Milwaukee 1/2 in. Keyless Chuck
Model Number: 42-66-2902
The Milwaukee 42-66-2902 is a genuine OEM 1/2 in. Keyless Chuck for use in compatible Milwaukee drills. The keyless chuck is the three-jaw bit retention system that accepts drill bits and accessories up to 1/2 in. shank diameter — allowing the operator to tighten and release the jaws by hand rotation of the outer sleeve without a chuck key. The chuck must maintain concentricity across its full capacity range from small bits up to the maximum 1/2 in. shank to minimize runout and ensure accurate hole placement. A worn, slipping, or damaged keyless chuck that can no longer grip bit shanks securely or maintain concentricity requires replacement to restore accurate, secure bit retention in the drill it serves.
Using a genuine Milwaukee OEM 1/2 in. keyless chuck ensures the correct mounting thread, jaw capacity, and concentricity 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.
