3M 7100086093 Aluminum Oxide Cartridge Roll 80 Grit

Product Description

The 3M 7100086093 is an aluminum oxide cartridge roll designed for precision grinding, deburring, and surface blending in tight bore and contoured areas. Built on an X-weight cloth backing with resin bonding, this roll handles heat generated during aggressive stock removal without breakdown. The abrasive measures 0.375 inches in diameter by 1 inch in length with a 0.125-inch arbor hole, making it sized for use on mandrel-mounted rotary tools and die grinders. At 80 grit, it delivers medium-cut performance suited to weld cleanup, port work, and ID finishing on metal components.

This cartridge roll is used by machinists, fabricators, maintenance technicians, and tool-and-die professionals working on internal diameter surfaces, curved profiles, and restricted-access areas where flat abrasive media cannot reach. Typical applications include deburring drilled holes, blending weld beads in tubing, and finish-grinding small bores on ferrous and non-ferrous metals. The roll format allows consistent abrasive contact as the roll wears, extending usable life compared to flap or drum styles.

Compatibility

Designed for use with standard 0.125-inch shank mandrels on die grinders and rotary tools commonly used for bore finishing and contour grinding applications.

Installation Notes

Always power down and lock out the rotary tool or die grinder before mounting or removing the cartridge roll on the mandrel. Ensure the mandrel shank and arbor hole are clean and free of debris before installation. Do not exceed the maximum RPM rating of the mandrel or the tool. Operators should wear appropriate eye protection and gloves during use.
