A Hammer drill (as distinct from a rotary hammer drill) is a rotary drill with a hammering action. The hammering action provides a short, rapid hammer thrust to pulverize relatively brittle material and provide quicker drilling with less effort. A hammer drill is perfect for drilling holes in masonry or stone. It is 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 hammer drill is similar to a standard electric drill, with the exception that it is provided with a hammer action for drilling masonry. The hammer action may be engaged or disengaged as required. |
