3M 7100136781 Cartridge Roll 80 Grit 0.5x1.5x0.125 in X-weight

Product Description

The 3M 7100136781 is a ceramic grain abrasive cartridge roll engineered for aggressive material removal on metal and hard surfaces. Built on an X-weight cloth backing, it delivers the durability and flexibility needed for tight-radius and contoured grinding applications. The resin bond construction provides heat resistance during extended use, and the integrated grinding aid promotes cooler cutting to extend abrasive life and reduce discoloration on workpieces. At 80 grit, this roll sits in the medium-coarse range, making it well suited for blending welds, deburring edges, and removing scale or rust in preparation for finishing.

This cartridge roll is designed for use with mandrel-driven rotary tools and die grinders in fabrication shops, maintenance facilities, and field service environments. The 0.5-inch width and 1.5-inch length with a 0.125-inch arbor hole make it appropriate for inside-diameter work, port grinding, and other tight-access areas where larger abrasives cannot reach. Metalworking professionals, tool and die technicians, and maintenance mechanics are the primary installers.

Key Features

• Ceramic abrasive grain for fast cut rate and long service life
• X-weight cloth backing for strength and flexibility in contoured applications
• Resin bond construction resists heat buildup during continuous grinding
• Grinding aid promotes cooler cutting and reduces workpiece heat discoloration
• 80 grit medium-coarse grade suited for weld blending, deburring, and scale removal

Compatibility

Designed for use with standard abrasive cartridge roll mandrels sized to accept a 0.125-inch arbor, compatible with common die grinders and rotary tools used in metalworking and fabrication applications.

Installation Notes

Installation is performed by threading the cartridge roll onto a compatible mandrel and tightening to the mandrel manufacturer's specification. Ensure the die grinder or rotary tool is disconnected from power before mounting or removing the roll. Always verify that the tool's rated RPM does not exceed the maximum RPM rating of the abrasive. Eye protection and appropriate PPE are required during operation.
