The Original Korloy WNMG080408-HA H01 (ANSI: WNMG 432-HA) is a high-productivity 80° Trigon Turning Insert engineered specifically for Aluminum, Copper, and Non-Ferrous alloys. Featuring the elite H01 Uncoated Grade with a Mirror-Polished surface, this insert effectively eliminates the most common issue in aluminum machining: chip welding (Built-up Edge). The 0.8mm (1/32") radius provides enhanced edge strength, allowing you to maximize material removal rates without sacrificing surface integrity.
Maximum Material Removal: The HA chipbreaker is characterized by its high positive rake angle and sharp cutting edge. Combined with the robust R0.8 radius, it provides the stability needed for high-feed aluminum turning while ensuring a vibration-free, clean cut.
Technical Specifications (ISO vs. ANSI):
| ISO Designation | WNMG 080408-HA |
| ANSI Designation | WNMG 432-HA |
| Corner Radius (r) | 0.8 mm / (1/32") |
| Grade | H01 (Polished Sub-micron Carbide) |
| Primary Material | Aluminum, Copper, Brass, Plastics |
Cutting Parameters (Recommended):
Achieve peak efficiency in non-ferrous materials with these parameters:
| Material Group | Cutting Speed (Vc) | Feed Rate (fn) | Depth of Cut (ap) |
|---|---|---|---|
| Aluminum Alloys | 350 - 900 m/min | 0.15 - 0.40 mm/rev | 0.5 - 4.5 mm |
| Brass / Copper | 180 - 450 m/min | 0.15 - 0.35 mm/rev | 0.5 - 3.5 mm |
Core Performance Benefits:
- Mirror-Like Rake Face: The extreme polish reduces the coefficient of friction, allowing chips to flow away instantly and maintaining tool sharpness for longer periods.
- Enhanced Edge Security: The R0.8 radius provides a significantly tougher cutting point than R0.4, making it ideal for heavier cuts or slightly interrupted surfaces in cast aluminum.
- Ultra-Sharp HA Geometry: Engineered to slice through soft materials, minimizing heat generation and preventing work-piece deformation.
- 6-Edge Trigon Economy: Get 50% more productivity out of every insert compared to standard CNMG shapes—lowest cost-per-edge for high-volume production.

Pro-Tip: Choosing the Right Radius
Choose WNMG080408-HA (R0.8) for general turning where you want to increase your feed rate and maximize chip removal. If you are doing fine finishing, small intricate details, or working with thin-walled parts, consider the WNMG080404-HA (R0.4) version to minimize radial cutting pressure.
Packaging: 10 pieces per box.
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.
