Merit Abrasives 08834180100 Cartridge Roll 80 Grit 1/4 in

Product Description

The MERIT ABRASIVES 08834180100 is a straight cartridge roll designed for precision deburring, blending, and surface finishing in tight or contoured areas. Built with aluminum oxide abrasive at 80 grit, this roll delivers medium-grade cutting action suited for moderate material removal on steel, aluminum, and similar metals. The 1/4 inch diameter profile fits standard mandrels used in die grinders and rotary tools, making it a go-to for machinists, fabricators, and maintenance technicians working in bores, slots, and irregular internal surfaces.

This cartridge roll is used across metalworking and fabrication environments where conventional grinding wheels or sanding discs cannot reach. Typical applications include finishing weld joints inside tubing, deburring drilled holes, and blending internal radii on machined parts. The straight profile maintains consistent abrasive contact along the length of the roll, which is critical for uniform surface finish in repetitive operations. Sold as a single unit with a minimum order quantity of 100 pieces per order.

Compatibility

Designed as an OEM-style replacement and standard consumable for use with 1/4 inch diameter straight cartridge roll mandrels on die grinders and rotary tools common in metalworking and fabrication shops.

Installation Notes

Cartridge rolls are installed by threading the roll onto a compatible mandrel, which is then secured in the collet of a die grinder or similar rotary tool. Verify mandrel diameter matches the roll bore before mounting and ensure the tool is powered off and isolated before changing abrasives. Do not exceed the maximum RPM rating of the mandrel or tool. Eye protection and appropriate PPE should be worn during operation per standard shop safety practices.
