3M 7100106791 Die Grinder 1 Hp 18000 Rpm 1/4 Inch Collet

Product Description

The 3M 7100106791 is a straight-shaft pneumatic die grinder built for professional metalworking, deburring, grinding, and surface preparation tasks in trade and industrial environments. Rated at 1 horsepower and spinning at 18,000 RPM, this tool delivers consistent rotational speed for extended work cycles. The 1/4-inch collet accepts a wide range of standard grinding bits, mounted points, and carbide burrs. At 3.86 pounds, the tool is compact enough for overhead and confined-space work without causing excessive fatigue during sustained use. It is suited for fabricators, pipefitters, machinists, and maintenance technicians who require a reliable inline grinder for daily production tasks.

This die grinder is designed for use in metal fabrication shops, industrial maintenance environments, and mechanical service applications. The straight-shaft configuration makes it well suited for inline grinding tasks where a pencil-style grip provides better control. It is commonly used on steel, aluminum, and other metals for weld cleanup, port matching, and precision material removal. The 1/4-inch collet is the most common size for rotary tool accessories in the trade, giving technicians broad accessory compatibility across manufacturers.
