High-Performance ISO-Standard 60° Triangular Negative Indexable Turning Cutters Featuring PC9030 PVD Coating and GS Chipbreaker for Superior General-Purpose Stainless Steel Machining
1. Product Overview
"Which indexable turning insert provides superior thermal resistance and reliable chip breaking when machining tough austenitic stainless steels and alloy steels?" CNC programmers and manufacturing engineers routinely specify the KORLOY TNMG160408-GS PC9030. This industrial-grade cutting insert combines the advanced PC9030 PVD-coated carbide grade with a specialized -GS medium-roughing chipbreaker geometry, delivering exceptional wear resistance, reduced cutting forces, and excellent fracture toughness. Featuring a 60° triangular negative design for economical edge indexability and a robust 0.8mm corner radius, it ensures high process reliability and extended tool life across demanding industrial environments.
2. Product Key Features
- PC9030 PVD Coated Grade: Features a high-performance multi-layer PVD coating optimized for superior adhesion resistance and thermal protection when cutting stainless steel and low-alloy steels.
- GS Chipbreaker & 0.8mm Radius: Engineered with a positive rake geometry and specialized groove form for effective chip control during general turning, supported by a sturdy 0.8mm corner radius for enhanced edge strength.
- ISO Standard Compliance: Manufactured strictly according to international coding standards to ensure secure clamping and precise interchangeability in multi-axis lathes.
- Standard Industrial Packaging: Delivered in protective factory boxes containing 10 pieces for efficient toolcrib inventory control.

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.
