3M 7100080024 Straight Cartridge Roll 180 Grit 1/4 in

Product Description

The 3M 7100080024 is a straight cartridge roll designed for precision grinding, blending, and finishing on metal and other hard surfaces. Built with an aluminum oxide abrasive bonded to a cloth backing, it delivers consistent material removal at a Very Fine 180 grit rating. The straight profile fits standard mandrel-driven rotary tools and die grinders, making it a reliable choice for deburring, surface prep, and contour finishing in tight areas. At a maximum speed of 24,000 RPM, it handles both light stock removal and finish work without loading quickly.

This cartridge roll is suited for use in fabrication shops, maintenance facilities, and light industrial environments where controlled, fine finishing is required. Typical applications include weld blending, edge radiusing, port work, and surface conditioning on ferrous and non-ferrous metals. The 0.25-inch diameter fits narrow grooves, bores, and contoured workpieces where larger abrasives cannot reach. It is installed by a machinist, metalworker, or maintenance technician using a compatible mandrel and rotary power tool.
