Merit Abrasives OLD08834180310 Cartridge Roll 120 Grit

Product Description

The MERIT ABRASIVES OLD08834180310 is a straight cartridge roll designed for precision grinding and finishing in tight or contoured areas. Built with aluminum oxide abrasive at 120 grit, this roll delivers a fine cut suited for deburring, blending, and light stock removal on metal, wood, and composite surfaces. The 0.5-inch diameter profile fits standard mandrel-mounted rotary tools and die grinders. Fabricators, machinists, and finishing technicians use this roll where flat abrasives cannot reach, particularly inside bores, slots, and curved surfaces.

This cartridge roll is commonly used in metalworking shops, fabrication facilities, and maintenance environments requiring controlled surface finishing. The straight profile makes it well suited for cylindrical bores and straight-walled channels. It is compatible with mandrel-driven pneumatic or electric die grinders and rotary tools. At 120 grit aluminum oxide, it works effectively on ferrous metals, non-ferrous metals, and hardwoods where a fine finish is needed without aggressive material removal.

Installation Notes

Cartridge rolls are installed by threading the roll onto a compatible abrasive mandrel and tightening according to the mandrel manufacturer's instructions. Ensure the tool is powered off and disconnected from the air supply or electrical source before mounting or removing the roll. Do not exceed the maximum RPM rating of either the roll or the mandrel. Eye protection and appropriate PPE should be worn during operation, as required by applicable workplace safety standards.
