3M 7100085775 Tapered Cartridge Roll 80 Grit 3/8x1x1/8 in

Product Description

The 3M 7100085775 is a full tapered cartridge roll engineered for precision grinding and finishing in tight or contoured areas. Built on a durable X-weight cloth backing with aluminum oxide abrasive grain and a resin bond system, this roll delivers consistent cut and heat resistance through extended use cycles. At 80 grit, it handles moderate stock removal and surface blending on metal and similar hard materials. The tapered profile allows the roll to reach into grooves, slots, and internal diameters that flat or straight rolls cannot access. Tradespeople and machinists reach for this format when inside-diameter work or contour finishing demands a compact, controllable abrasive tool.

This cartridge roll is suited for use with mandrel-mounted rotary tools, die grinders, and similar power tools in fabrication shops, maintenance environments, and light manufacturing settings. The 3/8-inch diameter and 1-inch length make it appropriate for small-bore and detail finishing tasks. The X-weight cloth backing resists tearing under side-load pressure, making it reliable for aggressive contact grinding as well as lighter blending passes.

Key Features

• Aluminum oxide grain provides consistent cut on ferrous and non-ferrous metals
• X-weight cloth backing resists tearing and flexing under load
• Resin bond construction improves heat resistance during extended grinding cycles
• Full tapered profile accesses grooves, slots, and internal contours
• 80 grit rating suited for moderate stock removal and surface blending

Compatibility

Designed for use with standard mandrel-mounted rotary tools and die grinders that accept 1/8-inch shank mandrels and cartridge roll accessories.

Installation Notes

Installation is performed by threading the cartridge roll onto a compatible mandrel shank and tightening per the mandrel manufacturer's guidance. Ensure the rotary tool is powered off and unplugged before mounting or removing the roll. Do not exceed the maximum RPM rating of the mandrel or tool. Inspect the roll for damage before each use and replace if the backing shows tearing or the abrasive surface is fully worn.
