2 / Application Range Cutting Speed (m/min) AC61M AC63M AC53U The first recommended grade for general machining of stainless steel drastically reduces the occurrence of abnormal damage in stainless steel machining and achieves stable long tool life thanks to the Absotech Platinum technology. The first recommended grade for general machining of stainless steel drastically improves the reliability in unstable machining thanks to the excellent adhesion and the peeling-off resistance of the new Absotech Bronze technology. The improved fracture resistance of the exclusive carbide substrate assures the production. AC61M Finish and Continuous Continuous to Light Interrupted Cutting Conditions Interrupted to Heavy Interrupted A high efficiency M1 grade featuring improved wear resistance during stainless steel cutting. Employs special, ultra-hard substrate and thin Super FF Coat. Feature The new series of coated grades and chipbreakers recommended as ideal for turning of heavy-cut stainless steel. Absotech Platinum and Absotech Bronze, newly developed technologies, drastically improve peeling-off resistance and provide stable tool life. Extended tool life and thereby reduced tool costs in a wide range of applications, from roughing to finishing and from low-speed to high-speed machining of various types of stainless steel.

The NEM type achieves excellent wear resistance and cutting edge strength while the NEF type and NEG type achieve excellent wear resistance and chip control and ensuring stable machining of stainless steel.,6 Feed Rate (mm/rev) NEF Chipbreaker for The NEF chipbreaker reduces chip curl diameter in finishing applications. Provides very good chip management not fluctuated by the material in use. NEG Chipbreaker for Medium Cutting The NEG chipbreaker achieves excellent wear resistance and chip control from general-purpose machining to roughing applications. Also provides very high versatility. Main chipbreaker that enables good chip control even at low depths of cut. Crater wear advancement is prevented by the round bumps, whilst maintaining excellent control. Sharp edge with 2 rake angle reduces wear. The grooves on the rake face reduce heat and assist chip flow away from the workpiece. The cutting edge maintains the strength slowing the progress of crater wear. Excellent chip management and wear prevention is delivered by the special rake face design.
