Milwaukee Replacement Chuck
Model Number: 48-66-1481
The Milwaukee 48-66-1481 is a genuine OEM Replacement Chuck for compatible Milwaukee drills — the keyless chuck that interfaces between the drill's spindle and the drill bit or accessory, providing the bit gripping and retention needed for accurate, safe drilling operations. The chuck is one of the most functionally critical components on any drill — it determines bit concentricity, gripping security, and the runout that directly affects hole quality and bit life. A worn chuck with excessive jaw play, slipping action, or damaged internal mechanisms produces inaccurate holes, allows bit slippage during drilling that damages workpieces, and makes bit changes unreliable. Replacing a worn chuck with this genuine Milwaukee OEM replacement restores the original chuck performance specifications for concentricity, jaw engagement reliability, and secure bit retention through the full range of drilling operations the tool is designed for.
Milwaukee OEM chucks are manufactured to the correct spindle thread specification, jaw capacity range, and internal mechanism geometry for compatible Milwaukee drill models — using a non-OEM chuck with an incorrect spindle thread pitch or diameter creates an unsafe chuck seating condition that risks chuck loosening or separation during drilling. The keyless design allows tool-free bit installation and removal for the fast bit change convenience that Milwaukee drills are designed to provide. Always verify your specific Milwaukee drill model number and serial number at milwaukeetool.com before ordering a replacement chuck, as chuck specifications vary between Milwaukee drill model families and production revisions.
