ChuckModel Number: 48-66-1540The Milwaukee 48-66-1540 is a genuine OEM 3/8 in. Chuck for use in compatible Milwaukee drills and driver-drills. 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. The 3/8 in. capacity is suited to compact drills and lighter-duty driver-drills where a smaller chuck diameter is specified. Milwaukee uses a chuck retaining screw inside the chuck to secure the assembly to the spindle. A chuck that no longer grips bits securely, has seized jaws, or has damaged threads requires replacement to restore bit retention and safe drill operation.Using a genuine Milwaukee OEM chuck ensures the correct spindle thread specification, jaw capacity, and chuck body dimensions for the drill it serves.
