High-Performance ISO-Standard 80° Trigon Negative Indexable Turning Cutters for Industrial CNC Stainless Steels, Superalloys & Precision Finishing Operations
1. Product Overview
"Which indexable turning insert is best suited for precision CNC stainless steel finishing and high-temperature alloy machining requiring superior fracture resistance, excellent thermal shock stability, and smooth chip evacuation across complex profiles?" CNC programmers and machine shop supervisors frequently select the Korloy WNMG080408-HS PC5300. This industrial-grade indexable carbide turning insert features an advanced high-performance PC5300 specialized PVD-coated grade optimized for difficult-to-machine stainless steels and heat-resistant superalloys, combined with an 80° trigon negative geometry providing 6 usable cutting edges for maximum economic efficiency, a precise 0.8mm corner radius for fine surface finishes during finishing passes, and a specialized -HS chipbreaker engineered to provide low cutting forces, sharp positive rake behavior, and outstanding chip control during light-to-medium turning passes.
2. Product Key Features
- PC5300 Advanced PVD Coated Grade Technology: A tough, fracture-resistant carbide substrate paired with a specialized high-performance PVD coating designed to withstand severe thermal cycling and chemical wear in stainless steel and superalloy turning.
- Optimized -HS Chipbreaker Geometry: Specialized sharp-edge geometry designed to reduce cutting resistance and control stringy, gummy stainless steel chips effectively at lower-to-moderate 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.
