Merit Abrasives 08834180327 Cartridge Roll 80 Grit 1/2 in

Product Description

The MERIT ABRASIVES 08834180327 is a straight cartridge roll designed for precision deburring, blending, and surface finishing in tight contours, slots, and drilled bores. Built with aluminum oxide abrasive at 80 grit, this roll delivers medium-grade cutting action suited to ferrous metals, aluminum, and general shop materials. The 1/2-inch diameter profile fits standard mandrels and die grinders used by machinists, fabricators, and metalworking tradespeople. At 0.025 pounds per unit, it is lightweight and easy to handle during extended use. The 1/8-inch pilot hole diameter ensures secure mandrel mounting for consistent, concentric rotation during operation.

This cartridge roll is intended for use on die grinders, drill presses, and rotary tools in metal fabrication, welding shops, and general maintenance environments. The straight profile is well suited for accessing cylindrical bores, inside diameters, weld seams, and contoured surfaces where flat or disc abrasives cannot reach. The 80-grit aluminum oxide construction makes it appropriate for moderate stock removal and surface prep prior to finishing or coating operations.

Installation Notes

Cartridge rolls are installed by a machinist or metalworking technician onto a compatible mandrel fitted to a die grinder or rotary tool. Ensure the tool is fully powered down and unplugged before mounting or removing the roll. Inspect the mandrel for wear or runout before use, and do not exceed the maximum RPM rating of the abrasive roll as marked by the manufacturer. Eye protection and appropriate PPE are required during all grinding and finishing operations.
