3M 7100142324 Die Grinder 1 Hp 8000 Rpm 1/4 Inch Collet

Product Description

The 3M 7100142324 is a straight-shaft pneumatic die grinder built for grinding, deburring, and surface preparation in industrial and trade environments. It delivers 1 horsepower and spins at 8,000 RPM, making it well suited for material removal on metal, weld seams, and hard-to-reach surfaces. The 1/4 inch collet accepts a wide range of mounted points, carbide burrs, and grinding bits. Licensed mechanics, fabricators, and maintenance technicians are the primary installers and operators of this tool in shop and field settings.

This die grinder fits into applications where a compact, straight-shaft profile is required for access to confined workspaces. Typical use cases include weld cleanup, porting, deburring metal castings, and surface conditioning. The straight-shaft configuration provides a low-profile grip angle suited for inline work on flat or gently curved surfaces. It is sold as a single unit and is appropriate for production floors, fabrication shops, and field maintenance crews.
