an angle grinder is the occurrence of kickback, which is characterized by an instant and very sharp throw of the tool towards the operator. The force of impact is so great that it is simply impossible to hold an angle grinder in your hands. this is especially dangerous if the work is carried out at head level. Kickback injuries can be severe enough to be fatal.
The kickback can be caused by the use of a non-working (deformed or damaged) working disc and / or its jamming in the material. Very often, the kickback occurs at the final stage of the cut, when it remains only to finish the last layer of material that connects the cut parts. In this case, it is recommended not to finish the cut from the same side, but to execute it on the other.
Safety precautions to prevent the occurrence of a kickback or at least minimize its consequences for a person contains several simple rules:
- It is unacceptable to use accessories not intended for the angle grinder:
- a circle with a larger diameter, since to install it, you will have to remove the protective cover and, during use, there will be an excess of the linear speed of the cutting edge;
- a saw blade completely unsuitable for the rotation speed of an angle grinder. a hard-alloy soldering that has flown off from his tooth at a cosmic speed can become a fatal bullet for a careless master.
- The operator must stand firmly with both feet on a firm and level surface to resist the impact energy.
- Be extremely careful when handling sharp edges, material edges, and any corners. It is necessary to be prepared for a possible kickback of the angle grinder and the body to move away from the intended place of defeat as a result of a return impact.
- If the working disc is stuck, turn off the angle grinder and remove the cutting disc from the cut.
Safety precautions and understanding of the principles of working with an angle grinder guarantees high-quality performance of the tasks set without any injury or harm to human health.
When working with an angle grinder for long periods of time, be sure to use a respirator. You can ordinary
Or use a half mask with a charcoal filter
Stop when breaking and clamping a disc.
Some sanders have a system that detects a broken disc and shuts down. Also, such an angle grinder will turn off if the disc starts to clamp. The machine does not have to be pulled out and the risk that the disc will fly apart is minimized.
Clothing should protect against flying sparks. Even if it is very hot, it is worth putting on overalls while working. Clothes should not be made of “plastic”, otherwise they may melt or even catch fire. All the buttons are buttoned, nothing hangs or dangles from the clothes. Because it is unsafe, especially when working with large grinders.
Turning off the brushes when the power is turned off.
Many professional grinders are equipped with a system for turning off the brushes in the event of a sudden power outage. For example, if the power was turned off during operation, the angle grinder will not start working when it is turned on. It must be turned off and on again. It so happens that during operation the power is cut off, and the master, having forgotten to turn off the angle grinder, goes to look for an open circuit or the reason for the shutdown. If the electricity suddenly turns on, from the absence of the master, the angle grinder with such a system will not turn on and will not start sawing everything around it.
What you need to know about an angle grinder
The angle grinder, or, as we often call it, the angle grinder, came to us, oddly enough, from Bulgaria in the 1970s.
In general, an angle grinder (or grinders) is a rather broad concept. But I will tell you about the features of working with an angle grinder from the point of view of a plumber. I will share examples from my experience. And I will say a few words about safety when working with the tool.
For myself, I have divided the angle grinder into three types: small, medium and large. (We do not take into account very large ones)
The best combination, in my opinion, is to have a large and small angle grinder in operation.
A small angle grinder is very convenient to crawl into tight spaces, it is lighter and safer (easier to hold) a medium-sized angle grinder is the very alternative when there is no big one, and the small one can no longer be finished. Well, and the large one is designed for cutting large pipes (it has a large cutting depth). Those. has a disc of a larger diameter and, accordingly, a cut is obtained deeper, which is important when working with large diameters.
Once or twice for household needs or every day (professional need)? If you need an angle grinder for a one-time job or you buy one just in case, then buy a household one. It is inexpensive, and if you have to work all day, just let it cool down every half hour.
If for household needs you want a more reliable angle grinder (so as not to overheat), then I recommend taking a small angle grinder at the price of 3-4 cheap ones. Large cutting machines for household purposes are rarely needed. If you work with pipes, then a small angle grinder can cut pipes up to a diameter of 50 mm (with a 125 mm disc). When buying inexpensive grinders, you must keep in mind that it will not be able to serve for a long time, because it is made of cheaper materials. The first thing that usually “flies” in household grinders during intensive use is the gearbox bearings.
Handle attachment options.
There are machines with a fixed main handle and an additional handle that can be unscrewed. And there are grinders, where this very handle can be screwed in from the other side or from above.
