WNMG080408-GR NC6210
HEAVY ROUGHING SPECIALIST | HIGH-SPEED STEEL MACHINING
The Korloy WNMG080408-GR NC6210 (ANSI: WNMG 432-GR) is engineered for maximum metal removal rates (MRR) in Steel. The GR Chipbreaker features a reinforced cutting edge designed to withstand high mechanical stress during heavy roughing and interrupted cuts. Coupled with the NC6210 CVD Grade, which offers industry-leading heat resistance and high-speed wear protection, this insert is built for the most demanding CNC production environments.

Pro Tip: NC6210 vs NC6215
NC6210: Best for Continuous High-Speed Steel Turning. It offers the highest wear resistance for mass production.
NC6215: Choose this for Heavy Interrupted Cuts or unstable setups. It offers higher toughness to prevent cracking under impact.

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.
