Chuck Assembly 42-66-0900

This drill chuck assembly is specially designed for use with Milwaukee compact driver drills. Its purpose is to secure drill bits. It is a keyless chuck that allows for quick and easy bit swap. The ratcheting action clicks the jaws tightly into place for reduced bit slippage. 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. Please note the screw used to secure this chuck it is sold separately. To complete this simple repair you should only need a screwdriver. • Make sure the unit is unplugged • Remove the chuck retaining screw • Remove old chuck and secure the new one • Tighten the chuck retaining screw • Test the tool
