The Original Korloy WCKT050308-DA H01 is the powerhouse of the Rich Mill W-Series. Specifically engineered for High-Volume Aluminum Machining, the 05-size insert provides the necessary structural rigidity for aggressive roughing and semi-finishing. Featuring the H01 Ultra-Fine Micro-Grain Carbide, it combines extreme hardness with a razor-sharp, mirror-polished rake face to ensure effortless chip flow and a flawless surface finish on all non-ferrous alloys.
Maximize Metal Removal: When your production demands high MRR (Metal Removal Rate), the WCKT 05 is the answer. Its increased thickness (3.18mm) allows it to handle the higher cutting forces generated during deep pocketing and heavy ramping in aluminum 6061 and 7075.
Technical Specifications:
| ISO Designation | WCKT 050308-DA |
| Insert Size | 05 (Increased Strength) |
| Thickness (S) | 3.18 mm |
| Corner Radius (r) | 0.8 mm |
| Grade | H01 (Mirror Polished Uncoated Carbide) |
| Primary Materials | Aluminum, Copper, Brass, Wood, Acrylic |
Core Performance Benefits:
- Maximum Edge Toughness: The 05 designation provides the thickest carbide substrate in the series, making it highly resistant to cracking during high-speed heavy cuts.
- Mirror-Ground Rake Face: The ultra-smooth surface effectively eliminates friction, preventing the "gumming" effect and built-up edge (BUE) even without high-pressure coolant.
- Aggressive DA Geometry: The high positive rake angle significantly reduces power consumption and cutting heat, protecting the machine spindle during long shifts.
- Precision H-Class Tolerance: Ensures perfect alignment and minimal height deviation between multiple inserts, resulting in high-precision floor finishes.
Recommended Cutting Parameters:
| Workpiece Material | Cutting Speed (Vc) | Feed per Tooth (fz) | Max Depth (ap) |
|---|---|---|---|
| Structural Aluminum (7075) | 600 - 2500 m/min | 0.15 - 0.35 mm/t | Up to 4.5 mm |
| Aluminum Castings (High Si) | 400 - 1000 m/min | 0.12 - 0.28 mm/t | Up to 4.0 mm |
Pro Tip: High-Load Aluminum Milling
The WCKT 05 size is excellent for helical interpolation and ramping. Its thick profile can withstand the varying radial and axial forces better than the 03 or 04 sizes.
When removing large volumes of material, ensure your air blast or coolant is aimed directly at the cutting zone. The DA chipbreaker creates large chips that must be cleared instantly to avoid re-cutting.
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.
