Product Description

The 3M 7100075510 is a straight-shaft pneumatic die grinder rated at 0.3 HP and 18,000 RPM, built for polishing, buffing, shaping, and deburring in production and maintenance environments. The tool features rear exhaust to direct airflow away from the work surface and 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. 3M Gripping Material is integrated into the handle to dampen vibration and improve control during extended use. Weighing 3.26 pounds, it is a compact, handheld pneumatic tool suited for technicians and fabricators who need precise material removal at high speed.

This die grinder is well suited for light-duty to medium-duty shop tasks including deburring metal castings, shaping composite materials, and detail polishing on finished surfaces. Its straight-shaft design allows direct access to confined or recessed work areas. The included collet set gives operators flexibility to run both 1/4-inch and 1/8-inch shank accessories without additional tooling purchases. The tool is appropriate for automotive, HVAC fabrication, plumbing rough-in, and general metalworking applications where a compact pneumatic rotary tool is needed.
