Impact drills can be used on natural stone or concrete. They are versatile because they can be used in either "single drill" or "impact drill" mode, making them a worthy choice of basic power tools for both professionals and do-it-yourselfers. An electric hammer works by spinning and hammering. The individual hammering force is very high and has a hammering frequency of 1000 to 3000 per minute, which can produce significant force.

Compared with a hammer drill, an electric hammer requires minimal pressure to drill into hard materials such as stone and concrete. Especially concrete, which is relatively hard. The electric drill only has the rotating mode, especially suitable for drilling on the material that requires little force, such as cork, metal, brick, tile, etc. A hammer drill works by rotation and impact. A single shock is very slight, but a frequency of more than 40,000 shocks per minute can produce a continuous force.
