Get Started with Stainless Steel Milling
The machinability of stainless steels differs depending on alloying elements, heat treatment, manufacturing process, whether the material is forged or casted, and more.
Milling – Initial Considerations
Milling has evolved into a machining method with a very broad range of operations. Carefully consider configurations before milling.

GC1040
Tough, thin-coated PVD grade for finishing to roughing in unstable to stable, wet or dry conditions. Good choice for complex tool paths and sticky materials.
GC2040
Tough, medium-thick coated CVD grade designed for tough and demanding, medium to rough milling applications with poor stability in dry conditions. High feed rates, large diameters and radial engagements.
S30T
Medium-hard, thin-coated PVD grade to be used as a complement to GC1040 when stability is good and for high cutting speed demands in wet and dry conditions.
GC2030
Medium-hard, thin coated PVD grade for light roughing to finishing. Complement to GC1040 in good stability, for high cutting speeds in dry conditions.
