3M 7010294691 Straight Cartridge Roll 40 Grit 3/8 in

Product Description

The 3M 7010294691 is a straight cartridge roll designed for precision grinding, deburring, and surface blending in tight-contour and internal-diameter applications. Built with an aluminum oxide abrasive bonded to a cloth backing, this roll delivers consistent stock removal at coarse 40 grit. It is rated for a maximum spindle speed of 24000 RPM and fits a 3/8 inch diameter mandrel. Machinists, metal fabricators, and maintenance trades use these rolls on die grinders and rotary tools to finish bores, slots, and curved surfaces where flat abrasives cannot reach.

This cartridge roll is suited for ferrous and non-ferrous metal grinding tasks in manufacturing, fabrication shops, and maintenance environments. The coarse 40 grit rating makes it effective for aggressive material removal, weld blending, and cleaning up casting flash. The cloth backing provides flexibility, allowing the roll to conform to irregular or curved workpiece profiles without tearing under load. It is sold individually and available in multiples of 100 units for shop-stock replenishment.

Compatibility

Installation Notes

Cartridge rolls are installed by a machinist or metal fabricator using a compatible threaded mandrel chucked into a die grinder or rotary tool. Before mounting, confirm the tool spindle speed does not exceed the 24000 RPM rating of this roll. Inspect the roll for damage before each use and do not use on a tool that exceeds the rated speed. Always wear appropriate eye protection and follow shop safety procedures when operating rotary abrasives.
