Keyless Chuck (1/2-inch) 42-66-0200

This is a genuine Milwaukee part, it is sold individually. The chuck is located on the to of the drill where you can add drill bits. The models listed below will show the compatible hammer drills. If your drill's bit retention is suffering, the rotation feels stiff, or the chuck has seized up entirely, a new chuck should fix the problem. Installation is easy with these following steps. You will need to thread the chuck assembly onto the spindle then secure the chuck assembly as tightly as possible (by hand). Then open the chuck to accept the retaining screw and install the retaining screw. Secure the screw with a Phillips screwdriver. The screw is reverse threaded requiring counter clockwise rotation to secure.
