Korloy CCMT120404-HMP NC6110 High-Speed Cast Iron Turning Insert (10pcs)
Price shown is a starting point. Contact us for a precise quote based on your requirements.
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.

Recommended Cutting Parameters:
| Workpiece Material | Cutting Speed (Vc) | Feed Rate (f) | Depth of Cut (ap) |
|---|---|---|---|
| Grey Cast Iron (GG25) | 200 - 450 m/min | 0.10 - 0.30 mm/rev | 0.5 - 3.0 mm |
| Ductile Iron (GGG40/50) | 150 - 350 m/min | 0.10 - 0.25 mm/rev | 0.5 - 2.5 mm |
Compatible Tool Holders:
To maximize stability during high-speed iron turning, pair this CCMT 12 insert with heavy-duty SCLCR/L holders:
- External Turning: SCLCR2020K12 / SCLCR2525M12
- Boring Bars (Internal): S20R-SCLCR12 / S25S-SCLCR12 / S32T-SCLCR12
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.
Technical FAQ & Buying Guide
Absolutely. Our CNC carbide inserts (including CNMG, WNMG, DNMG, and APMT series) are manufactured strictly adhering to international ISO/ANSI specifications. A CNMG 120408 from OYYU BEYOND will flawlessly fit any standard turning tool holder or indexable tool from major global brands like Sandvik Coromant, Kennametal, Iscar, Walter, or SECO, providing a highly cost-effective premium alternative without sacrificing tolerance or tool life.
We offer optimized CVD and PVD multi-layer coatings for different ISO material groups:
- For Carbon/Alloy Steel (ISO P): Choose our thick multi-layer CVD coated grades (e.g., Al2O3 + TiN). They provide exceptional crater wear resistance and thermal barriers during high-speed dry or wet roughing.
- For Stainless Steel (ISO M): Choose our nano-structured PVD coated grades with sharp, positive chipbreakers (like -TM or -MA). This combination prevents work hardening and effectively controls sticky chips.
The optimal cutting parameters vary depending on the workpiece hardness and operation type:
- For General Steel Turnings: Recommended cutting speed ($V_c$) ranges from 150 to 280 m/min, with a feed rate ($f$) of 0.15 to 0.45 mm/rev.
- For Stainless Steel Finishing: Recommended cutting speed ($V_c$) is 120 to 200 m/min, with a feed rate ($f$) of 0.10 to 0.25 mm/rev.Always adjust parameters based on early wear patterns: increase $V_c$ if built-up edge occurs, or reduce $V_c$ if severe flank wear is observed.
