Milwaukee 1/2 in. Steel Chuck
Model Number: 42-66-0035
The Milwaukee 42-66-0035 is a genuine OEM 1/2 in. Steel Chuck for use in compatible Milwaukee drills and hammer drills. The steel chuck is the three-jaw clamping device at the output of the drill that accepts drill bits, driver bits, and other accessories — using a steel-bodied keyless or keyed mechanism to grip the bit shank concentrically for low run-out drilling and driving. The steel body construction provides maximum durability and impact resistance for hammer drill applications where the chuck is subjected to continuous percussive loading. A chuck with worn or damaged jaws that allows bits to slip, wobble, or cannot be tightened securely requires replacement to restore accurate, reliable bit retention.
Using a genuine Milwaukee OEM steel chuck ensures the correct jaw range, spindle thread specification, and run-out tolerance for the tool 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.
