3M 7010327695 Straight Cartridge Roll 320 Grit 3/8 in

Product Description

The 3M 7010327695 is a straight cartridge roll designed for precision deburring, blending, and finishing work in tight or contoured areas. It uses aluminum oxide abrasive on a cloth backing, rated at 320 grit for very fine material removal. At 3/8 inch in diameter, this roll is sized for use with a mandrel-mounted rotary tool or pneumatic die grinder. It is suitable for metalworking, fabrication, and finishing applications where consistent surface finish and controlled stock removal are required. Machinists, tool-and-die workers, and metal finishing technicians are the primary users of this consumable.

This cartridge roll is suited for deburring drilled and bored holes, blending weld seams, and finishing inside radii or recesses that flat abrasives cannot reach. The cloth backing provides conformability and durability under load. At 320 grit very fine grade, it is appropriate for final finishing passes rather than aggressive material removal. It performs on ferrous metals, non-ferrous alloys, and hard plastics in both job shop and production line environments.

Key Features

• Aluminum oxide abrasive for durable, consistent cut on metal surfaces
• 320 grit very fine grade suited for finish work and light deburring
• Cloth backing conforms to contours and withstands flex and tear
• 3/8 inch diameter fits standard cartridge roll mandrels for die grinders
• Rated to 24,000 RPM maximum for compatibility with high-speed rotary tools

Compatibility

Designed for use with mandrel-style holders accepting 3/8 inch diameter straight cartridge rolls, compatible with pneumatic die grinders and electric rotary tools running up to 24,000 RPM.

Installation Notes

Install the cartridge roll onto a correctly sized mandrel before mounting in the tool. Ensure the mandrel nut is tightened securely and the assembly is rated to at least the maximum RPM of the tool being used. Inspect the roll for damage before each use and discard any roll that shows fraying, core separation, or deformation. Always wear appropriate eye protection and ensure the workpiece is secured before operating.
