Milwaukee Collet Nut for M12 Rotary Tool 2460-20
Model Number: 44-40-0770
The Milwaukee 44-40-0770 is a genuine OEM Collet Nut for the Milwaukee M12 Rotary Tool 2460-20, 2460-21, and 2460-059. The collet nut is the threaded steel nut that screws onto the rotary tool's spindle over the collet — when tightened, it compresses the collet around the accessory shank to lock bits, burrs, grinding stones, cut-off wheels, and other 1/8 in. shank accessories securely in place during cutting, grinding, carving, engraving, and polishing operations. A stripped, cracked, or cross-threaded collet nut that no longer tightens correctly or allows the collet to loosen during use requires replacement to restore safe and secure accessory retention on the 2460-20. The collet nut features a knurled outer diameter for improved grip when tightening and loosening by hand, and the collet wrench slots allow tightening with the included spindle wrench to achieve correct clamping torque.
The 44-40-0770 collet nut is used together with the 1/8 in. collet 42-77-0400 — if the collet itself is also worn or damaged, both the collet and nut should be replaced together to ensure a secure and accurate accessory clamping system. Always verify your rotary tool's model number before ordering to confirm the 44-40-0770 is the correct collet nut for your specific unit.
