Merit Abrasives 08834180251 Cartridge Roll 3/8 in 80 Grit

Product Description

The MERIT ABRASIVES 08834180251 is a straight cartridge roll designed for precision deburring, blending, and finishing of metal surfaces. Built with aluminum oxide abrasive, this roll delivers consistent stock removal across a medium grit range. At 3/8 inch in diameter, it fits standard mandrel-mounted rotary tool setups used in die grinders and electric or pneumatic hand tools. Metal fabricators, machinists, and maintenance technicians rely on this type of roll for controlled material removal in bores, slots, and contoured surfaces where flat abrasives cannot reach. The 80 grit rating positions it as a medium-grade option suited for general-purpose blending without aggressive surface damage.

This cartridge roll is used in metalworking applications including weld blending, port matching, and surface preparation on ferrous and non-ferrous alloys. Typical install scenarios include machine shop finishing operations, HVAC component fabrication, and maintenance repair work where internal or hard-to-reach surfaces require abrasive finishing. The compact 3/8 inch diameter allows access into tight geometries that larger abrasive formats cannot address. Sold individually, with a minimum order quantity of 100 units, making it appropriate for shop-floor stocking or job lot procurement.

Compatibility

Designed as an OEM-style replacement consumable for use with standard mandrel-mounted cartridge roll holders compatible with 3/8 inch diameter straight cartridge rolls in die grinders and rotary finishing tools.

Installation Notes

Cartridge rolls are installed by a machinist or metalworker onto a threaded or tapered mandrel secured in a die grinder or rotary tool. 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 the mandrel or tool. Inspect the roll for tears or unraveling before use and replace immediately if the abrasive cloth shows signs of separation.
