Milwaukee 3/8 in. Steel Chuck
Model Number: 42-66-0100
The Milwaukee 42-66-0100 is a genuine OEM 3/8 in. Steel 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. Steel chuck construction provides maximum durability and jaw grip strength for demanding applications. 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 jaws, or has damaged threads requires replacement to restore bit retention and safe drill operation.
Using a genuine Milwaukee OEM steel chuck ensures the correct spindle thread specification, jaw capacity, and chuck body dimensions for the drill it serves. Always verify your catalog number and serial number on Milwaukee's website before ordering to confirm this is the correct chuck for your specific unit.
