Product Description

The 3M 7010308318 is a replacement collet for the 3M 0.3 HP Die Grinder 300 Series. The collet accepts 1/8-inch shank accessories and secures them in the grinder spindle during operation. This part is designed for tradespeople and maintenance professionals who service 3M pneumatic die grinders in industrial, fabrication, and mechanical shop environments. Replacing a worn or damaged collet restores proper tool-bit retention and helps maintain safe, consistent performance during grinding, deburring, and surface-finishing tasks.

Typical install scenarios include maintenance shops, manufacturing facilities, and field service environments where 3M die grinders are part of the standard tool inventory.
