Merit Abrasives 08834180085 Cartridge Roll 1/4 in 180 Grit

Product Description

The MERIT ABRASIVES 08834180085 is a straight cartridge roll designed for precision deburring, blending, and surface finishing in tight spaces and contoured areas. Built with aluminum oxide abrasive, this roll delivers consistent cut and finish on ferrous metals, hardened steel, and other hard materials. At 1/4 inch in diameter and rated at 180 grit, it falls in the very fine grade range, making it well-suited for finishing passes where scratch pattern control matters. Metalworkers, tool and die technicians, and fabricators typically use this type of cartridge roll mounted on a mandrel in a die grinder or rotary tool for controlled stock removal in hard-to-reach geometry.

This cartridge roll is used in industrial and job-shop metalworking environments where access to bores, slots, and contoured surfaces requires a small-diameter abrasive. It is appropriate for manual and semi-automated finishing operations on precision components, weld cleanup in confined areas, and port work. The very fine 180-grit specification makes it a finishing tool rather than a heavy material-removal abrasive. Sold individually, this roll is typically ordered in quantities of 100 units to maintain workflow without frequent restocking interruptions.

Compatibility

Designed for use with standard 1/4 inch straight cartridge roll mandrels compatible with die grinders and rotary finishing tools used in metalworking applications.

Installation Notes

Straight cartridge rolls are installed by a metalworking technician onto a compatible mandrel following the mandrel manufacturer's seating instructions. Ensure the mandrel and roll are rated for the RPM of the tool being used before operation. Inspect the roll for damage before each use and do not force the roll onto an oversized mandrel. Always wear appropriate eye and face protection when operating abrasive tooling.
