Milwaukee 3/8 in. Chuck — 1/2-20 Spindle
Model Number: 48-66-0806
The Milwaukee 48-66-0806 is a genuine OEM 3/8 in. Chuck with a 1/2-20 spindle thread for use in compatible Milwaukee 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 up to 3/8 in. — securing them to the output spindle during drilling and driving operations. The 1/2-20 spindle thread designation identifies the thread specification the chuck uses to mount onto the drill's output spindle. Milwaukee uses a chuck retaining screw inside the chuck to lock the assembly in place after threading it onto the spindle. A chuck that no longer grips bits securely, has seized jaws, or has damaged threads requires replacement to restore reliable bit retention and safe drill operation.
Using a genuine Milwaukee OEM chuck ensures the correct 1/2-20 spindle thread, 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.
