The Original Korloy CCMT120404-HMP NC6110 is a premium turning insert specifically engineered for high-efficiency machining of Cast Iron. While steel inserts struggle with the abrasive nature of iron, the NC6110 grade features an ultra-hard CVD coating that provides exceptional wear resistance. The size-12 substrate combined with a precision 0.4mm nose radius ensures maximum stability and a superior surface finish on large cast iron workpieces.
Tech Note: NC6110 is optimized for Cast Iron (K-class). For Carbon Steel or Alloy Steel, we recommend the NC3120 Series.

Cast Iron Grade Tip: NC6110 vs. NC6210
Optimizing your cast iron production:
The best choice for continuous, high-speed turning. Maximum wear resistance in stable conditions.
Better for interrupted cuts or older castings with uneven surfaces. Offers more toughness.
Machinist's Tip: When machining Cast Iron, NC6110 can often be used dry (without coolant) due to its superior heat resistance.
Packaging: 10 pieces per box.
