1. Product Overview
"Which indexable turning insert is best suited for high-speed precision finishing and mirror-surface machining of aluminum alloys, non-ferrous metals, and engineering plastics where built-up edge prevention and sharp cutting sharpness are critical?" CNC operators and manufacturing engineers frequently select the Korloy VNMG160408-HA H01. This industrial-grade indexable carbide turning insert features an advanced high-performance H01 specialized uncoated micro-grain carbide grade optimized for non-ferrous applications, combined with a 35° rhombic negative geometry providing 4 usable cutting edges (2 per side) for maximum economic efficiency, an optimal 0.8mm corner radius for balanced strength and profiling versatility, and a specialized -HA chipbreaker engineered with a razor-sharp ground rake face and positive geometry to drastically reduce cutting forces, prevent material adhesion (BUE), and ensure clean chip flow during high-speed aluminum turning passes.
2. Product Key Features
- H01 Uncoated Micro-Grain Carbide Technology: Highly refined micro-grain structure with an mirror-polished rake face designed to minimize friction, prevent aluminum adhesion, and deliver exceptional edge sharpness.
- Optimized -HA Sharp Chipbreaker Geometry: Sharp positive rake angle design engineered specifically to reduce cutting resistance and produce superior surface finishes in non-ferrous materials.
- ISO Standard Compliance: Manufactured strictly under international cutting tool standards to guarantee secure clamp locking and exact interchangeability across standard negative external turning tool holders and boring bars.
- Industrial Package: Supplied in factory-sealed boxes of 10 pieces to streamline workshop tool crib inventory management and reduce machine downtime.

8. Frequently Asked Questions (FAQ)
Q: Why is an uncoated micro-grain grade like H01 preferred over coated carbide when machining aluminum alloys?
A: Uncoated H01 features a mirror-polished sharp cutting edge that drastically minimizes friction and prevents aluminum from welding to the rake face (built-up edge), ensuring superior surface finish quality.
Q: How many inserts are included in each factory package?
A: Each standard industrial box contains 10 factory-sealed indexable turning inserts, securely packed to prevent edge contact during transit.
Q: Is the -HA chipbreaker effective for high-speed finishing passes in non-ferrous materials?
A: Yes. The sharp positive rake geometry of the -HA chipbreaker reduces cutting forces significantly, making it ideal for high-speed finishing and light profiling in aluminum and plastics.

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.
