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
When choosing CNC cutting tools, check the full model code, dimensions, grade and selected variant before ordering. Do not rely on the product image alone.
For carbide inserts, tool holders, drills and end mills, compare the mounting dimensions, connection type and manufacturer's specifications with your holder or machine. If you are unsure, share your existing part number and machining application with us before ordering.
Check the product listing for the selling unit, pack quantity and included components. If it is unclear whether the price is per piece or per pack, or whether a tool body and inserts are sold separately, contact us before purchasing.
Select cutting speed, feed rate and depth of cut using the relevant manufacturer's recommendations for your tool model, workpiece material, machine conditions and coolant method. The same settings are not suitable for every product or application.
