Milwaukee 7/16 in. Hex Chuck Assembly
Model Number: 42-66-0050
The Milwaukee 42-66-0050 is a genuine OEM 7/16 in. Hex Chuck Assembly for use in compatible Milwaukee screwguns and drywall tools. The 7/16 in. hex chuck is the quick-change accessory holder at the output of the screwgun — the sleeve and retention mechanism that accepts 1/4 in. hex shank screwgun bits and holds them securely during high-speed driving operation. The 7/16 in. designation describes the hex socket opening that accepts the shank. Screwgun chucks experience rapid bit changes and high-cycle loading and must maintain reliable bit retention and accurate bit centering throughout their service life. A worn, cracked, or failed chuck assembly that causes bits to wobble, slip, or cannot be reliably retained requires replacement to restore accurate, reliable bit drive.
Using a genuine Milwaukee OEM 7/16 in. hex chuck assembly ensures the correct retention geometry, hex bore dimensions, and output interface for the screwgun 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.
