Specialty abrasives and kits connect with compatible tools for sanding, buffing, polishing, or cleaning applications. Abrasive wheel adapters connect grinding or cut-off wheels to tools such as angle grinders or rotary tools. Spiral and cartridge rolls feature cloth backing covered in abrasive grain, and rolled in a tube or spiral shape to sand small parts and tight spaces. Expanding drums maintain the tightness of sanding belts while grinding. Abrasive mandrels connect abrasive stars and other products with compatible power tools. Bore polishers, abrasive stars, and sanding cross pads smooth out the insides and ends of tubes and pipes.
