3M 7010327128 Die Grinder Collet 1/4 Inch 300 Series

Product Description

The 3M 7010327128 is a replacement collet designed for 3M 0.3 HP die grinders in the 300 Series product line. The collet accepts a 1/4-inch shank and secures grinding, cutting, or finishing accessories to the grinder spindle during operation. This part is intended for technicians and tradespeople who perform surface preparation, deburring, or material removal work with pneumatic die grinders. Replacing a worn or damaged collet restores proper tool concentricity and helps maintain safe, consistent accessory retention during use.

This collet is suited for industrial and trade environments where 3M 300 Series 0.3 HP die grinders are part of the standard tool inventory. Typical applications include metal fabrication, welding preparation, HVAC sheet metal work, and general mechanical service. The part is sold individually and is intended as a direct replacement to restore tool function without requiring full grinder replacement.

Installation Notes

Collet replacement should be performed by a qualified technician with the grinder disconnected from the air supply before beginning service. Use the appropriate collet wrench and spindle lock to remove the old collet and seat the replacement securely. Do not overtighten the collet nut, as this can damage the collet taper or spindle threads. Verify accessory shank fit and collet engagement before returning the tool to service.
