3M 7010364003 Straight Cartridge Roll 320 Grit 5/8 in

Product Description

The 3M 7010364003 is a straight cartridge roll designed for precision surface finishing and deburring on metals, composites, and similar materials. Built with aluminum oxide abrasive bonded to a cloth backing, it delivers consistent stock removal and surface blending in tight bores, slots, and contoured areas. Rated at 320 grit, this roll falls in the very fine grade range, making it well-suited for final finishing passes where a smooth, uniform surface is required. The cloth backing provides flexibility and durability through repeated use. This cartridge roll is installed on a mandrel and used with rotary power tools or die grinders by machinists, tool and die makers, and maintenance technicians.

This cartridge roll is used in applications requiring fine finishing inside bores, holes, and recesses where flat abrasives cannot reach. Typical scenarios include deburring drilled holes, blending weld seams in confined areas, and surface conditioning prior to inspection or coating. It is suited for use in metal fabrication shops, maintenance and repair operations, and production environments handling ferrous and non-ferrous metals. The 5/8 inch diameter profile fits standard cartridge roll mandrels used in die grinders and flexible shaft machines.

Key Features

• 320 grit aluminum oxide abrasive for very fine surface finishing
• Cloth backing provides flexibility and resistance to tearing during use

Compatibility

Designed for use with standard cartridge roll mandrels compatible with 5/8 inch diameter straight cartridge rolls. Verify mandrel size and arbor compatibility before installation.

Installation Notes

Installation is performed by machinists or maintenance technicians using a compatible mandrel in a die grinder or rotary tool. Ensure the tool is powered off and disconnected from its air or electrical supply before loading or removing the cartridge roll. Do not exceed the rated maximum speed of 16,000 RPM. Inspect the roll for damage or wear before each use and replace if the abrasive layer shows separation from the backing.
