Brushless is virtually the norm in professional cordless power tools and that’s due to how robust these motors are and their improved efficiency.

Dewalt has gone even further with the motor on the DCD991, making it bigger which results in a 34% increase in power.


The more gears a drill has, the greater the control you have over the RPM of the chuck. This is ideal for avoiding over-driving a screw or for those times when just need more power to the chuck.


Knocks and bumps are expected on the job site and these can result in damage and corrosion to the chuck of your drill. The DCD991’s chuck is a durable nitro-carburised metal. During the manufacturing process, the metal used in the chuck is infused with nitrogen and carbon. This makes the chuck stronger and helps to prevent corrosion.

And the carbide inserts mean the chuck’s jaws have amazing bit gripping strength.
