Merit Abrasives 08834180312 Cartridge Roll 180 Grit 1/2 in

Product Description

The MERIT ABRASIVES 08834180312 is a straight cartridge roll designed for precision deburring, blending, and surface finishing in tight bores, slots, and contoured workpieces. Built with aluminum oxide abrasive, this roll delivers consistent stock removal at 180 grit, which falls in the very fine grade range. At 1/2 inch in diameter, it fits standard mandrels used in portable die grinders and drill presses. Metalworking professionals, tool-and-die shops, and fabrication technicians rely on this style of abrasive roll for controlled finishing passes where flat abrasive media cannot reach.

This cartridge roll is suited for use on ferrous and non-ferrous metals in both production and maintenance environments. Typical applications include finishing internal diameters, cleaning weld joints in confined areas, and blending parting lines on cast or machined components. It is used across general metalworking, aerospace fabrication, and industrial maintenance settings where a controlled, consistent scratch pattern is required at a very fine grit level.

Compatibility

Designed as a standard straight cartridge roll for use with compatible mandrels accepting a 1/2 inch diameter roll in die grinders, flexible shaft machines, and drill press setups.

Installation Notes

Straight cartridge rolls are installed by threading the roll onto the appropriate mandrel per the mandrel manufacturer's instructions. Ensure the spindle speed of the tool does not exceed the maximum rated RPM for the abrasive roll. Power down and disconnect the tool from its power source before mounting or removing the roll. Worn or frayed rolls should be replaced immediately and not re-used.
