Merit Abrasives 08834180489 Cartridge Roll 60 Grit 3/4 Inch

Product Description

The MERIT ABRASIVES 08834180489 is a straight cartridge roll designed for precision deburring, blending, and surface finishing in tight areas and contoured workpieces. Built with aluminum oxide abrasive at 60 grit, this roll delivers consistent medium-grade cutting action suited for ferrous and non-ferrous metals. The straight cartridge profile allows it to seat into a mandrel-driven rotary tool or die grinder for controlled stock removal. Machinists, fabricators, and tool-and-die technicians rely on this style of abrasive roll for internal bore work, slot finishing, and weld seam cleanup where flat abrasive media cannot reach.

This cartridge roll is used in metalworking, manufacturing, and maintenance-repair-overhaul environments. Typical applications include finishing the interior surfaces of drilled or bored holes, smoothing weld joints in recessed areas, and blending parting lines on cast or forged parts. The 60-grit aluminum oxide construction makes it well suited for initial material removal before stepping to finer grits. It is sold as a single unit per package with a minimum order quantity of 100 pieces, making it appropriate for production-line and shop consumable procurement.

Key Features

Compatibility

Designed for use with standard straight cartridge roll mandrels in die grinders, flexible shaft machines, and bench-mounted rotary tools configured for cartridge roll abrasives.

Installation Notes

Installation is performed by trade professionals and machinists familiar with rotary abrasive tooling. Ensure the die grinder or rotary tool is powered off and unplugged before mounting the cartridge roll onto the mandrel. Verify the mandrel size matches the roll arbor bore, and confirm the tool RPM rating does not exceed the abrasive roll maximum operating speed. Eye protection and appropriate PPE are required during all grinding and finishing operations.
