Dormer Pramet now offers the Pramet SF and SM geometries for machining of high temperature alloys and stainless steel. 

The SF geometry features a sharp positive geometry with inclination cutting edge of 14.5 degrees and is suitable for finishing applications in continuous cut with very low cutting forces. The SM chipbreaker is a wear-resistant, universal geometry for medium machining (finishing up to roughing) suitable for continuous and interrupted cut.

Both new chipbreakers are suitable for materials with poor machinability such as stainless steels, mild steels and high temperature alloys. The SF and other geometries are available in a variety of grades and have been designed to promote low cutting forces and prevent work-hardening, reducing the risk of vibration when turning thin-walled components.
