3M 7010327469 Straight Cartridge Roll 40 Grit 1/2 in

Product Description

The 3M 7010327469 is a straight cartridge roll abrasive designed for use with mandrel-mounted rotary tools and die grinders. Built on a cloth backing with aluminum oxide grain at 40 grit, it delivers aggressive material removal in a compact 0.5-inch diameter format. The coarse grade makes it well suited for deburring, blending welds, and shaping metal or composite surfaces in tight internal contours where flat sheets or discs cannot reach. Maximum operating speed is 24,000 RPM. Machinists, fabricators, and maintenance technicians are the typical end users.

Straight cartridge rolls of this type are used in production and job-shop metal fabrication environments as well as maintenance and repair operations. They excel in cylindrical bores, die cavities, pipe ends, and other confined geometries where a straight profile is needed. The 0.5-inch diameter suits narrow slots and small-radius contours. The cloth backing provides flexibility and resistance to tearing under moderate to aggressive feed pressure.

Key Features

• Aluminum oxide abrasive grain for consistent cut rate on ferrous and non-ferrous metals
• 40 grit coarse grade for rapid stock removal and weld blending
• Cloth backing resists tearing and conforms to contoured surfaces
• 0.5-inch diameter fits standard mandrel setups for die grinders and flex shafts
• Rated to 24,000 RPM for use with high-speed rotary tools

Compatibility

Designed as a standard straight cartridge roll for use with compatible mandrels on die grinders, air tools, and electric rotary tools rated to accommodate 0.5-inch diameter cartridge rolls at up to 24,000 RPM.

Installation Notes

A licensed machinist or trained fabricator should mount the cartridge roll onto the correct mandrel size before use. Always confirm the tool spindle speed does not exceed the 24,000 RPM maximum rating before operation. Inspect the roll for damage before mounting, and never force the roll onto a mandrel that does not match its bore. Eye protection and appropriate PPE are required during use.
