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.

8. Frequently Asked Questions (FAQ)
Q: How many inserts are included in one standard box?
A: Each standard factory-sealed box contains exactly 10 pieces of TNMG160408-HA PC9030 inserts.
Q: Why choose PC9030 instead of a CVD grade for stainless steel?
A: PC9030 features a specialized PVD nano-multilayer structure that offers superior toughness and anti-adhesion properties, preventing built-up edge (BUE) formation common when machining stainless steel.
Q: What tool holders are compatible with this TNMG 1604 insert?
A: It is fully compatible with any standard ISO negative turning tool holder featuring a TNMG 1604 pocket size, such as MTJNR or PTJNR series holders.

Technical FAQ & Buying Guide
Absolutely. Our CNC carbide inserts (including CNMG, WNMG, DNMG, and APMT series) are manufactured strictly adhering to international ISO/ANSI specifications. A CNMG 120408 from OYYU BEYOND will flawlessly fit any standard turning tool holder or indexable tool from major global brands like Sandvik Coromant, Kennametal, Iscar, Walter, or SECO, providing a highly cost-effective premium alternative without sacrificing tolerance or tool life.
We offer optimized CVD and PVD multi-layer coatings for different ISO material groups:
- For Carbon/Alloy Steel (ISO P): Choose our thick multi-layer CVD coated grades (e.g., Al2O3 + TiN). They provide exceptional crater wear resistance and thermal barriers during high-speed dry or wet roughing.
- For Stainless Steel (ISO M): Choose our nano-structured PVD coated grades with sharp, positive chipbreakers (like -TM or -MA). This combination prevents work hardening and effectively controls sticky chips.
The optimal cutting parameters vary depending on the workpiece hardness and operation type:
- For General Steel Turnings: Recommended cutting speed ($V_c$) ranges from 150 to 280 m/min, with a feed rate ($f$) of 0.15 to 0.45 mm/rev.
- For Stainless Steel Finishing: Recommended cutting speed ($V_c$) is 120 to 200 m/min, with a feed rate ($f$) of 0.10 to 0.25 mm/rev.Always adjust parameters based on early wear patterns: increase $V_c$ if built-up edge occurs, or reduce $V_c$ if severe flank wear is observed.
