Power and torque

Power is usually measured in watts (W) and torque in newton meters (Nm). The higher the values ​​of these parameters, the more difficult and complex work the tool can perform. For most home craftsmen, a hammer drill with a power of 600-1200 W and a torque of 40-60 Nm is sufficient. For professional use, it is better to choose models with higher performance. For example, some models from [Quanzhiguang](https://www.gzqzg.ru/) offer torque up to 120 Nm, which provides excellent performance.

Battery type and capacity

The battery is the key elementcordless hammer drill. There are different types of batteries: NiCd, NiMH and Li-ion. Lithium-ion batteries (Li-ion) are the most modern and preferred, as they have high energy density, long service life and do not have the “crying battery” effect. Battery capacity is measured in ampere hours (Ah). The higher the capacity, the longer the tool can work without recharging. For long-term operation, it is better to choose models with batteries with a capacity of 4-5 Ah or more. It is also important to consider the battery charging time - this can vary from 30 minutes to several hours.

Speed adjustment and shock mode

Speed adjustment allows you to choose the optimal mode for different types of work. For drilling lightweight materials, you can use a low speed, and for chiselling concrete, you can use a high speed. The impact mode is a key feature of the hammer drill, which provides impacts on the material, making drilling and chiselling easier. Some models have impact force adjustment, which allows you to more accurately control the work process. It is convenient if the power button is locked - this prevents the tool from being turned on accidentally.
