Therefore, it is important, first of all, to protect yourself with personal / personal protective equipment (PPE).

The main types of grinders

This useful and almost universal power tool can not only saw, cut, but also grind the surface with emery wheels, clean rust with metal brushes and, if there is a special diamond circle, gently cut glass.

But not every model of angle grinder has a wide range of possibilities. And technical specifications, 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 household 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 tools 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 “angle 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 increased requirements are imposed on an employee applying for the position of an operator.

In particular, knowledge of the structure of a power tool, the principle of its functioning, technology for performing work with its help and knowledge and observance of the rules of individual safety.

In addition, devices can be classified according to the type of power supply: mains-dependent and rechargeable. And also divide into groups by cost and other criteria.

Individual protection means

During cutting, a sheaf of sparks flies, which can enter the eyes. For protection, wear glasses or a mask made of transparent plastic.

The sound of the angle grinder is irritating to the ear drums, to protect hearing, insert earplugs or wear construction headphones.

The angle grinder generates a lot of dust on time. To protect the respiratory system from dust, wear a respirator.

Heavy boots with iron inserts will protect your feet from falling metal parts. Shoes are tightly laced so that sparks and scale do not get inside.

What is an angle grinder for?

When you look at modern angle grinders, you will notice that they are able to cope with many tasks, including:

Polishing;
Grinding;
Cutting glass, tiles, stone, plywood, concrete, brick and metal.

A specific abrasive tool should be used for each type of work and material.

Rules and guidelines

After fastening the wheel, the tool should be started and checked in idle mode. Within 30 seconds, the equipment is run at maximum speed. If you have not noticed any extraneous sounds and vibrations, and the protective casing does not touch the disc, then you can start work.

Quite often, novice home craftsmen ask themselves how to work an angle grinder correctly. Before starting the manipulations, the operator himself should prepare, for this you need to wear:

The operator needs to remove all jewelry, such as watches and bracelets, because they can be wound around a circle. You should not start work if you are tired or in AL-KOH drunkenness. Eliminated the use of saw blades for wood when working with an angle grinder.

Basic rules for cutting

When cutting a workpiece, it is important to make sure that you follow the basic rules. The cutting line should pass by the person, but not rest against him. If the disc is seized, the jet propulsion of the equipment will bypass the operator. It is important to provide protection with a cover. It should be located between the employee and the circle.

There is no need to apply excessive pressure to the tool. The unit will be able to cope with tasks using its own weight. Whereas overloads will cause the circle to skew. The inclusion of the angle grinder when the disc is in the profile of the workpiece is excluded. You should start cutting the profile from the place where the cross-section is the smallest.

It is important to remember that a lot of dust will be generated when cutting tiles, concrete and stone. Respiratory organs should be protected from it. Some manufacturers produce hoods with a nozzle for a vacuum cleaner. You can also suppress dust with water, directing a jet into the cut. If you need to work on opening the wall, you must be prepared for the fact that reinforcement, pipe or cable can get under the circle. This will certainly cause kickback. Stay clear of the cutter line to avoid injury.

General advice for working with an angle grinder

You can familiarize yourself with this information by looking at the instructions on the disc or packaging.

Operational Safety Angle Grinder

Before starting the workflow, you must prepare the tool. For this, a circle is selected and installed. The motor has a certain power, it provides for the need to select a circle of certain sizes. The smaller the circle, the higher the rotation speed it can support. If the wheel is used incorrectly, it will cause wear on the equipment and deformation of the nozzles.

If you are thinking about the question of how to properly operate an angle grinder to avoid injury, then you should know that discs that are larger than those for which the unit is designed should not be installed on the tool. The attachments must not be deformed. If cracks or potholes appear on the circle, then get rid of them. Do not use those circles that have deviations from the original shape.

Outwardly, the angle grinder looks unpretentious, it has a cylindrical body, on one side of which there is a handle, and on the other, a mount for nozzles. It is the attachments that make this unit multifunctional. They are fixed to the spindle, while the discs are additionally secured with a clamping nut and flange. This measure is mandatory when working with the described tool.

Required tools

Understanding how to work properly with an angle grinder will help you to perform the planned work efficiently and protect your health, and sometimes life. An angle grinder is a tool that must not be neglected and instructions must not be ignored.

Angle grinder. What is this beast?

Angle grinder (angle grinder). This is the name of the tool that many people know as an angle grinder. The first models of this tool in the USSR began to be produced in Bulgaria at the “Eltos. Angle Grinder” enterprise. The first angle grinder was produced only as grinders, later the angle grinder became more functional and practically irreplaceable in construction and metalworking.

The outwardly angle grinder looks quite simple and unpretentious: a cylindrical body, on one side of which there is a handle, and on the other side there is a side handle (optional) and attachment for attachments. It is the attachments that make the angle grinder such a versatile tool. All attachments are attached to the spindle, and the discs are always additionally fixed by means of a flange and a clamping nut. This is a must when working with an angle grinder.

Modern angle grinders can cope with many tasks: sanding and polishing surfaces, cutting stone, tiles, glass, concrete, plywood, metal and brick, and if necessary, even a loaf of sausage can be cut into shape, the main thing is to choose the right attachment. It must be remembered that there is an abrasive tool for each separate type of work and material to be processed.

Replacement attachments for the angle grinder are represented by the following assortment:

Brushes. For cleaning and polishing surfaces. You can clean metal from rust or polish welds.
Circles. The use of circles depends on their composition. Some can cut metal, others only ceramics. All this can be found in the instructions on the packaging and on the disc itself.

Not only removable attachments are different, but also the angle grinder itself. They are household, professional and industrial. A household tool can be used no more than 40 minutes and not every day. A professional angle grinder can work for several hours every day, and an industrial one. A real workaholic. Can work almost tirelessly. Differences can also be found in the appearance of the tool: angle grinder with one handle, two handles and vibration-absorbing handles.

Safety precautions or how to properly operate an angle grinder

Before starting the work process, it is necessary to prepare the angle grinder: select and install the wheel. The power of the angle grinder motor requires certain wheel sizes. The smaller the circle in diameter, the greater the rotation speed it can withstand, and vice versa, the larger the disc, the fewer revolutions it can handle. Improper use can lead to rapid tool wear, deformation of tips and other undesirable consequences.

Deformed tips are not suitable for use in work. You should get rid of circles with cracks, potholes and other deviations from their normal shape. After the wheel is successfully secured, the angle grinder is checked in idle mode. It is necessary to plug the tool into the network and run it at maximum speed for one minute. If no unnecessary vibrations and sounds are heard, and the protective cover is not touched by the disc, then the tool is ready for use.

It is also necessary to prepare for work for the person himself who will operate the angle grinder. The angle grinder has a protective cover that is designed to keep the disc from sparks and debris if it explodes. But the cover will not provide complete protection against injury. Therefore, you should wear:

Protective mask or goggles;
Overalls;
Thick gloves;
Respirator.

You also need to remember a few prohibitions:

Do not leave jewelry (for example, a bracelet or watch) on the body that can be wound around a circle;
It is impossible to work, being in a state of fatigue or illness, a state of AL-Headache and drug intoxication;
Saw discs for wood can not be used for angle grinder;
Cannot be in the cutting plane;
Do not release the tool from your hands until the rotation stops completely;
Do not touch the equipment before it cools down after work;
Do not leave flammable objects in the work area: rags, ropes, fuel, solvents, etc.;
Don’t forget to keep a first aid kit nearby.

Securing parts is an important aspect of how to properly operate an angle grinder. Everything that is cut and processed must be securely fastened. The only exceptions are elements that, by their own weight, guarantee immobility (stones, slabs, etc.). The part can be clamped in a vice or you can use the help of a partner who will hold, for example, a pipe wrench or other workpiece. Correctly laid part should not have sagging in the kerf.

How to properly work an angle grinder to keep all fingers intact? How to cut an angle grinder correctly: requirements and recommendations

The angle grinder is on alert, the workplace is cleared of foreign things and people, the workpiece is securely attached and marked. This is exactly the moment when you can start working. The angle grinder should be held firmly and confidently with both hands. It must be taken so that in the event of a wheel jamming, the tool will not be pulled out of the hands, and in the case of a reverse impact, it will not lead to a strong displacement. Kickback is one of the most dangerous moments when working with an angle grinder. This is a sudden and sharp rejection of it as a result of the disk jamming in the workpiece.

The position of the body during work should be stable, you should stand so that sparks do not fly to your legs, clothes, and even more so to your face. The power cord of the angle grinder must be out of the reach of the rotating blade to prevent snagging. And if you need to move to another object, the tool should be turned off and drag the cord to a new safe position. You should also turn off the angle grinder if there is a power outage.

To the question: “How to cut an angle grinder correctly,” manufacturers unequivocally answer: “So that the direction of rotation of the disc and the movement of the tool itself coincide.” In this case, a jet of sparks will close the markings along which the cut is made, so this rule of operation is often ignored, but in vain. It is necessary to bring the disc into contact with the surface at full spindle revolutions so that the wheel does not jam.

Rules for cutting an angle grinder:

It is necessary that the line of the cut passes by the working person, and does not rest against him. And in the event of a jammed disc, the reactive movement of the tool will pass away from the operator.
The protective cover will provide protection if it is between the circle and the worker.
There is no need to press hard on the tool. The angle grinder will cope with the task under its own weight, and overloading will only lead to a skewed wheel.
You cannot turn on the angle grinder if the disc is located in the cut of the workpiece.
Cutting profiles must be started from the place with the smallest cross-section.
When cutting stone, concrete or tiles, a lot of dust is generated, which must be protected from the respiratory system and must be disposed of. There are special covers with a nozzle for a vacuum cleaner. You can also suppress dust with water by directing a jet of water into the cut.
When cutting walls, you must be prepared for the fact that a cable, pipe, fittings can get under the circle, which can lead to a reverse impact and therefore it is better to stay away from a possible mowing line of tool displacement.

The main types of grinders

But not every model of angle grinder has a wide range of possibilities. And technical specifications, such as power, rpm, recommended disc diameter and the list of possible operations, vary.

Therefore, it is important, first of all, to protect yourself with personal / personal protective equipment (PPE).

How to cut correctly

First of all, you need to correctly pick up the instrument. Right-handers hold the angle grinder with their right hand by the body. In this case, the circle is located on the left, and the gearbox on the right side of the machine. With your left hand you need to hold the tool by the handle, which is screwed into the body. The correct position of the handle is up. The protective cover should cover the disc and hands, casting sparks away from the worker. For left-handers, the handle is screwed in from the other side of the case, the protective cover is rotated and fixed in the desired position.

How and in which direction to cut, everyone decides for himself, given that when biting, the angle grinder throws out in different directions.

How to cut an angle grinder correctly: by yourself or by yourself

Angle grinders are in many farms and garages, but most owners do not know how to properly hold and use an angle grinder. Therefore, they make mistakes that can lead to marriage at work, which is even worse. To serious injuries. Remember that an angle grinder is a very dangerous tool. Therefore, before using it, you need to learn a few safety rules.

Correct start, stop and breaks

Before turning on the device, you should carefully inspect and carefully check the disc. Do not use tips with chips, delamination, cracks or any other damage.

Before connecting to the network, a cutting (grinding) wheel must be installed on the angle grinder with a pattern upwards, then tighten it with a special nut. The size as well as the permissible revolutions are indicated in the technical documentation for the tool.

When inspecting the tool, you need to check that:

There is no damage or cracks on the case;
Serviceability of the cable (cord), protective tubes and plug;
The handle is well screwed;
The circle is fenced, and the casing is securely fixed.

After that, the idle operation of the tool is checked. To do this, you need to connect the plug to the outlet, turn on the power button and the latch. Observe for a minute the work of the angle grinder. Make sure that it works without extraneous sounds, excessive vibration, and the disc does not touch the protective cover. When disconnected, the malfunction or functionality of the power button and latch will become clear. If everything is ok, you can get to work.

Interruptions in work are usually associated with overheating of the disc or angle grinder, changing attachments, the need to move the workpiece or the worker himself. In any case, you must first turn off the button, and then disconnect from the network. It is important to monitor the tool and avoid overheating.

Individual protection means

The name PPE, or personal protective equipment, is understood as means for personal use, which are used to protect against pollution, prevent or reduce the effects of harmful and dangerous factors. For most workers, this is workwear appropriate for the profession. It usually includes trousers, a jacket, a hat, closed shoes. Since the angle grinder is a hazardous tool, the clothing is supplemented with other protective equipment:

Glasses or visor;
Ear muffs or earplugs (ear plugs);
Vibration-insulating gloves;
Respirator, especially when cutting stone, tiles, concrete or slate.

The goggles will protect you from sparks, small debris or a grinding disc. The use of headphones or ear plugs helps to eliminate noise, thus avoiding difficulties with hearing after work. The gloves will protect you from abrasion and vibration. A respirator against a large amount of dust generated.

Cut from yourself

This is a very good way, but it is important to observe one condition. Cut from yourself, with sparks under your feet. In this case, when biting the disc, the angle grinder throws out, therefore it is not capable of causing harm to health. In this case, the drawn cutting line is clearly visible, and besides, there is very little chance of doing something wrong. The disadvantage of this method is that sparks fly into trousers and under your feet.

Safety when working with an angle grinder

Grinding and cutting power tools are hazardous activities. Therefore, when working with an angle grinder, you must take into account the possibility of direct or indirect action of factors hazardous to health:

Cold or heat;
Poor illumination of the workplace;
Strong noise, vibration from a typewriter;
Great physical activity;
Rotating parts of equipment;
Falling objects (processed materials);
Flying off sparks and solid particles of parts;
Work at height, depth or in a confined, hard-to-reach place;
Danger of electrical injury.

It is possible to minimize the action of hazardous factors, and as a result, to preserve life and one’s own health, by observing the safety rules when operating devices with open rotating parts. To do this, you need to use personal protective equipment (abbreviated as PPE), fix the workpieces well, choose a safe place, start and finish work correctly.
