Skinners are high quality wire wheels especially encapsulated in a durable bonding material that holds the wire bristles stiff and straight. The bristles will not bend, flare, or splinter. Removes paint, caulking, rust and sealers without loading up and will reach areas where grinding discs can not. They are excellent for deep indentations, sharp contours and flanged lips. They can run at speeds from 15,000 to 20,000 rpm, and will outlast most wire brushes on the market 40 to 1. Because of its concave shape the flared skinner permits even better service by enabling the user to cut close to squared corners without interference from its drive arbor bolt head.
