Glossary
Real power
The useful power of the tool is the maximum power that it can deliver to the working nozzle. This power is always less than the power consumed (see below), since part of the electricity inevitably goes to heat and friction in the tool mechanisms. In addition, this parameter is not given for every model, often information in the characteristics is limited to power consumption. Nevertheless, the actual capabilities of the tool directly depend on the net power: the higher it is, the greater the speed and/or torque this model is able to develop, the easier it is for it to cope with tasks that require high efforts. So, to compare different devices with each other, it is best to use this parameter (of course, you can only compare models of the same type or similar in type).
Also note that high working power is not always an advantage: it accordingly affects the dimensions, weight and price of the tool, while in fact high speeds and efforts are not always necessary. Detailed recommendations on the optimal values for different tools and different types of work can be found in special sources.

Torque
Torque is the maximum force with which this model is capable of turning the working nozzle.
Higher torque gives more options, it allows you to cope with complex tasks such as drilling in hard materials, unscrewing stuck screws and nuts, etc. On the other hand, a lot of force requires corresponding power — and this, in turn, affects the dimensions , weight and cost of the tool itself, and also puts forward increased power requirements (mains power, battery capacity or pressure / compressor performance). And for some tasks, excessive torque is basically unacceptable, so for maximum versatility, it is desirable to have torque control — and this affects the cost even more. And the more steps, the more optimally you can configure the tool to perform a particular type of work. So the general rule is this: when choosing, it is worth considering the specifics of the planned work, and not chasing the greatest working effort.
Detailed recommendations on choosing the optimal torque for different types of tools (see "Device") can be found in special sources. Here we note that it is of key importance primarily for screwdrivers, although it is also given for other types of tools. At the same time, in the “weakest” models, the maximum working force does not exceed 15 Nm, in the most powerful ones it is more than 150 Nm.
