The Original Korloy WCKT06T308-DA H01 is the largest and most robust insert in the Rich Mill W-Series. Engineered for Heavy-Duty Industrial Aluminum Machining, the 06T3 specification offers maximum structural integrity with a 3.97mm thickness. This insert is the ultimate choice for large-scale aerospace, automotive, and mold base production where removing massive volumes of aluminum (6000 & 7000 series) in the shortest time is critical. The H01 Grade provides the legendary mirror-polished finish required to prevent chip welding in high-load scenarios.
The Heavyweight Champion: With a reinforced substrate and the longest cutting edge in the series, the WCKT 06T3 allows for aggressive axial depths of cut and high-speed ramping that would compromise smaller inserts. It is designed for spindles with high torque and high rigidity.
Technical Specifications:
| ISO Designation | WCKT 06T308-DA |
| Insert Size / Thickness | 06T3 (3.97 mm Thickness) |
| Corner Radius (r) | 0.8 mm |
| Grade | H01 (Premium Uncoated Polished Carbide) |
| Target Materials | All Aluminum Alloys, Copper, Brass, Non-Ferrous Alloys |
Core Performance Benefits:
- Maximum Metal Removal Rate (MRR): The large profile and thick carbide body allow for significantly deeper cuts (ap) and faster feed rates (fz) compared to standard sizes.
- Extreme Anti-Stick Coating-Free Surface: The H01 mirror-finish polishing technology ensures that chips slide off the rake face effortlessly, eliminating the thermal buildup caused by friction.
- Reinforced DA Geometry: The DA chipbreaker is optimized to provide a sharp, clean cut that reduces cutting pressure, preventing deflection even in heavy roughing passes.
- Industrial-Grade Stability: Built to withstand the vibration and heat of 24/7 high-production environments without losing edge sharpness.
Recommended Cutting Parameters:
| Workpiece Material | Cutting Speed (Vc) | Feed per Tooth (fz) | Max Depth (ap) |
|---|---|---|---|
| Aerospace Alum (7075) | 800 - 3000 m/min | 0.15 - 0.40 mm/t | Up to 5.5 mm |
| Copper / Bronze | 300 - 800 m/min | 0.12 - 0.30 mm/t | Up to 4.5 mm |
Pro Tip: Heavy-Duty Aluminum Mastery
The WCKT 06T3 is designed for high-performance machines (BT50, HSK100). Ensure the workpiece is securely clamped, as the high feed rates can generate significant axial forces.
For maximum metal removal, use through-spindle coolant or high-volume flood coolant to flush out the large chips created by the 06T3's deep cutting capability.
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.
