The main function of impact drill

Impact drills can be used on natural stone or concrete. They are universal, and because they can be used in both "single drill" and "impact drill" modes, they are a worthy choice of basic power tools for professionals and do-it-yourselfers. Electric hammers work by spinning and beating. The individual thumping force is very high, and with a thumping frequency of 1000 to 3000 per minute, it can generate significant force. Compared to impact drills, electric hammers require minimal pressure to drill into hard materials such as stone and concrete; especially relatively hard concrete. Electric drills only have a rotation mode, and are especially suitable for drilling holes in materials that require very little force, such as cork, metal, brick, ceramic tile, etc. Impact drills rely on rotation and impact to work. A single shock is very slight, but a frequency of more than 40,000 shocks per minute produces a continuous force.
