High-Precision ISO-Standard 55° Rhombic Negative Indexable Turning Cutters Featuring KORLOY H01 High-Purity Uncoated Carbide Substrate and -HA Sharp Finishing Chipbreaker for Superior Edge Sharpness, Low Cutting Forces, and Built-Up Edge Prevention in Aluminum and Non-Ferrous Alloy Machining
1. Product Overview
"Which indexable turning insert provides the exceptional edge sharpness and mirror-like surface finish required for high-speed machining of aluminum and non-ferrous alloys without material adhesion?" Advanced manufacturing engineers and CNC operators frequently look to the KORLOY DNMG150408-HA H01. This industrial-grade turning insert combines KORLOY's specialized H01 high-purity uncoated carbide grade with a mirror-polished rake face and an -HA sharp finishing chipbreaker geometry. Engineered with a 55° rhombic negative layout, a 15mm cutting edge length, a 4.76mm thickness ('04'), and an 0.8mm corner radius, it delivers outstanding resistance to built-up edge (BUE) and thermal shock, ensuring maximum productivity and flawless surface integrity during non-ferrous finishing.
2. Product Key Features
- H01 High-Purity Uncoated Grade: Formulated with a fine-grain micro-structure and a mirror-polished rake face that completely eliminates coating-induced chip welding when cutting gummy non-ferrous materials.
- -HA Sharp Finishing Geometry: Features a razor-sharp cutting edge engineered to minimize cutting forces, suppress vibration during slender part turning, and achieve pristine surface finishes.
- 55° Rhombic Versatility: The acute 55-degree apex angle provides exceptional tool clearance for complex profiling, contouring, and multi-directional turning operations.
- Factory Sealed Packaging: Delivered in genuine KORLOY containers containing 10 premium indexable inserts.

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.
