3M 7010294689 Straight Cartridge Roll 320 Grit 1/2 in

Product Description

The 3M 7010294689 is a straight cartridge roll designed for precision deburring, blending, and finishing on metal and other hard surfaces. It uses aluminum oxide abrasive on a cloth backing, delivering consistent cut and finish throughout the life of the roll. At 320 grit, this is a very fine grade product suited for final-stage surface prep and light material removal. The 0.5-inch diameter and straight configuration make it compatible with mandrel-driven rotary tools and die grinders at speeds up to 24,000 RPM. It is primarily used by metalworking professionals, machinists, and fabricators who require controlled, repeatable finishing in tight or contoured areas.

This cartridge roll is well suited for interior bore finishing, contoured surface blending, and weld seam cleanup in both production and maintenance environments. Its cloth backing provides flexibility to conform to curved and irregular workpiece profiles. Applications include aerospace, automotive, and general metal fabrication shops where fine surface finish requirements must be consistently met. The small diameter allows access to areas that larger abrasive tools cannot reach.
