A drill with a pistol grip handle is usually compact and lightweight, making the tool suitable for a large variety of applications and easy to use.
A long cable ensures more freedom of movement.
When covered under the manufacturer’s warranty it is possible to get a replacement in the case of a malfunction.
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.
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 amperage is the strength of an electric current and it is measured in amperes (amps).
