3M 7100075511 Extended Die Grinder 0.3 Hp 18000 Rpm

Product Description

The 3M 7100075511 is a pneumatic straight-shaft die grinder with a 3-inch extended neck, designed to reach confined or obstructed work areas that standard-length tools cannot access. Rated at 0.3 HP and 18,000 RPM, this lightweight air-powered grinder handles polishing, buffing, shaping, and deburring tasks efficiently. Rear exhaust keeps airflow directed away from the work surface and the operator. The tool ships 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, so it is ready for use out of the box.

This die grinder is suited for metalworking, fabrication, and finishing applications where access is limited by surrounding structure, flanges, or tight assemblies. It is commonly used in automotive, HVAC, and general mechanical service environments. The extended shaft provides clearance without requiring a specialty attachment, making it a practical choice for technicians who regularly work in cramped or deep-set areas on equipment and assemblies.
