Dapra Corporation now offers optional PCD tips for its Backdraft and XPET inserts. Useful for mold and die operations, the company’s PCD-tipped Backdraft inserts are available in diameters of 1/2" and 3/4", with 1/32" and 1/16" corner radii and a usable leg length of approximately 1/8". The XPET inserts are designed for use with 90-degree square shoulder mills. They measure 16 mm in length, with a corner radius of 1/32" and usable leg length of 1/8".
These diamond-tipped inserts have been designed to extend tooling life when used in aluminum and graphite milling applications. According to the company, this alternative to TiAlN-coated inserts provides favorable surface finishes.
