Resin Bond (RB) diamond is recommended for phenolic, polyimide and vitrified bond systems. It's unique fracturing characteristic produces a free cutting action that provides optimal performance when machining nonferrous materials such as tungsten carbide, glass and a variety of ceramics. Resin bond diamond clad with a metallic coating such as Nickel or Copper may provide additional tool life, as the metal coating improves heat dissipation and the improved surface texture enhances particle retention in the bond.
