3M 7010363544 Aluminum Oxide Cartridge Roll 80 Grit

Product Description

The 3M 7010363544 is an aluminum oxide cartridge roll designed for precision grinding, blending, and deburring on metal and other hard surfaces. Built on an X-weight cloth backing and resin bonded for heat resistance, this roll delivers consistent cut and durability under sustained use. It measures 0.375 inches in diameter by 1.5 inches in length with a 0.125-inch arbor, and runs at an 80-grit cut rate suited for moderate material removal and surface conditioning. Machinists, fabricators, and tool-and-die technicians reach for this format when working in bores, ports, and other confined geometries where flat abrasives cannot reach.

This cartridge roll is used in portable die grinders and bench-mounted spindle units across metal fabrication shops, maintenance facilities, and production grinding operations. Typical applications include bore finishing, weld blending inside tubing, port matching, and deburring cast or machined components. The compact 0.375-inch diameter allows access to tight internal radii and small-diameter holes where larger abrasive formats are impractical.

Key Features

• Aluminum oxide abrasive mineral for consistent cut on ferrous and non-ferrous metals
• X-weight cloth backing provides durability and resistance to tearing under load
• Resin bond construction enhances heat resistance during extended grinding passes
• 80-grit rating delivers moderate stock removal with controlled surface finish
• Compact 0.375-inch x 1.5-inch profile designed for access in bores and confined geometries

Compatibility

Designed for use with die grinders and spindle mandrels accepting a 0.125-inch arbor; confirm mandrel compatibility and maximum RPM rating before use.

Installation Notes

Installation is performed by fabricators, machinists, or maintenance technicians using a compatible mandrel mounted in a die grinder or rotary tool. Verify that the tool's rated RPM does not exceed the abrasive roll's maximum rated speed before operation. Wear appropriate eye protection and gloves when mounting or changing abrasive rolls. Inspect the roll for damage before each use and discard any roll that shows cracking, unraveling, or delamination of the cloth backing.
