Korloy WNMG080408-HM PC9030 (WNMG 432-HM) Stainless Steel Turning Insert (10pcs)
Price shown is a starting point. Contact us for a precise quote based on your requirements.
The Original Korloy WNMG080408-HM PC9030 (ANSI: WNMG 432-HM) is a high-performance 80° Trigon Turning Insert specifically optimized for Stainless Steel and Heat-Resistant Alloys. Utilizing the premier PC9030 PVD Grade, this insert provides a sharp cutting edge and excellent toughness to combat work-hardening and chip-bonding. The 0.8mm (1/32") radius offers the perfect balance of edge strength and material removal rates for medium machining operations.
Built for Toughness: PC9030 is Korloy’s flagship PVD grade for the M-series (Stainless Steel). Its smooth coating prevents built-up edge (BUE), ensuring consistent performance even in gummy materials or light interrupted cuts.

Compatible Tool Holders:
Ensure a rigid setup for high-feed stainless machining by using these compatible tool holders:
- External Turning: MWLNR/L Series (80° Trigon Standard)
- Internal Boring: S-MWLNR/L Series Boring Bars
Core Performance Benefits:
- Sub-micron Substrate: Provides superior edge stability and resistance against mechanical shock and sudden fracture.
- Enhanced Surface Quality: The HM chipbreaker geometry is designed for optimal chip breaking in gummy materials, preventing "bird-nesting" during long cuts.
- Trigon Economy: Offers 6 precision cutting edges per insert, delivering 50% more value than standard 4-edge diamond (CNMG) inserts.

Grade Comparison Pro-Tip
PC9030 vs. NC3120: Use NC3120 for high-speed Steel turning in stable conditions. Switch to PC9030 whenever you machine Stainless Steel or need higher toughness for interrupted cuts in various materials.
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.
