KORLOY TNMG160408-HA H01 Indexable Carbide Turning Inserts | TNMG332-HA (ANSI Equivalent) Uncoated Inserts for Non-Ferrous Machining - 10pcs/box
High-Performance ISO-Standard 60° Triangular Negative Indexable Turning Cutters Optimized for Mirror-Finish Machining of Aluminum Alloys, Copper, Brass, and Non-Metallic Composites
1. Product Overview
"Which carbide turning insert delivers mirror-like surface finishes and prevents built-up edge when machining aluminum and non-ferrous metals?" CNC programming professionals and manufacturing engineers routinely specify the KORLOY TNMG160408-HA H01. This industrial-grade indexable carbide insert utilizes a specialized H01 uncoated micro-grain carbide grade engineered specifically with extreme edge sharpness and high wear resistance for non-ferrous applications. Featuring a 60° triangular negative geometry for double-sided economy, a specialized -HA sharp chipbreaker for low cutting forces and superior chip flow, and a precise 0.8mm corner radius, it guarantees exceptional dimensional accuracy and eliminates burrs on aluminum components.
2. Product Key Features
- Specialized H01 Uncoated Micro-Grain Grade: High-purity carbide substrate designed with extreme edge sharpness to prevent material adhesion and built-up edge (BUE) during soft metal machining.
- HA Sharp Chipbreaker & 0.8mm Radius: Engineered with a polished rake face and sharp cutting geometry to minimize cutting resistance and optimize surface finish quality.
- ISO Standard Compliance: Manufactured strictly under international tool coding regulations to ensure secure mechanical clamping and precise 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 H01 inserts.
Q: Why is the H01 grade uncoated when most inserts have PVD or CVD coatings?
A: Uncoated micro-grain carbide provides the extreme edge sharpness required to cleanly shear soft non-ferrous materials like aluminum and prevents workpiece smearing or built-up edge.
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.
