Max. hole saw ⌀

The maximum tool diameter that can be used with a rotary hammer when drilling with a hollow core. Crowns are used to create holes of large diameter (from 40 mm) in hard materials such as reinforced concrete and stone. See "Maximum drilling diameter in wood" for details on the maximum diameter.

Compatible batteries

The name of the battery that is compatible with the device. It helps to buy a spare or find a suitable one in case of a breakdown of the main one.

In box

Additional handle. The presence of an additional front handle on the hammer drill, usually located at the base of the chuck. This handle can be non-removable or removable, rigidly fixed or movable. Holding two handles with two hands is much more convenient than holding one and the body, as it allows for optimal distribution of the load on the hands; this is especially important during long-term work and processing of “heavy” materials.

Depth gauge. A device that allows you to make holes of a strictly defined depth in one go, without constant measurements and without the risk of drilling deeper than necessary. Usually looks like a rod fixed to the body of the hammer drill parallel to the working tool. When used, this rod extends to such a length that when the desired depth is reached, it rests against the surface of the material being processed, preventing the drill from moving further.

Chisel. Complete attachment for impact work with a hammer drill in the manner of chasing, leveling hard surfaces, chipping tiles, bricks, concrete, etc. Different types of chisels are produced for different tasks — flat, blade, groove, crushing peaks with a sharp tip.

Boring bit. The presence of Boring bit in the delivery set of tool designed for processing various hard materials by drilling with impact. Buying such a s...et eliminates the need to look for a drill separately, but the characteristics of the complete attachment must be clarified before purchasing, since they may not meet the buyer's requirements.

Charger. The presence of a charging unit in the kit allows you to charge batteries. Accordingly, for models with batteries, this accessory is necessary to power the battery. However, there are models without a charger. And hammer drills with it can differ in the model of the charger, the name of which will allow you to learn more about its characteristics and, if necessary or as needed (breakdown), buy a similar one.

Case included. The delivery set includes a special case that facilitates storage and transportation: it provides protection from impacts and adverse conditions (moisture, frost), is equipped with a special handle for carrying, in addition, in the case, along with the hammer drill itself, a set of working tools, replacement cartridges, etc. can be placed.

Dust collector. The hammer drill comes with a special dust collector. As the name suggests, it is designed to collect dust generated during operation, which could otherwise cause significant inconvenience. It usually looks like a bag or container attached to the body; it can be either replaceable (thrown away with the collected garbage) or permanent. The dust collector slightly increases the weight and dimensions of the hammer drill, but it can be removed if necessary.

Weight

The weight of a fully assembled rotary hammer (in the case of battery power, with a standard battery installed). Unlike many other types of equipment, in the case of rotary hammers, light weight is far from always an advantage. So, heavy models are better suited for professional use — they are less prone to vibrations and, usually, are stronger, which is important when working with difficult-to-cut materials for a long time. But for small, simple works of short duration, a lot of weight is not required, and in this case, light models are useful, which do not require significant effort to hold on weight.
