3M 7100080025 Straight Cartridge Roll 60 Grit 1/4 in

Product Description

The 3M 7100080025 is a straight cartridge roll designed for precision grinding, deburring, and surface blending in metal fabrication and finishing applications. Built with aluminum oxide abrasive on a cloth backing, this roll delivers consistent stock removal at a medium grade (60 grit). The 0.25-inch diameter profile fits standard mandrel-driven rotary tools and die grinders, making it a dependable choice for technicians working in tight bores, contoured surfaces, and hard-to-reach weld zones. It is rated to a maximum spindle speed of 24,000 RPM, suiting high-speed pneumatic and electric rotary tools common in trade shop environments.

This cartridge roll is suited for use on ferrous and non-ferrous metals in both production and maintenance settings. It performs well in applications such as weld blending, bore finishing, edge chamfering, and die work. The cloth backing provides flexibility to conform to curved or irregular surfaces without tearing under load. Trade professionals in fabrication, pipefitting, tool and die, and industrial maintenance will find this roll appropriate for controlled material removal where a medium abrasive cut is required.
