The best manufacturers of drills - which company to choose

At the moment, you can find on sale a great variety of a variety of perforators, the price level for which can vary by 2-3 times. Well-known Japanese and German manufacturers of industrial equipment are rightfully considered to be the best manufacturers, whose product quality is not in any doubt:

1. Bosch

2. Makita

3. Hitachi

4. Stihl

5. Dewolt

Before you make your choice in favor of a particular model, you need to familiarize yourself with the characteristics, as well as take into account all the positive and negative aspects of a particular device. It is easiest to do this by studying the catalog characteristics of the model, as well as reading the reviews of real buyers on the Internet.

Kinds of punchers

At first glance, perforators are almost the same as drills. The difference between them becomes clear when the device is put into operation. Due to the special design, the perforator can not only drill holes, but also perform translational shock actions that greatly simplify destructive work (for example, the destruction of partitions, walls and concrete masonry), and also allow you to make holes in a few seconds in which the drill is powerless. Currently, the following types of drills.

220V powered rotary hammers

Simple, easy to use and quite powerful devices. The power source for these models is a regular household network, and therefore their real power consistently corresponds to the stated. They are the most common devices, both in domestic use and during construction and installation works.

Virtues

• High power and performance;

• Democratic value;

• The convenient case in operation equipped with anti-vibration elements;

• A large number of additional accessories;

• Three different modes of operation (drilling, drilling with a shock load, shock load without drilling);

disadvantages

• Power depends on the quality of the electricity supplied to the network;

• The need for regular service due to the constant shock loads on the mechanism;

• The range of use depends entirely on the length of the power cord;

Battery Operated Hammers

Devices, which serves as the power source of the battery. When it is similar to the classic models, the functional is distinguished by increased mobility - not limited by the length of the power cord, which means you can work even in the field, without resorting to the need to use a gas generator. You have to pay for mobility: such devices are unlike their heavier network counterparts. In addition, the time of their battery life leaves much to be desired: it is unlikely to work for several hours in a row without charging a “battery”.

Virtues

• Maximum functionality;

• Independence from external power supply;

• Ergonomic body;

• Three different modes of operation;

disadvantages

• The battery life is directly dependent on the capacity and charge level of the battery;

• High price;

• Significantly greater weight compared to network counterparts;

• The battery pack is fragile enough: a fall even from a small height can break the device;

Pneumatic drills

Devices, the principle of operation of which is radically different from the two types described above. Such devices use compressed air as a power source, and therefore require a compressor in the immediate vicinity. They are widely used in industry, and especially where there is a developed network in which air is under high pressure. In addition, they have been used in explosive conditions, when the slightest spark can lead to ignition.

Virtues

• Work from compressed air;

• Minimum dimensions and weight of the device

• Differ in high performance;

• Allow to save electricity;

disadvantages

• The range of application is directly limited by the length of the hose;

• High enough price;

• Requires the presence of a compressor in the vicinity;

Fuel Punchers

This type of device is extremely original and more commonly known as a jackhammer. The basis of this type of device is a compact internal combustion engine operating on ordinary gasoline with the addition of oil for lubrication of the central piston group. Allows you to work away from the source of electricity and electrical outlet, having at hand only a can of gasoline. Widely used in the dismantling of buildings and premises, as well as during the repair of the roadway.

Virtues

• Efficiency;

• Maximum mobility;

• Ability to work away from the source of electricity;

• High power;

disadvantages

• High price;

• The ability to inflict too much damage;

• Increased noise and exhaust during operation;

• Dimensions;

Punch selection options

Power

Reflects the force of rotation of the device and the ability to quickly remove the dismantled concrete and other materials. The higher this parameter is, the more productive a particular perforator is. Power is measured in watts at certain revolutions of the electric motor.

1. For normal household use, a device whose power will be 600-800 W at 1200-1500 rpm is quite enough;

2. If necessary, serious installation work and drilling thick floors and walls need a more powerful tool, about 1-1.2 kW at 2000-2200 revolutions per minute;

Impact energy

A criterion that fully reflects the destructive ability of a particular device. Energy, as usual, is measured in joules, and the higher this parameter is, the easier it is for a perforator to destroy concrete, asphalt, brick walls and floors, as well as other types of surfaces that are similar to them.

1. For infrequent household use, devices with an impact energy of 3-8 J are enough;

2. Industrial equipment is almost always characterized by the ability to make strikes of greater force - about 10-15 J;

3. To carry out dismantling work on extremely hard surfaces, a punch should be selected, the impact energy of which will be at the level of 30-40 Joules;

Type of mounting drill

Three types of fasteners are most common:

1. SDS-Plus. The most common type of element that allows you to use all kinds of blades and chisels, and small drills for fixing fasteners. The diameter of the bore in these models is 25 mm;

2. SDS-Max. The landing element most often found in professional models. Designed for strength work with durable and hard materials. The bore hole has a diameter of 52 mm;

3. SDS-Top. A very specific type of professional devices, designed to work with drills with a bore diameter of 16 to 25 millimeters.

Modes of operation

Virtually all commercially available drills allow you to work in three main modes:

1. Drilling with a blow;

2. Drilling without impact is a direct analogue of an ordinary drill;

3. Punch mode, no drilling;

Maximum drilling diameter

It depends entirely on the type and diameter of the drill used. This parameter is directly related to the power of a particular device: the larger the hole diameter needs to be done - the more powerful the punch will be required.

Additional functions

Options that make operation as comfortable as possible. As a rule, we are talking about the following options:

1. Reverse - provides the ability to rotate both clockwise and counterclockwise;

2. Protection against overloads - allows you to maintain the operability of the device during power surges in the network;

3. Brush wear indicator - indicates when the brushes are worn and need to be replaced;

4. Additional handle - provides the most comfortable grip;

5. Lock the power button - allows you to work with the device without pinching the trigger ;;

6. The depth gauge is a useful thing, allowing you to make holes of the same depth;

7. Dust collector - an indispensable tool when necessary, "clean" work;

Which punch to choose

1. When choosing an ordinary household punch, you should pay attention to compact devices with a capacity of 500-700 W and a blow force of no more than 10-15 Joules. Cartridge Type - SDS +

2. When working away from a DC source, a perforator similar in parameters and powered by a battery with a capacity of 4-5 Ah will suit;

3. If we are talking about professional installation work, the choice should be given to a device with a capacity of 1.2-1.5 kW, a blow force of about 25-30 Joules. Type of cartridge used - SDS max;

4. In the presence of a compressor or a permanent air line, the best choice would be a pneumatic perforator. The type and power of the device is selected based on their own needs;

How much does a punch cost?

1. Ordinary household models cost about 5-7 thousand rubles;

2. Their battery counterparts are somewhat more expensive - the most popular models cost about 10 thousand rubles;

3. Perforators operating on gasoline cost about 25-30 thousand rubles;

4. Professional equipment designed for large-scale dismantling, the most expensive - on average from 40 to 60 thousand rubles;
