3M 7100102013 Cartridge Roll 180 Grit 3/4 Inch Aluminum Oxide

Product Description

The 3M 7100102013 is a straight cartridge roll abrasive designed for use with mandrel-mounted rotary tools and die grinders. It uses an aluminum oxide abrasive grain bonded to a cloth backing, rated at 180 grit for very fine material removal and surface finishing. At 3/4 inch in diameter, this roll fits standard cartridge roll mandrels and is suited for controlled finishing work in tight areas, contoured surfaces, and ID grinding applications. It is rated to a maximum of 16,000 RPM, making it compatible with high-speed pneumatic and electric die grinders commonly used in metalworking, fabrication, and maintenance trades.

This cartridge roll is used in light deburring, blending, and finishing operations on metal, including weld cleanup, port finishing, and surface preparation before coating or inspection. The very fine 180 grit designation makes it appropriate for final-pass finishing rather than aggressive stock removal. Typical users include machinists, fabricators, maintenance technicians, and industrial tradespeople who require consistent scratch patterns and dimensional control in confined workspaces.

Key Features

• Aluminum oxide abrasive grain for consistent cut on ferrous and non-ferrous metals
• 180 grit very fine grade suited for finish passes and surface blending
• Cloth backing provides flexibility for contoured and curved surface work
• 3/4 inch diameter fits standard cartridge roll mandrels
• Rated to 16,000 RPM for use with high-speed die grinders
• Straight roll profile for uniform contact in cylindrical and ID applications

Compatibility

Designed for use with standard cartridge roll mandrels in pneumatic and electric die grinders that accept 3/4 inch diameter straight cartridge rolls and operate within the 16,000 RPM maximum speed rating.

Installation Notes

Installation is performed by a machinist or fabricator using a compatible mandrel sized for 3/4 inch cartridge rolls. Ensure the die grinder is fully powered off and depressurized before mounting or removing the roll. Do not exceed the 16,000 RPM maximum speed rating. Inspect the roll for damage before each use and confirm the mandrel nut is secure before operating.
