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.
Drills with LED light provide a constant light source.
The device comes with its own special case or pouch, which is useful for safe transportation.
The chuck holds the drill bits or other rotary tools and its diameter determines the types of bits and tools that the drill can use. A larger chuck is compatible with a wider range of bits and tools.
Higher speeds work better for drilling holes in certain types of material, such as steel, aluminium, concrete, etc. The drill speed is measured in rotations per minute (rpm) 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 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.
The amperage is the strength of an electric current and it is measured in amperes (amps).
