Power – so important with a cordless drill – consists of speed and torque, and it’s important to compare these values. More torque settings provide greater control when driving screws for instance. For combi drills the hammer function (measured in beats per minute) needs to be compared too.
Don’t forget the chuck. Larger cordless drills come with 13mm chucks whilst 10mm is the norm on drill drivers. Most cordless drills feature a keyless chuck.
