3M 7010362437 Straight Cartridge Roll 320 Grit 1/4 in

Product Description

The 3M 7010362437 is a straight cartridge roll abrasive designed for precision deburring, blending, and finishing in tight bores, slots, and contoured surfaces. Built with aluminum oxide grain on a cloth backing, it delivers consistent stock removal at very fine (320 grit) cut rates. The 0.25-inch diameter profile fits standard mandrel-mounted die grinder setups used by machinists, fabricators, and finishing professionals. Rated to 24,000 RPM, it is suited for high-speed pneumatic and electric rotary tools where controlled surface refinement is required without aggressive material removal.

This cartridge roll is used in metalworking and fabrication applications where interior surface finishing is needed — such as inside tubing, castings, weld joints, and machined bores. The cloth backing provides flexibility to conform to slight contour variations, making it useful for both ferrous and non-ferrous metal finishing. It is also applied in surface prep work before coating or plating operations where a consistent, fine surface profile is required.

Compatibility

Designed for use with standard cartridge roll mandrels in die grinders and rotary tools that accept 0.25-inch diameter cartridge rolls running up to 24,000 RPM.

Installation Notes

A licensed machinist or finishing technician should mount the cartridge roll onto a correctly sized mandrel before use. Confirm the tool RPM rating does not exceed the 24,000 RPM maximum before operating. Wear appropriate eye and hand protection per ANSI abrasive product safety guidelines. Inspect the roll and mandrel for wear or damage before each use and replace if the abrasive shows uneven wear or the backing is compromised.
