The 3M 7100085782 is an aluminum oxide cartridge roll designed for precision grinding, deburring, and surface blending on metal and other hard materials. Built on an X-weight cloth backing, it offers the durability needed for demanding stock removal tasks. The abrasive is resin bonded, which provides heat resistance and helps the grain stay intact under sustained use. At 60 grit, this roll delivers aggressive cut for initial material removal before finer finishing stages. It is sized at 3/8 inch diameter by 1 inch length with a 1/8 inch arbor hole, making it compatible with standard cartridge roll mandrels on die grinders and rotary tools. Machinists, fabricators, and industrial maintenance technicians are the primary users of this consumable abrasive format.
This cartridge roll is suited for use in industrial, manufacturing, and maintenance shop environments where controlled, localized grinding or blending is required. Common applications include weld blending, bore finishing, port grinding, and deburring of castings and machined parts. The small form factor allows access to contoured surfaces, inside diameters, and restricted areas where larger abrasives cannot reach. It is sold by the roll with a minimum order quantity of 100 rolls.
Designed for use with standard 1/8 inch shank cartridge roll mandrels mounted in die grinders, straight grinders, or rotary tools operating at appropriate RPM for this roll size.
Installation is performed by threading the cartridge roll onto a compatible mandrel until it is firmly seated. Ensure the die grinder or rotary tool is disconnected from power before loading or changing the roll. Always verify the tool RPM rating does not exceed the maximum rated speed for the abrasive. Wear appropriate PPE including eye protection and gloves during use and when changing abrasives.
