Sandvik Coromant CoroMill 425 suits automotive castings

CoroMill 425 is an eight-edge finishing tool designed for the face-milling of automotive castings. The tool is said to greatly improve metal removal rate and tool life in the ISO K application area.

Typical cast components include engine and cylinder blocks, axle housings, brake carriers and crankcases made of GCI, NCI and CGI materials. Due to its patented setting system, the tool is said to feature precise and reliable insert positioning that makes set-up simple.

On the CoroMill 425, the same inserts can be used as working or wiper inserts. Wiper inserts are mounted in cassettes on the face of the tool. In addition, the insert version with a 25° entry angle and optimised chamfer is designed to reduce break-outs and burr formation on the workpiece. A choice of wear-resistant GC1010 PVD insert grade for dry milling or K20W grade for wet milling enables extended tool life.
