What is a hammer drill and why you need this device?
A hammer drill is a power tool that can drill holes in different materials, depending on which Chuck used and depending on the location at which the holes to drill.
While a normal drill bit only by rotational movements tried to penetrate deeper into a material and thereby with softer materials such as wood holes Incurred are required for mineral materials such as stone and concrete more strength. This provides the hammer blow by small movements that crush the material. Depending on the driving energy can still differentiate between electric and pneumatic hammers.
