Product Feature

“SKS EXTREME” EXSKS type, next-generation high feed machining cutter Possible high feed machining with fz=2mm/t at max. depth of cut (ap)=3mm.

Economical double-sided insert (6 corners).

Insert thickness of 7.5mm has improved strength of 1.5 times when compared to conventional tool.

Stable high feed machining possible with long reach over L/D=6.

Excellent ramping and helical interpolation, and high efficient pocket milling. *Max. ramping angle 3° is possible with 2 1/2” (63mm) diameter.

Insert adopting new PVD coated grade “JC7560” with improved fracture toughness and achieving longer tool life.

Notes:1. The figures should be adjusted according to the machine and work rigidity.2. If chattering occurs, reduce the DOC (AP) or RPM by 30% and keep the feed per tooth the same.3. If machine does not have enough power, the DOC (AP) or spindle speed should be reduced by 30%.4. Use air instead of coolant.
