	Hammer Drills The hammer drill (also called an impact drill) is a variation of the power drill and is designed for drilling holes in brick, cement block, concrete, wood, metal, and resin plate. The hammer drill gets its name from the fact that in addition to rotating the drill bit, it also "hammers" it in. This helps to penetrate hard surfaces such as cement faster.
