Rotation speed

The speed of rotation of the working nozzle provided by the tool.

If a single number is indicated in this paragraph (for example, 1800), it can be either a standard, constant, or maximum rotation speed. This refers to the maximum speed if the tool has more than one speed (see "Number of speeds") and/or a speed controller (see "Functions"). In turn, two or three numbers through an oblique line (for example, 1100/2300/3400) are indicated only for models that have the corresponding number of individual speeds. Each of these numbers indicates the standard (and in the presence of a speed controller — the maximum) number of revolutions at one of the speeds.

Anyway, when choosing a tool by the number of revolutions, it is worth considering both its general type (see "Device") and the specifics of the intended work. Detailed recommendations on this matter are quite extensive, it makes no sense to give them in full here — it is better to turn to special sources. We note only a few general points. So, high -speed drills nowadays are considered to be drills capable of delivering more than 3000 rpm. In general, high speed contributes to productivity, but there is also a downside: increasing the speed (for the same power) reduces torque — accordingly, the efficiency of working with stubborn materials and large diameter nozzles decreases. Therefore, it makes sense to specifically look for a "high-speed" tool only if speed is of key impor...tance; it doesn’t hurt to make sure that the model you choose can provide the required efficiency and torque.

Chuck diameter

The nominal diameter of the chuck supplied with the tool.

This size is indicated by the maximum diameter of the drill (or bit shank) that can be installed in the fixture. There are several standard sizes; the most popular nowadays are the 10 mm cartridge and the 13 mm cartridge ; drills with a 16 mm chuck are noticeably less common, as well as miniature mounts less than 10 mm(usually 8 mm or 6 mm).

The larger the drill, the more power is required for its efficient use; accordingly, larger cartridges are characteristic of heavier and more powerful tools. At the same time, it is quite possible to install a smaller cartridge on the drill, if the possibility of replacement is technically provided for at all. But the possibility of working with larger fasteners (and drills for them) should be clarified separately: not every tool has enough power for this.
