Cartridge rolls consist of spiral-wound coated abrasive. The grit is embedded in a resin bond on a strong cloth backing material for maximum grinding effectiveness. The tool is held securely in place be a grooved conical arbour. Rolls are available in cylindrical or conical shapes and in different grit sizes. Cartridge rolls are ideal for deburring, fillet weld dressing, removal of flash on castings and working on hard to reach areas.
