Also Known as hammer drill, chipping hammer, concrete breaker, hand-held drill, rotary hammer, hilti gun, demolition hammer

Hammer drills are well suited for drilling holes in masonry or stone. They are also used to drill holes in concrete footings to pin concrete wall forms and to drill holes in concrete floors to pin wall framing. The hammering action helps to break up the masonry so that it can be removed by the drill bit’s flutes.
