The Original Korloy WNMG080408-HM NC3120 (ANSI: WNMG 432-HM) is a next-generation 80° Trigon Turning Insert engineered for high-performance steel machining. Featuring the advanced NC3120 CVD Grade, this insert is the upgraded successor to the classic NC3020, offering superior thermal stability and wear resistance at even higher cutting speeds. With its robust 0.8mm (1/32") radius, it is the industry standard for versatile semi-finishing to medium roughing of various steel alloys.
Maximize Your Efficiency: NC3120 represents the pinnacle of Korloy's steel turning technology. It is specifically designed for automated production lines where high-speed stability and long-term tool life are critical for reducing downtime.
Technical Specifications (ISO vs. ANSI):
| ISO Designation | WNMG 080408-HM |
| ANSI Designation | WNMG 432-HM |
| Corner Radius (r) | 0.8 mm / (1/32") |
| New Grade | NC3120 (Advanced High-Speed CVD) |
| Chipbreaker | HM (Universal Medium Cut) |
Compatible Tool Holders:
To achieve the best results, we recommend using these standard industrial tool holders:
- External Turning Holders: MWLNR/L Series (Standard 80° Trigon)
- Internal Boring Bars: S-MWLNR/L Series (Internal Boring)
Recommended Cutting Parameters:
Optimize your CNC performance with these recommended settings for NC3120 grade:
| Material Group | Cutting Speed (Vc) | Feed Rate (fn) | Depth of Cut (ap) |
|---|---|---|---|
| Low/Medium Carbon Steel | 220 - 450 m/min | 0.15 - 0.45 mm/rev | 1.0 - 4.5 mm |
| Alloy Steel (Pre-hardened) | 180 - 350 m/min | 0.12 - 0.35 mm/rev | 1.0 - 3.5 mm |
Core Performance Benefits:
- Next-Generation Coating: The NC3120 grade features an enhanced multi-layer Al2O3 coating that significantly increases resistance to crater and flank wear.
- Exceptional Economy: The 6-edge Trigon design provides 50% more cutting edges than standard CNMG inserts, lowering your cost-per-part.
- Stable Chip Control: The HM geometry handles a wide range of cutting depths, ensuring consistent chip breaking even at high feed rates.

Grade Selection Pro-Tip
NC3120 vs NC3020: While NC3020 is a proven performer for general steel turning, NC3120 is optimized for High-Speed Stability. If your CNC machines are running at maximum capacity and you need better resistance to heat-related wear, NC3120 is the superior choice for high-volume automated production.
