The device comes with its own special case or pouch, which is useful for safe transportation.
A rotary hammer drill delivers a much stronger blow to the bit than a hammer drill due to the built-in piston system. The additional force is unnecessary for most home improvement tasks unless you are looking to reinforce concrete with rebar.
When covered under the manufacturer’s warranty it is possible to get a replacement in the case of a malfunction.
A keyless chuck drill enables you to change out drill bits rapidly without having to use any special keys.
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.
A tool/machine with a higher voltage produces more power.
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.
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.
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).
