The Original Korloy WNMG080404-HM NC3120 (ANSI: WNMG 431-HM) represents the next generation of 80° Trigon Steel Turning technology. Engineered to surpass the performance of the classic NC3020, the NC3120 grade features an enhanced Al2O3 coating structure that offers superior heat dissipation and crater wear resistance. Combined with the 0.4mm (1/64") radius, this insert is the ultimate tool for Precision Finishing in high-volume, automated steel production environments.
The Future of Steel Machining: NC3120 is designed for workshops that demand higher Vc (cutting speed) without compromising tool life. Its optimized surface treatment reduces friction, preventing "built-up edge" even when machining gummy low-carbon steels.
Technical Specifications (ISO Metric vs. ANSI Inch):
| ISO Designation | WNMG 080404-HM |
| ANSI Designation | WNMG 431-HM |
| New Grade | NC3120 (Advanced High-Speed CVD) |
| Corner Radius (r) | 0.4 mm / (1/64") |
| Coating Technology | Premium Multi-Layer Al2O3 + TiN |
Compatible Tool Holders (Hyperlinks):
Ensure maximum precision by using the standard industrial tool holder series:
- External Turning: MWLNR/L Series (80° Trigon Standard)
- Internal Boring: S-MWLNR/L Series Boring Bars
Core Performance Benefits:
- Extreme High-Speed Stability: The NC3120 coating allows for 20-30% higher cutting speeds than conventional grades, drastically reducing cycle times.
- Precision Finishing Edge: The R0.4 radius minimizes radial cutting pressure, preventing deflection and ensuring micron-level accuracy on slender parts.
- Next-Level Heat Shield: Advanced thermal barrier technology keeps the carbide core cool, preventing plastic deformation even in dry machining conditions.
- Economic 6-Edge Design: Still the champion of cost-efficiency, giving you 6 usable edges per insert to lower your tooling overhead.
Recommended Cutting Parameters:
