Discs are made from emery paper attached to a stiff backing material. They are used in the benching phase. AII discs are round and flat, sizes range from 1/2″ to 3 inches in diameter. Small discs from 1/2″ to 1-1/2″ have an adhesive backing for mounting. Large discs 1″ to 3″ have a screw or snap for mounting. Discs are used with die grinders, right angle, and 45 degree angle heads. They are used to smooth large radii and to “sand” down deep cutter marks. Discs cut quickly so caution should be used.
