3M 7100141481 Full Tapered Cartridge Roll 80 Grit

Product Description

The 3M 7100141481 is a full tapered cartridge roll designed for precision grinding and deburring on metal surfaces. Built on an X-weight cloth backing with resin bonding, it handles the heat generated during aggressive material removal. The ceramic grain cuts consistently under load and is assisted by a built-in grinding aid that keeps surface temperatures lower during use. At 0.5 inches wide, 1.5 inches long, and 0.125 inches in bore diameter, this roll mounts on standard cartridge roll mandrels used in die grinders and burr machines. Licensed tradespeople and shop machinists reach for this roll when working inside bores, on weld seams, or along contoured edges that flat media cannot reach.

This cartridge roll is suited for ferrous and non-ferrous metalworking applications in both production shop and field environments. Typical uses include weld blending, edge chamfering, port work, and surface conditioning in tight or contoured areas. The tapered profile allows the roll to conform to curved or irregular profiles without bridging. It is commonly used by pipefitters, welders, machinists, and fabricators working on tubing, pipe ends, castings, and machined components.

Key Features

• Ceramic grain construction for consistent, aggressive stock removal
• X-weight cloth backing provides durability under high-pressure grinding
• Resin bond formulation resists heat buildup during extended use
• Built-in grinding aid promotes cooler cutting and longer roll life
• Full tapered profile conforms to curved and contoured workpiece surfaces
• 80 grit provides a balance of cut rate and surface finish for blending and deburring

Compatibility

Designed for use with standard cartridge roll mandrels on die grinders, pencil grinders, and burr machines. Verify mandrel diameter matches the 0.125 inch bore before mounting.

Installation Notes

Cartridge rolls are installed and removed by a qualified operator using the correct mandrel size for the bore diameter. Ensure the grinder is fully powered down and disconnected before changing rolls. Do not exceed the maximum RPM rating of the roll or the tool. Inspect the roll for damage before each use and discard any roll showing signs of delamination or core separation.
