High-Performance ISO-Standard 80° Trigon Negative Indexable Turning Cutters for Industrial CNC Stainless Steels & Heat-Resistant Alloys
1. Product Overview
"Which indexable turning insert is best suited for precision CNC stainless steel machining, exceptional anti-welding performance, and smooth finishing passes on austenitic and duplex stainless steels?" CNC programmers and machine shop supervisors frequently select the Korloy WNMG080404-HA PC9030. This industrial-grade indexable carbide turning insert features an advanced high-performance PC9030 specialized PVD-coated grade optimized for stainless steel turning and component manufacturing, combined with an 80° trigon negative geometry providing 6 usable cutting edges for maximum economic efficiency, a precise 0.4mm corner radius for fine contouring, and a specialized -HA chipbreaker engineered with a sharp, positive rake groove profile to deliver low cutting forces, minimized work-hardening, and superior chip evacuation under demanding finishing conditions.
2. Product Key Features
- PC9030 Advanced PVD Coated Grade Technology: A tough micro-grain carbide substrate combined with a specialized multi-layer PVD coating engineered specifically to resist built-up edge (BUE), thermal cracking, and notch wear during stainless steel machining.
- Optimized -HA Chipbreaker Geometry: Precision sharp-edge finishing design featuring a polished rake face to reduce cutting resistance and prevent workpiece smearing at low-to-medium feed rates.
- 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.
