Korloy WCKT06T308-DA H01 Heavy-Duty Mirror Polished Milling Insert for Aluminum (10pcs)
Price shown is a starting point. Contact us for a precise quote based on your requirements.
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
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.
