3M 7100118838 Ceramic Cartridge Roll 80 Grit 0.75x1.5x0.25 in

Product Description

The 3M 7100118838 is a ceramic grain cartridge roll designed for aggressive material removal and consistent finishing in grinding and blending applications. Built on an X-weight cloth backing with resin bond construction, it delivers durability under high-pressure use and resists heat buildup during extended operation. The integrated grinding aid promotes cooler cutting, which helps extend abrasive life and reduces heat-related workpiece discoloration. At 80 grit, this roll is suited for moderate stock removal and surface preparation. The compact 0.75 inches x 1.5 inches x 0.25 inches roll dimensions make it compatible with mandrel-style rotary tools and die grinders commonly used in metal fabrication and finishing trades.

This cartridge roll is used in metalworking, fabrication, and finishing operations where a small-diameter abrasive is required to reach confined areas, inside diameters, or contoured surfaces. It is appropriate for use on ferrous metals, stainless steel, and similar hard materials. Typical users include metal fabricators, machinists, maintenance technicians, and industrial finishing professionals working with die grinders or rotary tool setups.
