3M 7010327680 Straight Cartridge Roll 80 Grit 5/16 in

Product Description

The 3M 7010327680 is a straight cartridge roll abrasive designed for precision grinding, deburring, and finishing in tight contours, slots, and bores. Built on a cloth backing with aluminum oxide abrasive grain, this roll delivers consistent stock removal at 80 grit, a medium grade suited for moderate material removal and surface blending. It mounts on a cartridge roll mandrel and spins at up to 24,000 RPM. Machinists, tool-and-die workers, and metal fabricators use this type of roll for finish work on ferrous and non-ferrous metals where larger abrasive tooling cannot reach.

This cartridge roll is sized at 5/16 inch in diameter, making it well suited for internal grinding and deburring of small-diameter holes, slots, and recessed surfaces. Typical applications include weld blending, port work, and edge finishing on metal parts in fabrication, manufacturing, and maintenance settings. The cloth backing provides flexibility and durability under rotary load, allowing the roll to conform slightly to the workpiece surface for more even contact.

Key Features

• Aluminum oxide abrasive grain for effective stock removal on metals
• 80 grit medium grade balances cut rate and surface finish
• Cloth backing adds durability and slight flexibility for contour work
• 5/16 inch diameter fits small bores, slots, and confined areas
• Rated up to 24,000 RPM for use with die grinders and rotary tools

Compatibility

Designed for use with standard cartridge roll mandrels on die grinders and rotary tools rated to the appropriate RPM. Verify mandrel size matches the roll arbor before mounting.

Installation Notes

Install cartridge rolls onto the correct mandrel size and tighten securely before operation. Always confirm the tool RPM rating does not exceed the 24,000 RPM maximum of this roll. Wear appropriate eye and face protection during grinding operations. Inspect the roll for damage or wear before each use and replace if the abrasive material is worn through to the backing core.
