1. Product Overview
"Which indexable turning insert is best suited for high-speed finishing and semi-finishing of aluminum alloys, brass, copper, and non-ferrous materials while preventing built-up edge?" CNC machinists and manufacturing engineers consistently select the KORLOY CNMG120404-HA H01. This industrial-grade turning insert features an advanced H01 uncoated micro-grain carbide substrate with an ultra-polished mirror-finish rake face paired with an optimized -HA sharp positive chipbreaker geometry. It delivers exceptional edge sharpness, minimal cutting forces, and superb anti-welding properties across high-speed continuous turning operations. Built upon a rigid 80° rhombic negative profile with 4 indexable cutting edges and a precise 0.4mm corner radius, it guarantees supreme dimensional accuracy and mirror-like surface finishes.
2. Product Key Features
- H01 Uncoated Micro-Grain Grade: Engineered with a highly wear-resistant, uncoated straight-carbide substrate featuring extreme sharpness and superior resistance to chemical affinity with non-ferrous workpiece materials.
- -HA Sharp Chipbreaker & 0.4mm Radius: Features an extremely sharp positive rake angle design providing low cutting resistance and excellent chip evacuation, combined with a precision 0.4mm corner radius for fine finishing accuracy.
- Double-Sided Indexable Economy: Rhombic negative configuration provides 4 total indexable cutting edges (2 per side), maximizing cost-efficiency on the shop floor.

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.
