The Original Korloy WNMG060408-HM NC3020 (ANSI: WNMG 332-HM) is the versatile "all-rounder" of the WNMG 06 series. By stepping up to a 0.8mm (1/32") corner radius, this insert offers significantly increased edge strength compared to the 04 size. It is the go-to solution for Steel Turning where productivity is the priority. The NC3020 CVD grade provides the thermal stability needed for high-velocity cutting, making it ideal for both continuous and slightly interrupted passes.
Efficiency & Strength: The R0.8 radius (ANSI 332) allows for higher feed rates while maintaining a stable cutting edge. This makes it particularly effective for removing material quickly in small-to-medium parts or for cleaning up rough internal bores.
Technical Specifications (ISO vs. ANSI):
| ISO Designation | WNMG 060408-HM |
| ANSI Designation | WNMG 332-HM |
| Corner Radius (r) | 0.8 mm / (1/32") |
| Thickness (S) | 4.76 mm / (3/16") |
| Grade | NC3020 (CVD Al2O3 Coated) |
| Chipbreaker | HM (Medium / Universal) |
Core Performance Benefits:
- Robust Cutting Edge: The 0.8mm radius provides a larger surface area to distribute heat and pressure, significantly reducing the risk of premature tip failure.
- Economic 6-Edge Advantage: Maximize your cost-savings. Like all WNMG inserts, this 06-size gives you 6 precision edges, providing a massive advantage over diamond-shaped alternatives.
- Optimized HM Geometry: The HM chipbreaker is designed for reliable chip control at medium depths of cut, preventing long, stringy chips from tangling around the workpiece.
- NC3020 Durability: Korloy's premier steel grade features a specialized coating that resists crater wear and plastic deformation during high-speed CNC operations.
Recommended Cutting Parameters:
| Material | Cutting Speed (Vc) | Feed Rate (fn) | Max Depth (ap) |
|---|---|---|---|
| Carbon Steel (1045) | 180 - 320 m/min | 0.15 - 0.35 mm/rev | 3.0 mm |
| Alloy Steel (4140) | 140 - 280 m/min | 0.12 - 0.30 mm/rev | 2.5 mm |
Why Choose 08 (332) over 04 (331)?
While the 04 radius is excellent for fine finishing, the 08 radius is much better suited for the bulk of your machining. It allows you to run faster feeds to save time and is significantly more forgiving if the material has a rough surface or slightly interrupted features.
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.
