Recommended Grades and Chipbreakers Stainless SteelStSaitneleelss
Grades New AC6030M / New AC6040M / AC610M / AC630M / AC520U / AC530U Insert
Selection
AC6030M: Employes "Absotech Platinum", a new CVD coating. The first recommended grade for general machining of stainless
steel that drastically reduces the occurrence of abnormal damage, which is a problem in stainless steel machining.
Achieves long and stable machining thanks to the improved coating strength and excellent adhesion.
AC6040M: Employes "Absotech Bronze", a new PVD coating and exclusive tough carbide substrate. The first recommended
grade for interrupted machining of stainless steel that drastically improves the reliability in unstable machining thanks
to the excellent adhesion and peel-off resistance of the new PVD coating as well as the improved fracture resistance
of the exclusive carbide substrate.
AC610M: High hardness carbide substrate coupled with Super FF Coat. For high efficiency machining with superior wear
resistance.
AC630M: High toughness carbide substrate coupled with Super FF Coat. A general purpose grade with sharp cutting edges for
superior stability.
AC520U: Tough carbide grade that utilises the high wear resistant Super ZX Coat for excellent stability
AC530U: Tough grade with long tool life and high efficiency for precision machining of stainless steel and small components.
