A hammer drill contains a hammer clutch or a hammer-like mechanism which provides a circular rotation and a forward driving force. A hammer drill is capable of performing heavy-duty tasks, but it can also be used as a regular power drill.
The device comes with its own special case or pouch, which is useful for safe transportation.
A long cable ensures more freedom of movement.
A tool/machine with a higher voltage produces more power.
The hammering action provides short, rapid hammer thrusts which make drilling faster and easier. The hammering action is measured in blows/beats per minute (bpm) when the drill has no-load.
A drill with variable speed allows you to switch between low and high speeds, giving you the possibility to take on a wider range of tasks.
The amperage is the strength of an electric current and it is measured in amperes (amps).
