The Original Korloy WNMG060408-HS PC9030 (ANSI: WNMG 332-HS) is a high-performance 80° Trigon Finishing Insert designed for the compact 06-size series. Combining the ultra-sharp HS Chipbreaker with a robust 0.8mm (1/32") radius, this insert excels in achieving superior surface finishes while maintaining edge durability. The PC9030 PVD Grade is the industry leader for Stainless Steel and Super Alloys, preventing chip bonding and ensuring high-precision results in light-to-medium finishing applications.
Sharp & Stable: The HS geometry is engineered for low-force cutting. By utilizing the 0.8mm radius, you gain extra tip strength compared to the 0.4mm version, allowing for slightly higher feed rates without compromising the mirror-like finish required in stainless steel production.

Compatible Tool Holders (Hyperlinks):
Fits all standard tool holders for WNMG 06-size inserts:
- External Turning: MWLNR/L Series (Shank Size 1616/2020)
- Small Boring Bars: S-MWLNR/L Series (Internal Boring)
Core Performance Benefits:
- Advanced PVD Technology: PC9030 provides a smooth coating surface and high toughness substrate to prevent edge chipping on work-hardened materials.
- Reduced Vibration: The sharp rake angle of the HS geometry minimizes radial forces, which is essential for machining thin shafts or deep internal bores.
- 6 Precision Edges: The Trigon geometry offers 50% more cutting edges than standard CNMG inserts, significantly reducing your cost-per-part.

Pro-Tip: Choosing the Right Radius
Use WNMG060404-HS (R0.4) for very light finishing and precision dimensions. Switch to this WNMG060408-HS (R0.8) if you require higher edge strength for semi-finishing or when dealing with slightly irregular surfaces in stainless steel.
