The Original Korloy WNMG080412-HS PC9030 (ANSI: WNMG 433-HS) is a unique 80° Trigon Turning Insert that bridges the gap between High Productivity and Precision Finishing. By combining the ultra-sharp HS Chipbreaker with a powerful 1.2mm (3/64") corner radius, this insert allows for significantly higher feed rates without sacrificing the low cutting resistance needed for stainless steel. The PC9030 PVD Grade ensures maximum protection against heat and chemical bonding in 304, 316, and other tough alloys.
Maximize Your Output: The 1.2mm radius offers the strongest edge in the HS series. It is ideal for semi-finishing to finishing passes where you want to push the machine's limits in terms of feed speed while maintaining a smooth, vibration-free cut.
Technical Specifications (ISO Metric vs. ANSI Inch):
| ISO Designation | WNMG 080412-HS |
| ANSI Designation | WNMG 433-HS |
| Corner Radius (r) | 1.2 mm / (3/64") |
| Grade | PC9030 (Premium PVD) |
| Chipbreaker | HS (Sharp Finishing / High-Feed) |
Recommended Cutting Parameters:
Achieve peak efficiency with these recommended parameters for high-performance stainless turning:
| Material Group | Cutting Speed (Vc) | Feed Rate (fn) | Depth of Cut (ap) |
|---|---|---|---|
| 304/316 Stainless Steel | 100 - 180 m/min | 0.15 - 0.40 mm/rev | 0.3 - 2.5 mm |
| High-Temp Super Alloys | 30 - 70 m/min | 0.12 - 0.30 mm/rev | 0.3 - 2.0 mm |
Compatible Tool Holders:
Due to the higher feed potential, we recommend using high-clamping force holders:
- External Turning: MWLNR/L Series (Standard Trigon Holders)
- Internal Boring: S-MWLNR/L Series (Heavy Duty Boring Bars)
Core Performance Benefits:
- Enhanced Edge Security: The 1.2mm radius is far more resistant to chipping than 0.4 or 0.8 versions, making it perfect for semi-roughing to finishing transitions.
- Superior Surface Finish: Despite the large radius, the HS geometry keeps cutting forces low, allowing the tool to glide through material for a mirror finish.
- PVD Anti-Stick Coating: PC9030 technology stops material from welding to the edge, a critical feature for high-feed stainless machining.
- Unbeatable 6-Edge Economy: Provides the lowest cost-per-edge for high-production CNC shops compared to traditional CNMG shapes.

Pro-Tip: When to choose R1.2?
Choose WNMG080412-HS if your machine has the power to handle higher feed rates and you want to reduce cycle times while still maintaining the ultra-low cutting force of the HS chipbreaker. If you are working on small diameters or thin walls, stick with the R0.4 (431) version to minimize radial pressure.
