A hammer drill is a machine that has the function of drilling with a powerful impact. The hammer drill has many similarities with an electric impact drill, but it is designed more for working with durable materials (concrete, granite, brick, ceramic tiles). Electric drills cannot compete with a hammer drill in terms of impact power on the material. Modern dismantling or chiselling of durable materials cannot be realized without such a tool as a hammer drill. One of the best companies in the world that makes professional rock drills is Makita.

Characteristics

Makita was founded in the Land of the Rising Sun and is considered one of the best power tool manufacturers in professional circles. Makita dates back to the 15th year of the last century, when it began to produce electric motors. The first popular professional tool that made the company famous was the electric plane. To date, the range of the Makita company has about four hundred positions; screwdrivers and hammer drills are the areas that the corporation has been developing especially actively in recent years. Many innovative innovations have been introduced into these devices, for example, self-contained power supplies have been improved, which have become even more compact and energy-intensive.

Many of the corporation's production facilities have been moved out of the country to Asian countries, where labor is much cheaper. This allows Makita to be more competitive and invest in new models and developments. Makita's trademark and pride is its long-term partnership with the aerospace corporation NASA (USA).

Views

Hammer drills from Makita are in demand among both professionals and amateurs. In total, the company produces four dozen units, below are the most famous models. Makita HR2470 is a very compact cordless tool that has three modes of operation:

• drilling metal up to 12 mm;
• wood - 30 mm;
• concrete - 25 mm.

There is a safety device (clutch) that protects the hammer from jamming. All this allows the Makita HR2470 to work for a long time without interruptions. Unfortunately, the weak point of the device is the inability to function for a long time in crushing mode.

Makita HR2800 - a professional unit that meets all the requirements, is able to withstand heavy loads. It works properly in a variety of modes, there are no shortcomings.

Makita HP4001C - high-power perforator (1100 watt engine), 267 rpm 2, 8 thousand strokes. Has two modes of operation, automatic speed control. Ideal for dismantling as well as for finishing work. Impact force 10 J, holes can be made up to 400 mm in diameter (when working with a crown up to 15 mm). There is a rich functionality, effective regulation of work using electronic blocks.

Makita HR2432 has an installed dust extraction system. The device is capable of operating in any modes, the main functionality is borrowed from the Makita HR2470 model.

Rechargeable

Battery-powered devices can operate autonomously, which is often extremely necessary. Construction work is associated with hard-to-reach locations, where it can be incredibly difficult or almost impossible to stretch an electric wire. Experts calculated: labor productivity, due to the factor of autonomy, increases by an average of one third. Modern technologies make it possible to create economical engines and powerful battery devices. The developments of the Makita company in this area allow the corporation to be at the forefront of global technological progress.

As an example, it makes sense to mention such innovations: a large and small power tool is produced in which the engines are arranged vertically.

Such units are distinguished by:

• power;
• profitability;
• high revs;
• compact batteries (from 18 volts).

All dynamic units are coated with a high-strength carbon composition, which is not inferior to titanium alloys in terms of wear resistance.

With a vacuum cleaner

Makita offers innovative dust extraction solutions. A small vacuum cleaner, which works in conjunction with a perforator, makes it possible to effectively remove microparticles. Perforators from "Makita" are usually produced with dust collectors, such built-in devices significantly extend the service life of the units. A breakdown of the dust container or built-in vacuum cleaner leads to overheating of the unit.

At the end of the working day, the rotary hammer must be thoroughly cleaned of construction dust. With intensive use, a power tool is handed over to a service center on average once every three to four months. It is also recommended to take breaks between the work of the punch, the optimal mode is 20 minutes of work and 15 minutes of "rest".

Professional

As an example of a professional tool, consider the Makita DHR 242 rotary hammer.

The model is adapted for various working conditions:

• dismantling of walls;
• installation of communications;
• finishing facilities.

A vacuum cleaner can be connected to the perforator. The unit is compactly located in a branded plastic box. The set includes two 18 V ion chargers, each with a capacity of 3 A / h. Also, the battery can be equipped with a standard energy cell. You can charge such a unit in just a quarter of an hour, while the cost of battery technology does not fundamentally differ from the usual one.

Punch operating modes:

• drilling is simple;
• drilling and chiselling;
• chiselling.

" Shoulder "- this is a special mode in which the punch from "Makita" can work. In this case, the DHR 242 can effectively remove tile chips from surfaces. Punch length 330 mm. Small weight, 3 kg.

The device contains:

• standard sds-plus cartridge;
• there is also a key cartridge in the kit;
• there is a function for removing dust (three modes).

The vacuum cleaner works autonomously, it has its own engine. The functionality is arranged ergonomically, it is comfortable to work with such a tool.

Main factors:

• 12 months warranty;
• 2 speeds;
• impact force - 2 J;
• the number of beats - 4700 per minute;
• the number of revolutions - 955 per minute;
• drill diameter (maximum) - 14 mm.;
• there is a screwdriver;
• rotation adjustment;
• fixing clutch;
• unit price - about 30 thousand rubles;
• the price of a vacuum cleaner is about 14 thousand rubles.

Shock

One of the best models of Makita corded rotary hammers is the HR 2641. It combines three important qualities:

• power;
• excellent functionality;
• affordable price.

The device works in three modes, it can be used both within a private household and for finishing work by professional teams of builders. The weight of the perforator is only 3.2 kg, the impact power is 2.45 J. There is a useful function: the ability to set the chisel at different angles, which gives a chance to drill from different angles.

The frequency of blows exceeds the figure of 4, 5 thousand, the frequency of the torque is regulated by the electronic unit. It is also possible to use the hammer drill as a screwdriver (there is a reverse). The working area is illuminated by a special LED flashlight. Handles and buttons are thoughtfully and comfortably arranged, the price is just over ten thousand rubles. Of the negative aspects, we can mention:

• short cord;
• buttons quickly become clogged with construction dust, which is why they have to be cleaned quite often.

How to choose?

The criteria for choosing the Makita perforator are based on information: what kind of work will be performed predominantly by the perforator. All this will affect:

• on the power of the perforator;
• what battery is needed for the device;
• how many modes of operation are required (three-mode, two-mode);
• what additional accessories should be in the form of attachments.

As an example, the following fact can be cited: a perforator is being bought for dismantling premises. The unit is supposed to be used almost daily for many hours. In this case, it is required to purchase lithium chargers (Li-ion), they are more expensive than nickel-cadmium (Ni-Ca) chargers, but they provide a longer operating mode (50%). It is clear that with intensive use, lithium cells will pay off in a short time.

If the hammer drill will be used rarely, from time to time, then cadmium batteries should be purchased. Cadmium - Nickel (Ca-Ni) chargers are much cheaper; they do not have such a large capacity of energy return, however, they serve much longer than lithium ones, it can be profitable to work with such energy elements.

Components

Standard accessories for the Makita perforator assume the presence of such units and parts:

• brushes;
• cartridge;
• bump stop with replaceable drill;
• borax;
• anchor;
• nozzles;
• chisel;
• peaks;
• drill;
• diagram and instruction manual.

Operation and storage rules

Perforators of the household series can usually work continuously for no more than twenty minutes, then they need to be given a break of about 5-6 minutes. Such a device can work no longer than twenty hours every week. All recommendations for use are attached as a reminder in the instructions, which should be carefully read before starting work.

Here are the excerpts:

• the workplace should be well lit;
• do not work in rooms where there are explosive, flammable materials;
• children must be kept away from the operating unit;

• while working with a perforator, it is necessary to take a stable position;
• be sure to use glasses, gloves, respirator;
• special shoes and a helmet must also be used when performing the corresponding work;
• as necessary, it is imperative to use clamps, clamps, vices during work;
• the perforator should not work with overload - this leads to a breakdown of the device;
• if the ON / OFF key is broken on the punch, it is forbidden to work with it;
• when debugging the operating mode, disconnect the unit from the power supply;
• preventive maintenance should be carried out in a timely manner;

• regular inspections of the unit should be done, checking it for deformations or other breakdowns;
• nodes from other perforators can be traumatic due to their discrepancy;
• punch repair work should be carried out only in a specialized service center;
• all nozzles, consumables for a perforator must be "native";
• cleaning plastic surfaces with aggressive chemicals leads to their deterioration;
• regularly check the presence of grease in the unit: for this it is recommended to open the cover on the perforator body;
• starting to work with a drill, you should always coat its tail end;

• you can not under any circumstances use crowns instead of a drill;
• before hammering in any wall (concrete, brick), the unit must idle for a couple of minutes;
• during work, additional physical efforts must not be applied - this can lead to overheating of the electric motor of the perforator;
• regular inspection of drills and nozzles should be done;
• all openings through which air exchange takes place must be regularly cleaned.

Comparison with other models

The domestic company Interskol and Makita have the highest sales of power tools in Russia. Makita is a renowned company, it produces a professional power tool that can be operated daily for 8-10 hours. Such requirements imply a large functional resource. "Interskol" focuses more on the production of household tools, the resource is laid less than that of Japanese technology, but the products of "Interskol" are much cheaper. For household needs, when a perforator or drill is needed every six months, you cannot find better equipment.

In terms of the breadth of the assortment, the Russian company is in no way inferior to the eminent corporation from the Land of the Rising Sun. The advantage of Japanese products is that each model is carefully thought out and worked out, it is convenient and pleasant to work with such a tool. According to the quality criterion, Makita is the undisputed leader.

Disadvantages of Interskol:

• a backlash sometimes appears in the tooling, which affects the accuracy of the work;
• the instrument is noisier;
• hammer drills are larger and weigh more.

As a conclusion, we can say: if you need a tool for professional daily work, then you should take Makita. Interskol is ideal for household chores.

Bosch and Makita are the two largest players in the global power tool market.

Bosch also specializes in the following areas:

• production of components for cars;
• production of turbines and household appliances.

Makita is "sharpened" for power tool production only , in terms of the breadth of models in this segment, the company is not inferior to Bosch, and in some ways even surpasses the German corporation. For example, Makita makes electric hammers - over twenty positions - while Bosch makes only five. The Bosch Green Line is a tool designed for household needs. The Blue Series is a tool for professionals. It makes sense to compare only "blue" "Bosch" with "Makita". Most often, Bosch bypasses Makita in terms of innovation, the scientific and technical base of the German giant is richer. The SDS-Plus cartridge (a device for fastening drills for rock drills) was invented and implemented by a German company.

In general, it can be stated that German and Japanese perforators differ little: there are minor advantages and disadvantages, but here a closer comparative examination of a particular model is required. For example, "grinders" from "Bosch" are more isolated from dust, while "Makit" has more practical functionality.
