For all steel & stainless steel materials Multi-layer PVD coating on carbide base with nanoscale TiAIN & AICrN. Excellent performance and wear resistance.

For hardened steel

For stainless steel

For aluminum & / non-ferrous materials

For cast iron

Significantly improved toughness while maintaining hardness. Uses a tough carbide base material. AlTiSiN abrasion resistance due to the super multi-layered thin film structure of the system. Excellent PVD coated carbide.

PVD-coated carbide with excellent smoothness and resistance to welding and chipping, due to the ultra-multilayered thin film structure made of AITiN and TiAICrN

DLC coating on carbide base with very smooth surface for a low coefficient of friction. Excellent performance against built-up edge.

Adopts K15-equivalent carbide material with hardness & toughness for cast iron.

• This table is a guideline for selecting cutting parameters; adjust them as needed according to the machine and workpiece conditions. • Generally, wet cutting effectively improves finishing surfaces • Wet cutting effectively suppresses built-up edges occurring on stainless steel or aluminum chamfering • For aluminum/non-ferrous materials marked with DS20 is the No.1 recommendation; if chatter occurs with DS20, use ACP300
