Overlap and Slotted Discs are manufactured from individual layers of coated abrasive material with a threaded arbor hole. These discs are designed to allow the disc to compress when entering the inside diameter of a part allowing full contact between the disc and part thus producing a uniform finish. Overlap and Slotted discs are recommended for precise finishing applications on internal diameters for all metals.
They are available in Aluminum Oxide grain with Resin Bond.
