3M 7010309059 Straight Cartridge Roll 120 Grit 1/2 in

Product Description

The 3M 7010309059 is a straight cartridge roll abrasive designed for deburring, blending, and finishing in tight contours, slots, and internal bores where flat abrasives cannot reach. Built on a cloth backing with aluminum oxide grain at 120 grit, this roll delivers consistent fine-grade cutting action throughout its working life. At 0.5 inches in diameter, it mounts on a mandrel and runs at up to 24,000 RPM on die grinders and rotary tools. Metalworkers, fabricators, and maintenance technicians use it for edge work, weld blending, and surface prep on steel and other hard metals.

This cartridge roll is suited for precision finishing applications in metal fabrication shops, aerospace maintenance, tool-and-die work, and general industrial grinding. The fine 120 grit is appropriate for final deburring passes, light stock removal, and surface conditioning where a smoother finish is required after coarser grinding steps. The cloth backing provides flexibility to conform to curved or irregular surfaces without tearing under rotary load.

Key Features

• 120 grit aluminum oxide abrasive for fine-grade material removal and finishing
• Cloth backing offers flexibility for contoured and internal surface work
• 0.5 inch diameter fits standard small-bore mandrels for die grinders
• Rated to 24,000 RPM for use with high-speed rotary tools
• Straight cartridge profile for consistent contact in slots, holes, and channels

Compatibility

Designed for use on standard cartridge roll mandrels accepting a 0.5 inch diameter straight cartridge roll. Verify mandrel shank size and RPM rating before mounting.

Installation Notes

Installation is performed by metalworking professionals using a compatible mandrel and die grinder or rotary tool. Power down and disconnect the tool from any air or electrical source before mounting or removing the cartridge roll. Confirm the tool RPM rating does not exceed the 24,000 RPM maximum rated for this roll. Wear appropriate eye protection and follow shop safety protocols during operation.
