Korloy WNMG080404-HA H01 (WNMG 431-HA) Aluminum Turning Insert (10pcs)
Price shown is a starting point. Contact us for a precise quote based on your requirements.
The Original Korloy WNMG080404-HA H01 (ANSI: WNMG 431-HA) is a high-performance 80° Trigon Turning Insert specifically engineered for Aluminum and Non-Ferrous Metals. Featuring the H01 Uncoated Grade, this insert undergoes a specialized Mirror Polishing process to minimize friction and prevent chip welding. The HA Chipbreaker is designed with an ultra-sharp cutting edge, ensuring high-precision results and an incredible surface finish on soft, "sticky" materials.
The Aluminum Specialist: H01 is the gold standard for non-ferrous machining. Its sub-micron substrate and polished rake face allow chips to slide off effortlessly, eliminating "built-up edge" and ensuring consistent mirror-like finishes on aluminum and copper alloys.
Technical Specifications (ISO vs. ANSI):
| ISO Designation | WNMG 080404-HA |
| ANSI Designation | WNMG 431-HA |
| Corner Radius (r) | 0.4 mm / (1/64") |
| Grade | H01 (Uncoated Polished Carbide) |

Recommended Cutting Parameters:
H01 allows for extremely high cutting speeds in non-ferrous materials:
| Material | Cutting Speed (Vc) | Feed Rate (fn) | Depth of Cut (ap) |
|---|---|---|---|
| Aluminum Alloys | 400 - 1000 m/min | 0.10 - 0.30 mm/rev | 0.5 - 4.0 mm |
| Copper / Brass | 200 - 500 m/min | 0.10 - 0.25 mm/rev | 0.5 - 3.0 mm |
Compatible Tool Holders:
Maximize your aluminum turning efficiency with these high-performance holders:
- External Turning: MWLNR/L Series (80° Trigon Standard)
- Internal Boring: S-MWLNR/L Series (Aluminum Internal Machining)
Core Performance Benefits:
- Mirror Polished Surface: The ultra-smooth top face reduces friction, which prevents heat buildup and the adhesion of "gummy" aluminum.
- Ultra-Sharp HA Edge: The high positive rake angle "shears" the material rather than rubbing it, resulting in lower power consumption and better surface integrity.
- Superior Sub-micron Substrate: Provides the edge toughness required for continuous high-speed runs while resisting chemical wear.
- 6-Edge Trigon Geometry: Delivers 50% more productivity per insert compared to CNMG shapes, significantly reducing the cost-per-part in high-volume aluminum production.

Machining Pro-Tip
Why Uncoated? For aluminum machining, H01 (Uncoated) is often superior to coated inserts because the coating process can dull the cutting edge. H01 maintains an extremely sharp edge and, combined with its polished surface, provides the best defense against material welding on the tool.
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.
