3M 7010291242 Straight Cartridge Roll 150 Grit 1/4 in

Product Description

The 3M 7010291242 is a straight cartridge roll abrasive designed for precision material removal and surface finishing in tight spaces and contoured areas. Built with an aluminum oxide abrasive on a cloth backing, this roll operates at up to 24,000 RPM and delivers a very fine 150-grit finish. At 0.25 inches in diameter, it fits standard mandrel-style die grinders and rotary tools used in metalworking, weld blending, and deburring applications. Machinists, fabricators, and maintenance technicians are the primary installers and users of this consumable abrasive product.

This cartridge roll is suited for use in die grinders and other rotary tools where a small-diameter abrasive roll is needed for interior bore finishing, port blending, weld seam cleanup, and fine surface preparation on metal workpieces. The cloth backing provides flexibility to conform to curved and irregular surfaces, making it effective in applications where flat abrasive sheets cannot reach. It is commonly used in metal fabrication shops, maintenance and repair operations, and precision manufacturing environments.

Installation Notes

Installation is performed by threading the cartridge roll onto a compatible mandrel and securing it per the mandrel manufacturer's instructions before mounting in the rotary tool. Always confirm the tool's operating RPM does not exceed the 24,000 RPM rating of this roll before use. Wear appropriate eye protection and follow applicable shop safety procedures when operating rotary abrasive tools. Inspect the roll for damage or deterioration before each use and discard if the abrasive shows signs of uneven wear or separation from the backing.
