Merit Abrasives 08834180331 Cartridge Roll 180 Grit

Product Description

The MERIT ABRASIVES 08834180331 is an aluminum oxide straight cartridge roll designed for precision grinding, deburring, and surface finishing in tight spaces. Built with a 180-grit abrasive rated at very fine grade, this roll removes light stock and refines surfaces on metal, wood, and composites. The straight cartridge roll configuration provides consistent contact and uniform material removal throughout the roll's working life. With a maximum roll diameter of 0.5 inches and an overall length of 2 inches, it fits standard mandrels used by machinists, tool and die workers, and fabricators working in bores, slots, and contoured areas.

This cartridge roll is suited for use in die grinders and rotary tools across production and maintenance environments. Typical applications include deburring drilled holes, blending welds, and finishing interior contours in ferrous and non-ferrous metals. The 0.125-inch pilot hole diameter fits standard small-diameter mandrels common in metalworking shops, tool rooms, and fabrication facilities. It is sold individually but carries a minimum order quantity of 100 units, making it appropriate for production line procurement and shop replenishment.

Key Features

Installation Notes

Installation is performed by threading the cartridge roll onto a compatible mandrel and tightening to secure the roll without crushing the tube. Always confirm the mandrel RPM rating meets or exceeds the tool speed before use. Inspect the roll for tears or separation before mounting, and replace if any damage is present. Wear appropriate eye protection and follow shop safety protocols when operating rotary abrasive tools.
