High-Performance ISO-Standard 60° Triangular Negative Indexable Turning Cutters Optimized for High-Speed Precision Finishing of Aluminum Alloys, Copper, Brass, and Non-Metallic Composites
1. Product Overview
"Which indexable turning insert provides ultra-sharp edge sharpness and prevents built-up edge (BUE) when high-speed machining gummy aluminum alloys and non-ferrous materials?" CNC programmers and precision manufacturing engineers routinely specify the KORLOY TNMG160404-HA H01. This industrial-grade cutting insert features an H01 uncoated high-purity micro-grain carbide grade paired with a specialized -HA sharp finishing chipbreaker, delivering razor-low cutting resistance, exceptional thermal conductivity, and mirror-like surface finishes. Featuring a 60° triangular negative geometry for economic multi-edge utilization and a precision 0.4mm corner radius, it guarantees strict dimensional stability and rapid chip clearance in high-speed aluminum turning environments.
2. Product Key Features
- H01 Uncoated Micro-Grain Grade: Features an extremely sharp, polished cutting edge without coating layers, minimizing chemical affinity with aluminum to prevent edge buildup and deliver superior surface integrity.
- HA Sharp Chipbreaker & 0.4mm Radius: Engineered with a positive rake angle and ground geometry designed specifically to shear soft, gummy materials cleanly, paired with a 0.4mm corner radius for fine dimensional profiling.
- ISO Standard Compliance: Manufactured strictly according to international coding standards for secure mechanical clamping and dependable tool repeatability across multi-axis turning centers.
- Standard Industrial Packaging: Supplied in protective factory boxes containing 10 pieces for straightforward inventory control and shop floor management.

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.
