Milwaukee 1/2 in. Chuck 42mm
Model Number: 48-66-1355
The Milwaukee 48-66-1355 is a genuine OEM 1/2 in. Keyed or Keyless Chuck with 42mm collar for compatible Milwaukee corded or cordless drills — a replacement chuck assembly for the specific Milwaukee drill model this chuck is designed for, restoring full bit retention and concentricity when the original chuck develops runout, loses jaw clamping force, or is damaged from use. The 42mm collar dimension specifies the outside diameter of the chuck body that interfaces with the drill's chuck mounting collar — this dimension is specific to the drill models that use the 42mm standard collar for chuck mounting, and is distinct from smaller-collar chucks used on compact and mid-size drills. The 1/2 in. capacity covers the full range of standard drill bits, hole saw arbors, and accessories up to 1/2 in. shank for the heavier-duty drilling applications these 42mm-collar drills typically support.
Using a genuine Milwaukee OEM chuck ensures the correct spindle thread, jaw geometry, collar dimension, and bite depth for the specific Milwaukee drill model — a chuck with incorrect spindle thread or collar dimension will not mount correctly on the drill. Always verify your specific Milwaukee drill model number and serial number at milwaukeetool.com before ordering chuck components, as chuck specifications vary between Milwaukee drill models and the 42mm collar specification is shared across specific Milwaukee drill models only.
