Suitable for high feed rates at low cutting depths. Light to medium machining of stainless steels. Also for difficult to machine materials. Sharp cutting edges for a soft cutting action. Finish machining of difficult to machine materials such as Inconel or titanium. Medium machining of general and alloy steel grades together with light machining of cast iron, Positive primary chamfer for a for smooth cutting. Distinctive chip clearance geometry coupled with moderately positive cutting angle give the best chip clearance. Main application is stainless steel. First choice for medium machining of cast iron. High cutting edge stability due to flat primary chamfer. For finishing to medium roughing of aluminium. Extremely positive chip-breaker geometry. Light and medium machining of titanium materials. Positive cutting angle and large chip breaking hollow permit focus on chip clearance. Chip breakers for medium machining. For general use over a wide range of materials. Copy turning in steel and stainless steel. Exceptionally positive chip breaker for reduced cutting forces. Suitable for copy turning. Machining of carbon steel and alloy steel. Only for KNUX inserts. Roughing operations on general, alloy and stainless steels. Large chip gullet combined with a wide flat primary chamfer for high feed rates. Also suitable for interrupted machining. Heavy machining of low-tensile and stainless steel. The positive primary chamfer and curved cutting edge reduce the cutting resistance. CBN For continuous cutting at low cutting depths under stable machining conditions. First choice for general machining. Suitable for continuous machining to slightly interrupted cutting, Special geometry for difficult machining and interrupted cutting.
