3M 7100086101 Aluminum Oxide Cartridge Roll 80 Grit

Product Description

The 3M 7100086101 is an aluminum oxide cartridge roll designed for precision grinding and deburring in metalworking and finishing applications. Built on an X-weight cloth backing, it delivers durability under moderate-to-heavy pressure. The abrasive is resin bonded for improved heat resistance, which helps maintain cut rate and extends roll life during extended use. At 80 grit, this roll is suited for aggressive stock removal and surface blending on ferrous and non-ferrous metals. Measuring 0.5 inches wide by 1 inch long with a 0.125-inch bore, it fits standard cartridge roll mandrels used in die grinders and flexible shaft machines.

This cartridge roll is used in metal fabrication, welding cleanup, and precision finishing work where a mounted abrasive roll provides access to contoured surfaces, slots, and bores. It is a common choice for maintenance machinists, metal fabricators, and industrial technicians who need consistent abrasive performance in tight or curved areas. Sold per roll with a minimum order quantity of 100 rolls, making it appropriate for shop stock or production environments.
