Review of the best BOSCH rotary hammers in 2020

A hammer drill is a construction tool that performs such types of work as drilling, chiseling and simultaneous drilling and chiseling. It is an indispensable and necessary unit for solving from simple to complex, from everyday to professional tasks in the fields of construction, repair and decoration. Below we will talk about the criteria for choosing a device, as well as about the best perforators from BOSCH.

How to choose rotary hammers?

The principle of operation of the perforator lies in the mechanism of impact force, with the help of which the destruction of the treated surface is carried out. That is, the construction equipment performs rotational and translational movements that destroy the material.

The main criteria for choosing electric tools include:

• Tool type;
• Power;
• The number of operating modes;
• Impact force;
• Weight;
• Speed ​​of revolutions and frequency of blows;
• Cartridge type.

Tool type

Due to the way the electric motor is located in the body of the power tool, rock drills can be divided into vertical or horizontal. Vertical ones are more popular among professionals, as they have high power, which, in turn, reduces the cost of human resources and time, and quick cooling of the unit.

Horizontal ones are more convenient for drilling holes in narrow openings, therefore they have an elongated shape, which perfectly helps in carrying out work at home.

Power

It is the main and main criterion when choosing a rock drill, because the power significantly affects the quality and productivity of the work performed. Construction and renovation specialists divide rock drills into 2 categories:

• Household - up to 900 W;
• Professional - from 900 watts.

If there is a need to drill holes a couple of times a year, then a household power tool is suitable. But if a hammer drill is necessary for drilling thick concrete walls, leveling hard surfaces, then it is better to choose high-power construction equipment, that is, a professional category.

Number of operating modes

As a rule, hammer drill models have 1, 2 or 3 operating modes. These modes are presented as:

1. Drilling;
2. Drilling with a blow;
3. Blow.

A tool with a drilling mode functions as an ordinary electric drill, which is perfect for processing materials such as wood. Units with the 2nd mode of operation are the most common and popular models, since thanks to the rotation and translational movements, it is possible to make holes in the hardest and most dense surfaces. Hammer drills do the work of a jackhammer.The best tools are those with all 3 modes of use.

Impact force

The efficiency of operation and productivity of the unit primarily depend on the force of impact. This characteristic determines the energy that the electric tool transfers to the material being processed for its subsequent destruction. Basically, perforators are chosen with an impact force of 2.7 to 4.4 J.

Weight

By weight, the construction tool is divided into

• Lightweight (less than 3 kg);
• Medium (3 to 5 kg);
• Heavy (over 5 kg).

The heaviest rock drills are naturally powerful. The most convenient models are those with a mass in the range of 2-3 kg.

RPM and impact frequency

This characteristic determines the number of revolutions of rotation of the cartridge and translational movements per unit of time. These values ​​usually range from 240 to 2400 rpm and from 2200 to 5800 bpm, respectively. For household work, models up to 1500 rpm and 4500 beats / min are suitable.

Cartridge type

It depends on the cartridge how and what nozzles and what size will be attached to the hammer drill.

You can also additionally pay attention to such characteristics as:

• Rotation speed controller;
• Smooth start;
• Safety clutch;
• Reverse mode;
• Release button position lock;
• Anti-vibration system.
