Korloy WNMG080404-HM NC6110 (WNMG 431-HM) Cast Iron Turning Insert (10pcs)
Price shown is a starting point. Contact us for a precise quote based on your requirements.
The Original Korloy WNMG080404-HM NC6110 (ANSI: WNMG 431-HM) is a specialized 80° Trigon Turning Insert engineered exclusively for Cast Iron Machining. Featuring the advanced NC6110 CVD Grade, this insert offers extreme hardness and exceptional abrasion resistance when processing Gray Cast Iron (GG) and Ductile Iron (GGG). With its precise 0.4mm (1/64") radius, it is the premier choice for automated production lines requiring high surface finish and tight dimensional tolerances.
The Cast Iron Specialist: NC6110 is optimized to combat the abrasive nature of cast iron. Its ultra-hard coating structure allows for significantly higher cutting speeds while extending tool life and reducing downtime for insert changes.
Technical Specifications (ISO vs. ANSI):
| ISO Designation | WNMG 080404-HM |
| ANSI Designation | WNMG 431-HM |
| Corner Radius (r) | 0.4 mm / (1/64") |
| Grade | NC6110 (Cast Iron CVD) |

Cutting Parameters (Recommended):
Achieve peak performance for NC6110 grade with these recommended starting parameters:
| Material Group | Cutting Speed (Vc) | Feed Rate (fn) | Depth of Cut (ap) |
|---|---|---|---|
| Gray Cast Iron | 250 - 550 m/min | 0.10 - 0.30 mm/rev | 0.5 - 3.5 mm |
| Ductile Iron | 180 - 400 m/min | 0.10 - 0.25 mm/rev | 0.5 - 3.0 mm |
Compatible Tool Holders:
Ensure maximum rigidity by pairing this insert with high-quality tool holders:
- External Turning: MWLNR/L Series (Standard 80° Trigon)
- Internal Boring: S-MWLNR/L Series (High-Rigidity Boring Bars)
Core Performance Benefits:
- Extreme Abrasion Resistance: Engineered specifically for the high-heat, high-friction environment of cast iron machining to prevent crater wear.
- Precision Mirror Finish: The R0.4 radius reduces cutting forces, preventing vibration on slender workpieces while delivering a superior surface finish.
- 6-Edge Cost Efficiency: The Trigon shape provides 6 usable cutting edges, drastically lowering your cost-per-part compared to standard 4-edge diamond inserts.

Grade Selection Pro-Tip
NC6110 vs. NC6210: NC6110 is the "Wear-Resistant" flagship, best for stable, high-speed continuous cutting. If your application involves heavy impacts or interrupted cuts, we recommend the tougher NC6210 grade to prevent edge chipping.
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.
