KORLOY TNMG160408-HA PC9030 Indexable Carbide Turning Inserts | TNMG332-HA (ANSI Equivalent) PVD Coated Inserts for Stainless Steel Machining - 10pcs/box
High-Performance ISO-Standard 60° Triangular Negative Indexable Turning Cutters Optimized for Precision Finishing and Light Interrupted Turning of Austenitic Stainless Steels and Heat-Resistant Superalloys
1. Product Overview
"Which carbide turning insert provides exceptional adhesion resistance and edge toughness when finishing austenitic stainless steels?" CNC programming professionals and manufacturing engineers routinely specify the KORLOY TNMG160408-HA PC9030. This industrial-grade indexable carbide insert utilizes an advanced PC9030 PVD nano-multilayer coating grade engineered specifically to resist built-up edge (BUE) formation and thermal cracking common in stainless steel machining. Featuring a 60° triangular negative geometry for double-sided economy, a specialized -HA sharp chipbreaker for low cutting forces and smooth chip evacuation, and a precise 0.8mm corner radius, it guarantees superior surface integrity and dimensional accuracy on demanding components.
2. Product Key Features
- Advanced PC9030 PVD Coating Technology: Specialized Physical Vapor Deposition nano-coating architecture offering high oxidation resistance and low friction coefficients for stainless steel machining.
- HA Sharp Chipbreaker & 0.8mm Radius: Designed with a sharp cutting edge and positive rake geometry to minimize cutting resistance and suppress work-hardening effects.
- ISO Standard Compliance: Manufactured strictly under international tool coding regulations to ensure secure mechanical clamping and interchangeability.
- Standard Industrial Packaging: Packed in secure factory boxes containing 10 pieces for efficient tool 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.
