Removing a Cordless Drill Chuck

A lot of cordless drills require the removal of the chuck for repairs, especially when repairing the gearbox or torque selector collar. This little guide should help. Please remember that these instructions only work for threaded-on chucks and not taper-fit chucks (almost all cordless drills have threaded chuck spindles). Use caution and common sense.

Remove the chuck screw

In many drills there is a small screw deep inside the jaws of the chuck. This screw helps hold the chuck onto the spindle during operation, preventing it from spinning off. Check to see if you have a screw inside your chuck’s jaws. Depending on the brand and model of your drill, you may have to use an allen key, torx driver, or a flat-head screwdriver to remove the screw. The most important thing to remember is this: the chuck screw is reverse-thread. You will have to spin the screw clockwise to remove it. This reverse threading helps to act against the torque of the drill and keep the screw tightly connected.
