1" length x 1/2"Diameter Cartridge Roll are MADE IN USA with aluminum oxide grains, which is a great general-purpose abrasive for blending, deburring, and polishing high-tensile materials and ferrous alloys. Cartridge rolls are pieces of abrasive cloth rolled together tightly and glued together in either a straight or tapered shape. They are used on a mandrel, on high-speed tools, to sand/grind those tight, hard-to-reach areas that other coated abrasives can't hit.

The cartridge rolls are tightly spun abrasive tubes made with close coated, resin bonded, aluminum oxide. It is ideal for accessing small, hard-to-reach spaces. This cartridge roll is great for high-speed deburring and flash removal. They are used for grinding in hard-to-reach areas or on flat and contoured surfaces.
