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.
