Part of Dormer Pramet’s second product launch of 2015, the SF geometry features a sharp, positive rake of 14.5°. It is suitable for finishing applications in continuous cut with very low forces.
The SM geometry has a positive rake of 13° and is said to be a wear-resistant, universal geometry for medium machining (finishing up to roughing) and is suitable for continuous and interrupted cuts.
Both geometries are available in a variety of grades and have been designed to promote low cutting forces and prevent work-hardening. This helps to reduce the risk of vibration when turning thin-walled components.
