3M 7100075513 Extended Die Grinder 0.3 Hp 25000 Rpm

Product Description

The 3M 7100075513 is a pneumatic straight-shaft die grinder with a 3-inch extended reach, designed for polishing, buffing, shaping, and deburring in confined or hard-to-access areas. Running at 25,000 RPM and rated at 0.3 HP, it delivers consistent rotational speed for precision material removal and surface finishing tasks. The tool features rear exhaust to direct airflow away from the work surface and operator. It ships complete with a 1/4-inch collet, a 1/8-inch collet insert, a 1/4-inch to 1/8-inch reduction bushing, and two wrenches, making it ready to use out of the box.

This lightweight pneumatic die grinder suits fabrication shops, maintenance facilities, automotive body work, and general metalworking environments where operators need to reach recessed welds, internal cavities, or tight clearances. The 3-inch shaft extension sets it apart from standard-length die grinders and reduces the need for awkward tool positioning in deep or obstructed work zones. It is typically used by machinists, fabricators, and maintenance technicians working with air-supply systems capable of meeting the tool's pneumatic requirements.
