Product Description

The MILWAUKEE TOOL 48-66-2486 is a 1/8 inch collet nut assembly designed for use with Milwaukee M12 FUEL die grinders. This replacement collet and nut assembly secures 1/8 inch shank rotary accessories at the spindle, maintaining proper tool retention during high-speed grinding, deburring, and finishing operations. Rated to 24,500 RPM, it is built for the rotational demands of compact cordless die grinder platforms. The assembly ships as a single unit and is a direct OEM-style replacement for worn or damaged collet hardware. It is installed by mechanics, metal fabricators, and HVAC technicians who use M12 FUEL die grinder tooling in tight-access applications.

This collet nut assembly fits the Milwaukee M12 FUEL Right Angle and Straight Die Grinder models. It is suited for light-duty precision work where 1/8 inch shank bits, carbide burrs, mounted points, and abrasive accessories are used.

Installation Notes

Power off and remove the M12 battery pack before servicing the collet assembly. Use the spindle lock and appropriate collet wrench to seat the collet nut to hand-tight plus firm wrench engagement — do not overtighten. Verify the accessory shank is fully seated in the collet before operating. Inspect the collet and nut for wear or damage at each accessory change.
