Abstract:
A tool bit with a surface layer metallurgically bonded on a substrate layer using electrospark deposition (ESD) that allows the tool bit to reduce camout and engage a fastener head for one-handed starting and removal. The surface layer has a rougher finish, compared to conventional tool bits, and therefore better grips engagement surfaces of a mating recess of the fastener during use. The reduction of camout provides greater durability to the tool bit and resists erosion and wear of the engagement surfaces of the fastener.
