WNMG080404-HA PC9030
Ultimate Precision: Polished Edge for Stainless Steel & Super Alloys
The Original Korloy WNMG080404-HA PC9030 (ANSI: WNMG 431-HA) is a specialized 80° Trigon insert engineered for Precision Finishing. The HA Chipbreaker features a mirror-polished rake face and an ultra-sharp cutting edge, specifically designed to slice through "sticky" materials like 304/316 Stainless Steel and Inconel. Powered by the PC9030 PVD Grade, this insert provides the ultimate barrier against chemical bonding and thermal deformation.
Core Engineering Benefits
- ✓ Zero-Friction Edge: Polished HA geometry prevents built-up edge (BUE), ensuring consistent dimensional accuracy.
- ✓ PVD PC9030 Grade: High-toughness sub-micron substrate with superior oxidation resistance for high-temperature alloys.
- ✓ Chatter Suppression: Sharp positive rake angle significantly reduces radial forces, ideal for slender workpieces.
- ✓ 6 Precision Edges: Trigon geometry provides 50% more productivity per insert compared to standard CNMG shapes.

Required Tooling Interface:
Expert Selection: PC9030 vs. PC5300
PC9030: The specialist. Use this for dedicated stainless steel production. It provides better anti-welding properties than PC5300.
PC5300: The generalist. Choose this if you switch between steel and stainless steel on the same machine and need higher edge toughness for interrupted cuts.
