The chuck is the bit retention mechanism at the front of the drill that grips drill bits, driver bits, and other round-shank accessories securing them to the output spindle during drilling and driving operations. Milwaukee uses a chuck retaining screw inside the chuck to secure the assembly to the spindle the chuck threads onto the spindle and the retaining screw (typically left-hand thread) locks it in place. A chuck that no longer grips bits securely, has seized or damaged jaws, or has stripped spindle threads requires replacement to restore reliable bit retention and safe drill operation.Using a genuine Milwaukee OEM replacement chuck ensures the correct spindle thread specification, jaw capacity, and chuck body dimensions for the drill it serves.
