The Original Korloy WCKT040208-DA H01 is a high-performance W-Style Milling Insert specifically engineered for High-Metal Removal Rates (MRR) in Aluminum and Non-Ferrous Alloys. With an upgraded thickness and size compared to the 03 series, the WCKT 04 allows for deeper axial cuts while maintaining the signature Mirror Finish that Korloy's H01 Uncoated Grade is famous for. The DA Chipbreaker provides a razor-sharp slicing action, essential for reducing heat and preventing material adhesion.
Engineered for Speed: The WCKT040208-DA is the go-to choice for CNC machinists who need to push their spindle to the limit. Its balanced geometry reduces centrifugal forces and cutting vibration, making it ideal for high-speed machining (HSM) centers.
Technical Specifications:
| ISO Designation | WCKT 040208-DA |
| Insert Shape | W-Style (Trigon) |
| Corner Radius (r) | 0.8 mm |
| Grade | H01 (Sub-micron Polished Carbide) |
| Target Materials | Aluminum Alloys, Copper, Plastics, Wood |
Core Performance Benefits:
- Enhanced Structural Strength: The 04 size provides more carbide mass, allowing for aggressive ramping and pocketing without risking insert breakage.
- Micro-Polished Rake Face: Reduces friction coefficient to the absolute minimum, ensuring chips slide off instantly and preventing the dreaded "built-up edge" on the tip.
- Exceptional Sharpness: The DA geometry features a sharp cutting edge that minimizes burr formation, especially on thin-walled aluminum components.
- Extreme Accuracy: Precision-ground H-class tolerance ensures high repeatability and minimal run-out when using multi-insert milling cutters.
Recommended Cutting Parameters:
| Workpiece Material | Cutting Speed (Vc) | Feed per Tooth (fz) | Max Depth (ap) |
|---|---|---|---|
| Wrought Aluminum (6061) | 500 - 2000 m/min | 0.12 - 0.30 mm/t | Up to 3.5 mm |
| Cast Aluminum (High Si) | 300 - 800 m/min | 0.10 - 0.25 mm/t | Up to 3.0 mm |
Pro Tip: Aluminum Profiling Mastery
Because aluminum transfers heat quickly, maintaining high feed rates (fz) is actually beneficial. It helps carry the heat away within the chip, protecting the insert's edge from softening.
For a final finishing pass, try a very light depth of cut (0.1 - 0.2 mm) at high RPM. The R0.8 radius combined with the polished DA breaker will produce a mirror-like shine.
Packaging: 10 pieces per box.
