Power consumption

Power consumed when operating an electric tool (see “Type”). Essentially, this is the power of the electric motor installed in the tool.

This indicator primarily determines electricity consumption and connection requirements. Thus, devices with a power of up to 3.5 kW can operate from a regular 230 V outlet; at higher values, as a rule, a connection to a 400 V network is required.

Also, based on power consumption, the general capabilities of tools are often assessed and compared - operating speed, ability to cope with hard materials, etc. Technically, this is not entirely true, since such characteristics depend not on the consumed, but on the useful power (see above). However, the latter is indicated relatively rarely in the characteristics, and the difference in energy consumption most often more or less corresponds to the difference in output power. So it is quite possible to say that the higher the power consumption, the “stronger” the tool as a whole, the greater the cutting depth and operating speed it can provide, and the better suited for hard materials.

Disc/cutter size

The diameter of the blade/cutter for which the tool is designed.

A larger blade can provide greater depth of cut, but requires a more powerful motor. Accordingly, this parameter is directly related to the power and performance of the tool: the more powerful and heavier the unit, the usually larger the diameter of the working element in it. Note that some models allow the installation of cutters / discs and a smaller diameter than the standard one, but you cannot install a larger work item.

Rotation speed

The maximum speed of rotation of the disk / cutter provided by the tool.

The higher the speed, the higher the speed of the cutting edge relative to the material, the higher the processing speed and the more accurate the cut is. On the other hand, as the speed increases, the torque decreases. So for the same blade/cutter diameter, higher RPMs will be beneficial on relatively soft materials, while a slower tool will be better for hard and stubborn materials.

Noise level

Approximate noise level produced by the instrument during operation (actual volume may vary depending on performance).

The lower the noise, the more comfortable the use of the tool, the easier it is to work with it without headphones or other noise protection equipment. It is easiest to evaluate a specific volume level using comparative tables. In general, wall chasers and jointers are quite noisy equipment — in most models, the volume exceeds 90 dB (loudness comparable to the sound of a moving freight car at 7 m), and in the most noisy this figure reaches 118 – 119 dB, which is only slightly below the human pain threshold . If the volume is more than 100 dB, it is highly recommended to use protective headphones or earplugs.
