3M 7100085777 Full Tapered Cartridge Roll 60 Grit

Product Description

The 3M 7100085777 is a full tapered cartridge roll designed for precision grinding, deburring, and surface blending on metal and other hard materials. Built on a durable X-weight cloth backing, this roll uses aluminum oxide abrasive grain resin-bonded to the substrate for consistent cut and heat resistance during demanding applications. At 60 grit, it delivers aggressive material removal while maintaining enough control for contour work and tight radii. The tapered profile seats securely on a mandrel, making it a standard choice for die grinders and rotary tools used in fabrication and finishing operations.

This cartridge roll is suited for metalworking applications including weld blending, edge deburring, bore finishing, and surface preparation on ferrous and non-ferrous metals. The tapered full-taper geometry allows it to reach into slots, ports, and contoured surfaces where flat abrasives cannot. It is commonly used in fabrication shops, maintenance and repair operations, and production grinding environments by machinists, tool and die workers, and metal finishing technicians.

Key Features

• Full tapered cartridge roll design seats on standard mandrel for secure, concentric rotation
• Aluminum oxide grain provides aggressive, consistent stock removal on metal
• X-weight cloth backing resists tearing and flexing under load
• Resin bond construction offers heat resistance for extended service life
• 60 grit classification for medium-aggressive material removal and contour work
• Compact 3/8 x 1-1/2 x 1/8 inch dimensions suit die grinders and rotary tool applications

Compatibility

Designed as an OEM-style replacement cartridge roll for use with standard mandrel-driven rotary tools and die grinders accepting 1/8 inch shank mandrels.

Installation Notes

Installation is performed by metalworking or maintenance technicians using a compatible mandrel sized to the 1/8 inch bore of the cartridge roll. Ensure the mandrel nut is properly tightened and the roll is fully seated before operating the tool. Confirm the tool RPM rating meets or exceeds the abrasive roll rating before use. Always wear appropriate eye protection and follow shop safety protocols when operating rotary abrasive tooling.
