Milwaukee Router Collet 1/4 in.
Model Number: 48-66-0985
The Milwaukee 48-66-0985 is a genuine OEM 1/4 in. Router Collet replacement for compatible Milwaukee routers — the precision-machined collet that clamps around the router bit's 1/4 in. shank inside the router's collet nut assembly to grip and retain the bit concentrically during routing operations. The router collet is the critical interface between the router spindle and the router bit — collet condition directly determines the bit's runout, which in turn determines cut quality, surface finish, bit vibration, and the loads imposed on the bit shank and collet assembly during routing. A worn 1/4 in. collet with grooves, scoring, bell-mouthing at the shank entry, or reduced gripping force from fatigued spring slots causes excessive bit runout that degrades cut quality, accelerates bit wear, and can result in bit ejection from the router if gripping force is insufficient to hold the bit against cutting forces at routing speed.
The 1/4 in. collet specification accommodates the 1/4 in. shank diameter that is standard on smaller-profile router bits, straight bits, edge profiles, and the majority of router bits used in general woodworking and trim routing applications where 1/4 in. shank bits provide the most economical and widely available bit selection. Replacing a worn or damaged 1/4 in. collet with a genuine Milwaukee OEM part ensures the correct collet body dimensions, spring slot geometry, and surface finish for accurate bit concentricity and uniform clamping force distribution. Always verify compatibility with your specific Milwaukee router model number and serial number at milwaukeetool.com before ordering — collet specifications vary by router model.
