A reversible drill can alter its rotations from a clockwise direction to a counter clockwise direction, a feature that makes it suitable for both drilling and driving.
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 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.
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).
