3M 7100142738 Full Tapered Cartridge Roll 747D 60 Grit

Product Description

The 3M 7100142738 is a full tapered cartridge roll in the 747D series, designed for aggressive stock removal and precision grinding on metal and other hard surfaces. Built on an X-weight cloth backing with resin bonding for heat resistance, this roll measures 0.5 inches wide by 1.5 inches long with a 0.125-inch bore. The ceramic grain abrasive cuts fast and runs cooler than standard aluminum oxide thanks to an integrated grinding aid. Machinists, fabricators, and finishing technicians install these rolls in die grinders and mandrel-based rotary tools for contour grinding, deburring, and weld blending.

This cartridge roll is suited for use in tight-radius grinding applications where a tapered profile is required to access confined areas or follow curved workpiece geometry. The 60-grit X-weight construction targets medium-to-aggressive stock removal on ferrous metals, stainless steel, and hard alloys. It is commonly used in metalworking shops, maintenance and repair operations, and manufacturing environments where consistent cut rate and abrasive life are critical to throughput.

Key Features

• Ceramic grain abrasive for fast cut rate and extended abrasive life
• Integrated grinding aid reduces heat buildup during use
• Resin-bonded X-weight cloth backing resists tearing and deformation under load
• Full tapered profile allows access to contoured and recessed workpiece geometry
• 60 grit for medium-to-aggressive stock removal and weld blending
• Dimensions: 0.5 inches x 1.5 inches x 0.125 inches bore

Compatibility

Designed for use with standard mandrel-type die grinders and rotary tools that accept 0.125-inch bore cartridge rolls.

Installation Notes

These rolls are installed by a machinist or metalworking technician onto a compatible mandrel secured in a die grinder. Power down and disconnect the tool before mounting or removing the cartridge roll. Ensure the mandrel diameter matches the 0.125-inch bore before seating the roll, and confirm the tool RPM rating does not exceed the maximum rated speed of the abrasive. Eye protection and appropriate PPE are required during operation.
