Dapra Corporation has just announced the availability of optional PCD tips for both their Backdraft (back draft) inserts and XPET inserts. These diamond-tipped inserts afford unsurpassed tool life for most aluminum and graphite milling applications. Their expected life is approximately 100 times that of normal TiAlN-coated inserts, providing the capability for high speeds and outstanding surface finishes.
Dapra's PCD-Tipped Backdraft inserts, for mold and die applications, are available in 1/2" and 3/4" diameters, with both 1/32" and 1/16" corner radii and a usable leg length of approximately 1/8".
Designed to be used with 90-degree Square Shoulder Mills, the XPET inserts are 16mm in length, with a 1/32" corner radius. The XPET inserts also offer a 1/8" usable leg length.
