3M 7100143021 Ceramic Cartridge Roll 60 Grit

Product Description

The 3M 7100143021 is a ceramic grain cartridge roll designed for aggressive material removal in grinding and finishing applications. Built on an X-weight cloth backing, it delivers durability under the heat and pressure typical of industrial grinding work. The resin bond system resists heat buildup, and an integrated grinding aid promotes cooler cutting to extend abrasive life and reduce workpiece discoloration. This cartridge roll measures 0.5 inches in diameter by 1.5 inches in length with a 0.125-inch arbor hole. It is used by metalworkers, fabricators, and maintenance trades working with die grinders and cartridge roll mandrels.

This cartridge roll is suited for deburring, blending, and stock removal on metal surfaces in both production and maintenance environments. The 60-grit designation places it in the medium-to-coarse cutting range, making it appropriate for initial grinding passes, weld blending, and surface prep before finer finishing steps. It is sold by the roll with a minimum order quantity of 100 units, making it a fit for shop-level consumption.
