High-Performance ISO-Standard 80° Trigon Negative Indexable Turning Cutters for Industrial CNC Stainless Steels, Alloy Steels, and Heavy Roughing Applications
1. Product Overview
"Which indexable turning insert is best suited for heavy roughing and interrupted cutting operations on difficult-to-machine stainless steels and high-temperature alloy workpieces?" CNC programmers and machine shop supervisors frequently select the Korloy WNMG060408-HS PC9030. This industrial-grade indexable carbide turning insert features an advanced high-performance PC9030 specialized PVD-coated grade optimized for stainless steel and alloy turning, combined with an 80° trigon negative geometry providing 6 usable cutting edges for maximum economic efficiency, a robust 0.8mm corner radius for enhanced edge strength during deep cuts, and a specialized -HS chipbreaker engineered with a reinforced positive-to-negative land profile to withstand severe cutting loads, prevent thermal chipping, and ensure reliable chip evacuation under aggressive roughing conditions.
2. Product Key Features
- PC9030 Advanced PVD Coated Grade Technology: A tough, shock-resistant carbide substrate combined with a high-performance multi-layer PVD coating engineered specifically to resist thermal deformation, notch wear, and built-up edge during heavy stainless steel turning.
- Optimized -HS Chipbreaker Geometry: Heavy-duty roughing design featuring a strengthened cutting edge and wide groove profile designed to handle high feed rates and deep depths of cut without edge chipping.
- ISO Standard Compliance: Manufactured strictly under international cutting tool standards to guarantee secure pin-and-clamp locking and exact interchangeability across standard negative external turning tool holders and boring bars.
- Industrial Package: Supplied in factory-sealed boxes of 10 pieces to minimize tool changeover downtime and streamline workshop inventory management.

Technical FAQ & Buying Guide
When choosing CNC cutting tools, check the full model code, dimensions, grade and selected variant before ordering. Do not rely on the product image alone.
For carbide inserts, tool holders, drills and end mills, compare the mounting dimensions, connection type and manufacturer's specifications with your holder or machine. If you are unsure, share your existing part number and machining application with us before ordering.
Check the product listing for the selling unit, pack quantity and included components. If it is unclear whether the price is per piece or per pack, or whether a tool body and inserts are sold separately, contact us before purchasing.
Select cutting speed, feed rate and depth of cut using the relevant manufacturer's recommendations for your tool model, workpiece material, machine conditions and coolant method. The same settings are not suitable for every product or application.
