Classification

In order to understand how to highlight the disadvantages and advantages of specific models of Dexter rotary hammers, it is necessary to have a general idea of ​​the signs by which this group of power tools is classified.

• By power. The power of rock drills usually ranges from 500 to 2000 watts. The power of the device directly determines the force of its impact. The stronger the material to be influenced, the more power of the perforator should be.
• By the type of engine placement. The placement of the engine in rock drills can be horizontal and vertical. Horizontal models are usually less powerful, but more maneuverable due to their elongated and narrow shape. Vertical rock drills are more powerful and in most cases belong to the professional tool.
• By striking force. This indicator characterizes the degree of interaction of the perforator with the material on which it acts. This indicator is measured in joules (J). For example, the impact force of household tools varies from 2.6 to 4.5 J.

• By the number of modes. In addition to the operation of punching holes, the hammer drill may have other capabilities. In particular, drilling, hammering, hammer drilling.
• By type of cartridge. The chuck is a device for securing the working attachment of the hammer drill. As a rule, its appearance determines the size of the nozzle.
• By the speed of wrapping and the speed of blows. The rotational speed of the rock drills ranges from 230 to 2300 rpm. At the same time, the rotation speed of professional models is lower than that of household ones.
• By weight. For many, this indicator is one of the main ones when choosing a hammer drill. Models weighing up to 3 kg are considered light, the weight of heavy ones can be about 12 kg. It is worth noting here the regularity that the greater the power of the perforator, the heavier it is.
• Additional characteristics.For ease of use, many models of rotary hammers are equipped with additional functions, such as: speed change adjustment, reverse travel, soft start, anti-vibration system, switch stopper, wedge protection clutch, Vario-lock (allows you to change the inclination of the working surface).

What to consider when choosing a hammer drill?

Let's start with the type of drill attachment: now only two standards are actually used - the 10-mm SDS-plus shank and the 18-mm SDS-max, which also has additional grooves for transmitting torque and an increased longitudinal stroke. When working with large diameter drills, SDS-max will be preferable, since the chuck and the drill shank itself will wear out more slowly - but, on the other hand, such chucks are used mainly only on not the cheapest professional grade tools.

When working with small diameters, a professional powerful hammer drill will suddenly show itself from a bad side: due to the stiffness of the safety clutch, designed for large drills, the cutting edge will crumble when it collides with stones or reinforcement, and the heavy tool will be more tired - so that a hammer drill with a low impact power, but lightweight and convenient, can become indispensable.

If you are choosing a hammer drill for the home, versatility will not be superfluous: you should take a closer look at models with a quick-release chuck mount, like the bayonets from Bosch or AEG. The ability to quickly install a jaw chuck (rather than using constantly loose chucks with an SDS shank) will be invaluable if you constantly have to change the profile of the tool - and compared to buying a drill and a hammer drill separately, this option will be cheaper, without forcing you to use ersatz substitutes like an impact drill ...

All rotary hammers that we included in the rating of the best are of high quality from manufacturers with a worldwide reputation. The article shows what tasks each of them can cope with - choose the tool that suits your needs. Happy shopping!
