The stringy "bird's nest" that forms around tools and work pieces when chips fail to break causes shortened tool life, broken tools, poor finishes, and costly machine downtime. To combat this problem, Mastertech Diamond Products offers customized laser-etched 3-D chip breaker geometries cut into its polycrystalline-diamond and chemical-vapor-deposited-diamond inserts and cutting tools. Since laser etching produces a smoother surface than ground edges, buildup when machining soft materials is minimized. Laser-etched 3-D chip breaker inserts can last up to three times longer than conventional diamond tooling. Each chip breaker meets the cutting requirements of the application. Inserts are provided for both roughing and finishing operations in all ANSI and ISO styles including square, triangle, and round, as well as in 35°, 55°, and 80° geometries.
