How to choose a quality puncher for home

Iron sole

  • ceramics and cermets are used for expensive irons. They glide easily over the fabric and do not jam it. Not scratched, easy to clean. Ceramics keep warm for a long time;
  • stainless steel. the material is durable, does not scratch, has an average heating / cooling rate, easily glides on the fabric and is easy to clean. Often such a sole is complemented by special spraying and holes;
  • aluminum is an excellent heat conductor. The outsole heats up and cools down quickly. Irons are inexpensive and lightweight, but quickly deteriorate and easily damaged. Over time, scratches appear on the sole. Small burrs from them on delicate fabrics form puffs or cuts. Non-sprayed aluminum sole leaves shiny marks on wool-containing fabrics;
  • Teflon. the coating does not stick to the fabric and does not burn through things, glides well during ironing. It is easily scratched by metal clothing accessories, which leads to deformation of the sole.

Power and energy consumption

The power consumption of the iron ranges from 200 W to 3200 W. The higher it is, the less time it takes to heat the sole and the faster the vaporization occurs. Saves time during ironing:

  • powerful irons (from 2500 W) are indispensable helpers for a large family;
  • with an average power (1500-2500 W) are optimal for small families;
  • low-power models (up to 1500 W). for road models and apartments with poor electrical wiring.

The amount of electricity consumed by the iron depends on the power. They are not assigned an energy class. Unlike other household appliances, the iron does not consume a lot of electricity. The most economical are irons with low power ratings. Many manufacturers provide special operating modes to conserve energy. There are steam models with reduced energy consumption due to the ergonomic steam supply. Using such an iron, you can save up to 20% of electricity.

Cord length

The length of the power cord is from 0.8 to 4 m.For comfortable use of the iron, the optimal cord is from 1.9 to 2.5 meters.

The wire moves “left and right” and “back and forth”. Convenient models of irons in which the power cord has a free ball attachment and rotates 360 °, preventing the possibility of twisting the wires during ironing.

What is the best center punch?

There are irons with wireless connection. They are connected to the network with a stand that has a wire. Heating of such irons is provided through contact with the stand. When the user takes off the iron. it does not heat up, puts it on the stand. it heats up. Cordless irons are convenient in that they allow free movement of the user. Wires don’t get tangled.


Horizontal steaming. normal steam supply during ironing.

Vertical steaming. clothes are ironed on a hanger. This type of steaming is convenient if you need to quickly iron out the formed folds before leaving the house.

For high-quality irons, the “steam release” or “turbo-steam” function delivers steam intensively. Clothes made of dense fabrics (linen or denim) require enhanced ironing using a “steam boost”. The steam is emitted as a self-cleaning iron. The water tank with a strong steam jet is freed of accumulated dirt and scale particles. A good steam boost in conventional irons is considered to be from 90 g / min, and in steam generators. from 120 g / min. It takes some time for a large portion of steam to form, which is why in conventional irons the steam boost is delivered at short intervals.

Steam irons and some conventional irons have separate steam reservoirs and high steam rates for powerful continuous steam.

Steam supply

Steam irons with hot moistening, faster and easier to smoothen wrinkled fabrics, including overdried laundry.

Steam is supplied in irons through a multitude of holes in the soleplate. The more holes there are, the better the fabric is moisturized and steamed. The effectiveness of smoothing depends not only on the number of holes, but also on their location. The classic version involves the accumulation of micro-holes on the toe and heel of the sole; larger holes in 1-2 rows are located along the sides.

The steam supply has several technical solutions. Distinguish between horizontal steaming, vertical steaming and. as additional options. steam emission and spraying.

The amount of steam generated by the iron during operation per minute is measured in grams. As a rule, it is produced from 30 grams of steam per minute or more. To cope with any kind of fabric, the steam boost must be over 100 g / min. In many models, a regulator of the intensity of the steam supply is installed, which is located on the front of the iron handle. It regulates the optimal steam rate according to the type of fabric to be ironed, its thickness and the degree of wrinkle.

Steam generator

The steam generator is a separate unit with a heater and a large water boiler in which steam is generated. The steam generator and the iron are connected to each other by a special hose through which ready steam is supplied to the iron. The length of the steam hose varies from 1.5 to 4.0 m.

A hose shorter than 1.5 m restricts movement, and too long can become tangled during operation. Powerful heater and high pressure generates steam quickly and delivers it continuously.

Expensive semi-professional and professional irons are equipped with a steam generator. Thanks to the large tank, it allows you to iron with intensive steam for several hours without interruption.

Advantages of the steam generator: ironing takes several times less time than a conventional electric iron, and the iron itself becomes more maneuverable and light due to the absence of a water tank in its body. Disadvantage: it takes up a lot of space.


Spray. function of dampening the fabric with a spray gun.

A spray device located on the iron spout, at the push of a button, supplies water to the fabric. It is used when ironing thin fabrics where the use of steam is undesirable.

Drive unit

The tool can be equipped with a vertical and horizontal electric drive. In the first case, the gearbox and the motor are cooled very effectively, which provides the tool with a certain margin of endurance. With a horizontal arrangement of the electric drive, there is an increased convenience of working with such a tool.


Depending on the design characteristics, the hammer drill is supplied with certain accessories and has the functions necessary in each specific case:

  • a persistent handle that changes position and makes work as comfortable and completely safe as possible;
  • depth gauge limiter to prevent excessive immersion of the working drill;
  • a set based on working tools in the form of peaks, drills and bits, thereby increasing the functionality of the device;
  • replaceable or additional (keyless, key type) chuck, which is supplied with a special adapter;
  • control electronics, easily controlling the speed and frequency of impact work;
  • a safety clutch that quickly stops work in the event of a jammed operating drill;
  • reverse, trigger lock and a system of illumination of the work area to increase the accuracy of the perforation.

By the type of power supply, network models are distinguished, characterized by the optimal combination of price and performance indicators, as well as battery devices that are mobile, but need periodic charging. In this case, the drill, bit and peaks can be fixed in the “SDS” (under the liner) and “SDS-max” (rigging with a base) option. Rotation of the chuck with a drill is carried out at a speed of 600 to one and a half thousand revolutions per minute.

How to choose a good rotary hammer for homework

Today, branded models are produced by domestic manufacturers and many popular foreign companies. At the same time, the correct independent choice of a perforator often puts amateur craftsmen in a rather difficult position.

In addition to the price of the device and power indicators, it is necessary to pay attention to the location of the drive, operating modes and other important parameters.

The weight of the working tool is presented in three main categories. Models up to 3 kg are light and easy to use, but they can solve a limited range of tasks. The devices in the middle weight category (from 3 to 5 kg) have universal functionality, and the highly specialized ones include heavy professional punchers.

Working hours

Modern rotary hammers work in the mode of standard and hammer drilling, as well as chiselling. Each model contains a rational solution and excludes the presence of component parts designed to perform operations unclaimed by consumers.

How to choose a quality and inexpensive rotary hammer for your home

Dust cleaning capability

The durability of the device is ensured by a passive or forced dust extraction system. The basic configuration is characterized by the presence of the first option, and in some models a preventive dust removal system is installed. The indicators of the power consumed by the device are necessarily taken into account when performing work, if there is no stable electrical supply of the tool.

Naturally, a significant number of functions makes the device more expensive, but it is possible to perform work with such a device comfortably and easily. At the same time, there is absolutely no reason to overpay for functionality that is not needed. For household needs, it is enough to purchase a middle-class rotary hammer that will cope with simple repair work at home.

No matter how attractive this or that model of perforator is in terms of appearance and price, experts do not recommend making hasty conclusions when choosing such a tool. Only as a result of a thorough analysis of the individual needs and potential of the device can one correctly determine the feasibility of investing money in the purchase of a construction tool.

Impact frequency

If we calculate how many times in one minute the piston of the device strikes against its firing pin, we get a value called the frequency of strikes. The larger it is, the higher the hole punching speed. The performance of a rock drill depends on both the frequency and the energy of the impact. The manufacturers that produce the most durable and efficient devices in their models harmoniously combine these two parameters.

Therefore, it is better to pay attention to reliable brands, whose products are of excellent quality and amazing durability. Specifically, we will talk about the best manufacturing companies a little further.

Rotary hammer power

Hammer drills are less powerful than electric drills. This is because drilling is much harder than drilling. Therefore, the punch shaft during operation does not require such a high rotation speed as that of a drill. For devices with different types of cartridges, the power is different. Models with SDS-Plus cartridges consume 400 to 800 watts. Rotary hammers with SDS-Max cartridges have a capacity ranging from 1 to 1.2 kilowatts. In fact, when choosing this tool, you should not focus on power. this is not the most important parameter.

An impact drill and hammer drill are not the same thing

Some people mistakenly believe that a hammer drill works the same way as a hammer drill. But this is not so. although such a drill is called a “hammer drill”, the principle of operation of these two electric tools is strikingly different. Yes, they both punch holes, but the blows have different strengths, as well as different origins.

The hammer drill works as a punch through the gearing of two wheels called ratchets. At a certain pressure on the drill, an oscillatory movement of its axis occurs, which allows you to make a hole. But the performance cannot be high, and the blows are rather weak. Therefore, hard concrete, for example, cannot be pierced with such a drill.

But the hammer drill is just intended for drilling stone, brick and concrete. It also allows you to transfer force to the working edge of a lance, blade or drill, allowing these tools to work with maximum efficiency.

The hammer drill uses an electromechanical or electro-pneumatic type mechanism as the main structural element. Thanks to it, an impact force is created that is sufficient to punch through concrete or stone. In this case, the master does not need to press hard on the handle of the puncher. Some models have a mechanical percussion mechanism similar to that of a drill, but it is less durable than an electromagnetic or pneumatic mechanism.

The piston and the mechanism of the pneumatic impact system, as a rule, are equipped with L-shaped rock drills.

The mechanism of the “drunken” bearing type, which, while rotating, forces the firing pin to strike, such a mechanism is equipped with narrow perforators.

So, if you compare the mechanical and pneumatic mechanisms, you can see that the latter greatly facilitates work on a hard surface. When using a mechanical percussion device, three times more force is required than when using a pneumatic device. When choosing a hammer drill for home, it is better to pay attention to more modern models, and safely forget about mechanical ones.

The following functions can be built into the hammer drill:

  • Drill depth gauge helps you know if the drill has reached the correct mark.
  • The gearshift mechanism comes in handy when you need to switch from drill to drill or vice versa. Because they have to move at different speeds.
  • Reverse rotation of the shaft will help out when the drill gets stuck in any surface.
  • A soft start and a device that protects against overheating will help to avoid troubles that promise a breakdown of the device.
  • Stabilization of the shaft speed during fluctuations in the load force is a very useful function.

Spindle speed

The rotational speed of the punch shaft is lower than that of the drill. this has already been mentioned above. Depending on the class of the device, the value of this value can be from 600 to 1500 rpm. The rotational speed decreases with increasing power and productivity of the rock drill. this is due to its design features. Indeed, for productive models, the optimal tooling diameter is quite large. In general, the shaft of the device rotates only in order to remove dust after drilling. A small drill has to rotate faster, and a large one. slower, otherwise it will wear out too quickly.

Models of rock drills with high shaft rotation speed are heavy, which does not facilitate ease of use. In addition, such high-speed devices wear out the spiral grooves very quickly, with the help of which the drilling waste is removed from the place of work. Because of this, the device begins to heat up quite a lot, and as a result, it can even jam in the hole.

What to consider when choosing a hammer drill

This tool can be: with one drilling mode, with two modes (drilling plus hammering), as well as with three modes (chiselling is added to the previous two modes). In addition, rock drills are classified by weight into heavy, medium and light. The latter will not be heavier than 4 kilograms, the average will “pull” from 4 to 5 kilograms, and the heaviest devices of this type can weigh 5-10 kilograms or more.

Punch operating modes

Now let’s take a closer look at how perforators with a different number of operating modes differ from each other. So:

The simplest devices are single-mode. They work in the same way as an ordinary drill. If you have to drill wood and metal surfaces, then they are quite suitable.

In a dual-mode device, the axis is capable of not only rotating, but also oscillating during rotation.

The three-mode hammer drill as an additional function has the ability to strike without spindle rotation. Such a device is the most versatile, it can simply drill, drill and chisel and just chisel.

The variety of models of rock drills suggests that each of them can have different modifications. over, they can be performed with one, two or three modes of operation. If we talk about the latter option, then it certainly costs more. But if you have to carry out work, both on drilling, so on drilling and crushing, then you definitely need to stop at a three-mode device.

When choosing a device, both its shape and design play an important role. Holding the device in your hand, you need to feel that it will be convenient to work with it. At the same time, pay attention to whether there are side handles that can be easily removed. great if this option is provided. It will help if you have to drill in a tight corner, for example. He took off the handles. and work with all the conveniences.

How to choose a puncher for personal use?

Several decades ago, only powerful electric drills equipped with drills for metal and concrete were used in everyday life. A truly branded, specialized tool was sold only abroad, you could not just go to a construction supermarket and choose a suitable device.

Energy and frequency of impacts

For a hammer drill, the impact function, measured in joules, is very important. The performance of the device, as well as the diameter of the hole to be machined, depends on the impact energy. For daily work with a hammer drill, this is one of the most important indicators.

It is essential that an impact drill at the “maximum” will very quickly deplete its resource, and with a hammer drill they perform this work for a long time without wear, especially with a single-mode model.

The frequency of impacts also affects the speed of the tool. The more often the piston of the perforator strikes the working element, the faster the hole is punched.

It turns out that energy and frequency determine the level of performance. When choosing a perforator yourself, you need to evaluate the amount of work on chiselling, then, according to the specified characteristics of the impact frequency, calculate the approximate productivity.

What is the difference between a drill and a hammer drill and vice versa

The hammer drill is characterized by a longitudinal axial movement of the working part, similar to an impact drill. Therefore, hammer drills are confused with a heavy drill. In words, there is practically no difference, however, the hammer drill functions on the basis of pneumatics, and any impact (heavy) drill works thanks to mechanics.

We come to the conclusion that the hammer drill should be larger and more massive than a drill with an impact function.


The device and characteristics of the punch

All punchers are divided into three types in terms of functionality:

  • Single-mode. Impact drilling function only. Most often, such perforators are not used in everyday life, but are used as professional additional equipment for narrow purposes.
  • Dual mode. Hammer drilling plus classic drilling or chiseling only.
  • Three-mode. The tool is equipped with all the functions specified in paragraphs 1 and 2.

The choice of a hammer drill is based primarily on the characteristics of power and impact force. The higher these figures, the better the hammer to be fitted.

The impact force of the tool is sometimes not proportional to the power due to design features.

Types of working chuck for rotary hammer:

  • usual;
  • quick-clamping.

Which drill chuck to choose? For household or household chores, the keyless keyless model is best suited. Changing the nozzle in this version is convenient, easy and quick.

Rock drill classification by weight:

  • Lungs. Up to 4 kilograms. Power is no more than 700 watts. Only have SDS-plus chuck for 26 mm drill bits.
  • Average. 4 to 8 kilograms. Power from 700 to 1500 watts. Depending on the equipment, both SDS-plus and SDS-max are equipped.
  • Heavy. than 8 kilograms. Power is over 1500 watts. Equipped only with SDS-max chuck for diameters up to 60 mm.

Bosch equips its latest rock drills with SDS-top chucks for diameters from 16 to 25 mm.

How to choose a hammer drill for home

The best way to start the selection is to build on weight and power. Super-productive models for the home will definitely not be needed.

Domestic rotary hammers are mid-range tools in cost, power and weight.

Suitable criteria for home conditions and the following brands:

  • Power from 600 to 900 watts.
  • Shock 1.2 to 2.2 J.
  • Three-mode medium punch. Drilling, hammer drilling, non-rotating impact.
  • The rotation speed is necessarily regulated.
  • Anti-jamming clutch.
  • Keyless chuck.
  • Replacement branded cartridge included.

According to these characteristics, three leading brands are distinguished:

  • Makita. Sufficiently lightweight drills and hammer drills, with a warranty of several years. They have established themselves as tools for everyday household work, easy repairs. Average market price available, easy to operate. How to choose a hammer drill for home is this brand? Users refer to the Makita RK 2450 model. The required (useful) power is 700 watts, a shock of 3 joules, revolutions up to 4.5 thousand.
  • Bosch. German quality and assembly. Leading edge in professional power tools and household equipment. Any models have been tested by time and weather conditions. Rotary hammers are equipped with the function of precise adjustment of the nozzle speed (drill, drill). When purchasing equipment from this manufacturer, pay attention to the color of the case. Blue classifies precisely the professional purpose. The most popular model is BOSCH GBH 2-24 DF. 790 watts, 2.7 joule impact, complete with SDS-plus interchangeable chuck and classic keyless chuck.
  • Hitachi. The best tool in our market from Japan. Priced in the same category as the Makita, but some power tools, including rotary hammers, are lighter in weight. Are you wondering which hammer drill to choose from this manufacturer? Pay attention to the Hitachi DH 22 PG, 620 watts, 1.4 joules of impact and weighing only 1.9 kilograms.

You do not need to trust a consultant in the selection of a perforator, or any other technique. The maximum is to listen to recommendations. You need to choose and buy a model that best suits your personal requirements.

What to consider when choosing a hammer drill

During construction and major repairs, a hammer drill is an irreplaceable thing. As soon as the manufacturers started to release the tool, the work process improved significantly. Now, the range of rotary hammers is large. they are produced under the logo of each brand specializing in the production of construction tools.

And often, a question arises before the master about buying the right tool. This question is quite important, since the Bosch hammer drill cannot be called a cheap tool and in order to correctly approach the purchase, you should understand the principle of its operation and important design features.

To begin with, it is worth noting that the punch can be equipped with modes such as:

hammer drilling;

impact without drilling.

Due to the presence of three modes in the hammer drill, the tool can be called universal in the field of construction work.

By weight, perforators are classified into:

It has already been said that its power depends on the mass of the tool. Therefore, before buying, you need to decide what kind of work the perforator will have to perform.

There is another classification of rock drills, namely:

The division of rotary hammers into professional and household ones depends on the capabilities, quality and power of the tools.

Working Modes

The design and characteristics are important when choosing a tool, but also what modes of operation the tool is equipped with plays an important role.

Some rotary hammers have only one mode and work like a regular drill. For punching holes in materials such as metal and wood, they will work. A hammer drill with two modes is when the axis not only rotates, but also provides oscillatory movements at the moment of rotation. The hammer drill with three modes can strike without rotating. This tool has a more versatile purpose. It can be used to drill, hammer and hammer.

The wide range of Makita rotary hammers implies the presence of various modifications. And, at the same time, they can be 1-, 2- or 3-mode. A three-mode hammer drill is more expensive, but this type of tool will help in any situation.

When choosing a hammer drill, it is important to take into account its design, design features, shape. It is recommended that you personally choose a tool when you can directly contact with it: hold it in your hands, check the control system, ease of holding, and much more.

An impact drill and hammer drill are not the same thing

A common misconception of many craftsmen is that they identify a hammer drill with a drill. The drill is undoubtedly one of the most popular universal construction tools, but the hammer drill is also indispensable as a tool for various types of work. Structurally, these two tools are very similar, nevertheless, they have different principles of work from each other and in order for the work to go smoothly, quickly and as it should, it is necessary to understand the difference between the devices under discussion.

A hammer drill is a tool designed for making holes in material and percussion in relation to not particularly dense materials: concrete and stone. An impact drill performs the same function. Except that the hammer drill is a more productive tool in impact and the impact function is still the main one, while the drill is secondary. Impact drills, as a rule, have the ability to turn off the impact function, while a hammer drill, on the contrary, can work like a jackhammer without a drilling function.

Due to the powerful impact action, the hammer has a different cartridge. As in a drill, the drill is not clamped, but simply inserted. And, of course, special drills are needed for the special hammer chuck.

The hammer drill is not suitable for making holes in metal or wood, but there is no better tool for drilling concrete. If the drill is used, as a rule, for repairs, then the hammer drill is ideal for construction and finishing work. And, leaving only the shock mode, with the help of a puncher, you can make grooves, dismantle, destroy unnecessary material and much more.

Regarding the technical characteristics of the hammer drill: the power plays an important role in it, which has a minimum value of 400 W and the impact energy, measured in J. For many manufacturers, the capabilities of the hammer drill can be determined by the weight of the tool.

How to choose a hammer drill. criteria for choosing a hammer drill for home and permanent work

The word “puncher” from the Latin language can be translated as “to punch”. A perforator is a drilling tool that provides longitudinal-axial movements with the rotation of the working element.

In order to create an impulse that the user directs in relation to the material being processed, an electromagnetic and sometimes pneumatic mechanism is used. The power of the tool is determined by the impact energy and engine power.

Structurally and in the way of work, a hammer drill is in many ways similar to a drill. However, there are differences. differences that can play in favor of the puncher.

Additional functions

Technologies are developing very rapidly and, the average user, requires much more from modern tools. Tool manufacturers equip their products with features that can facilitate use or provide additional protection for both the instrument and the user. There are standard functions that are most often used in modern models, but some manufacturers have gone further and equipped their tools with “business cards”.

Here it is worthwhile to understand that all additional functions will affect the cost of the puncher and, when deciding which tool to give the decisive vote to, you should make sure whether these additional functions are really necessary.


The hammer drill is less powerful than an electric drill. This is because drilling is much more difficult than hammering. In this regard, the punch shaft does not need the rotational speed that the drill should have. Depending on the type of chuck, the power of the tool differs. The power of the hammer drill can fluctuate in the ranges of 400-800 W and 1-1.2 kW, depending on the cartridge used. So, when buying a hammer drill, it is not necessary to pay attention to the power of the tool.

Chuck type

The type of chuck is important for a hammer drill, as it is the main working element of the structure. The weight of a barrel rock drill depends on the chuck used. If the applicant is looking for a lightweight device, then you need to choose a model with an SDSplus cartridge.

Professional models differ both in the type of cartridge and in a more significant mass. Rotary hammers with SDSmax can weigh up to 11 kg. The overall dimensions of such a tool are also large. The hole that this punch will pierce can be more than 5 cm.

Not so long ago, manufacturers began to produce rotary hammers with SDStop chuck. The model with such a cartridge is perfect for making holes with a diameter of 1.6-2.5 cm.
