Merit Abrasives 08834180081 Cartridge Roll 80 Grit

Product Description

The MERIT ABRASIVES 08834180081 is a straight cartridge roll designed for precision grinding, deburring, and finishing work on metal and other hard surfaces. Built with aluminum oxide abrasive media at 80 grit, this roll delivers a medium-grade cut that balances material removal with surface refinement. At 0.25 inches in diameter, it fits standard cartridge roll mandrels and is suited for use in die grinders, straight grinders, and rotary tools. Machinists, fabricators, and maintenance technicians reach for this roll when working in tight bores, slots, and contoured areas where flat abrasive sheets cannot reach.

This cartridge roll is commonly used in metal fabrication shops, maintenance and repair operations, and light industrial settings. Typical applications include cleaning up weld seams inside tubing, deburring drilled holes, blending tool marks in confined areas, and surface prep before coating or assembly. The 80 grit rating makes it a practical choice for general-purpose stock removal on steel, aluminum, and similar materials without leaving an excessively coarse finish.

Installation Notes

This cartridge roll is installed by a machinist, fabricator, or maintenance technician using a compatible mandrel secured in a die grinder or rotary tool. Before mounting, ensure the tool is fully powered down and disconnected from its air or electrical supply. Thread the roll onto the mandrel per the mandrel manufacturer's instructions and confirm it is seated firmly before operating. Always wear appropriate eye and face protection and confirm the tool's RPM rating is compatible with the abrasive roll before use.
