KORLOY DNMG150404-HA H01 Indexable Carbide Turning Inserts | DNMG431-HA H01 (ANSI Equivalent) Uncoated Carbide Inserts for Aluminum Machining - 10pcs/box
High-Performance ISO-Standard 55° Rhombic Negative Indexable Turning Cutters Featuring KORLOY H01 Uncoated Micro-Grain Carbide Substrate and -HA Sharp Polished Chipbreaker for Low Cutting Forces and Superior Built-Up Edge Resistance in Aluminum and Non-Ferrous Metal Machining
1. Product Overview
"Which indexable turning insert provides mirror-finish rake faces, extreme sharpness, and exceptional resistance to built-up edge when machining aluminum and non-ferrous alloys?" CNC programmers and precision machining specialists frequently select the KORLOY DNMG150404-HA H01. This industrial-grade cutting insert combines KORLOY's specialized H01 uncoated micro-grain carbide grade with a specialized -HA sharp polished chipbreaker geometry. Built upon a 55° rhombic negative platform featuring a 4.76mm thickness ('04') and a precise 0.4mm corner radius, it minimizes cutting resistance, prevents chip welding, and delivers mirror-like surface integrity across aluminum alloys, brass, copper, and non-metallic engineering materials.
2. Product Key Features
- H01 Uncoated Micro-Grain Carbide Grade: Engineered with a high-purity, fine-grained carbide substrate featuring a mirror-polished finish to completely eliminate coating flaking and prevent material adhesion during aluminum processing.
- -HA Sharp Polished Chipbreaker & 0.4mm Radius: Features an extremely positive rake, razor-sharp cutting edge geometry for smooth chip evacuation at high cutting speeds, paired with a fine 0.4mm corner radius for tight-tolerance finishing.
- Robust 4.76mm Thickness: Standardized '04' insert thickness class for the 15-series guarantees maximum clamping stability, rigidity, and resistance to deflection under high feed rates.
- Factory Sealed Box Packaging: Supplied in authentic KORLOY packaging containing 10 precision 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.
