First choice for the parting of bars, hard materials and tough applications. A positive rake, single cavity (except 7 & 12 mm with double cavity), negative land and shoulders, provides extra cutting-edge strength. Medium-to-high feeds. A tough submicron grain size substrate with a PVD coating, recommended for general use for diverse operations on materials such as steels, alloy steels, austenitic stainless steel and high temperature alloys at a wide range of cutting speeds. Features high wear resistance and chipping durability.
