WNMG080408-HA PC9030
High-Feed Finishing | Polished Edge | Stainless Steel Specialist
The Korloy WNMG080408-HA PC9030 (ANSI: WNMG 432-HA) is a premium 80° Trigon turning insert designed for the rigorous demands of Stainless Steel and Heat-Resistant Alloys. Featuring the ultra-sharp, mirror-polished HA geometry and a robust 0.8mm radius, this insert allows for aggressive cycle times while maintaining a vibration-free cut. The PC9030 PVD Grade provides a sophisticated thermal barrier, preventing built-up edge even in high-heat austenitic stainless steels.
Edge Technology
Mirror-polished rake face eliminates chip welding and friction. High positive rake angle shears material with minimal radial force.
Grade Performance
PC9030 PVD coating offers extreme resistance to oxidation and notch wear in 304, 316, and Duplex alloys.

Selection Tip: R0.8 vs R0.4
Use the R0.8 (432) version when you need to increase your productivity. The larger radius allows for higher feed rates while maintaining an excellent surface finish and provides better resistance against edge chipping in slightly interrupted cuts compared to the R0.4 (431) version.
