Cast Iron Specialist | Black Super CVD Coating | 0.8mm High-Feed Radius
Material Science & Edge Security
UC5115 Grade (CVD Mastery): This grade is engineered specifically for ISO K (Cast Iron) materials. Utilizing a thick-layer CVD coating, it provides incredible hardness and heat resistance. The specialized "Black Super Coating" acts as a thermal barrier, protecting the carbide substrate from the abrasive micro-particles inherent in gray and ductile irons.
0.8mm Radius (Productivity Choice): The 08 radius (1/32") offers a significantly stronger cutting edge than the 02 or 04 versions. It allows for increased feed rates and deeper depths of cut. This geometry is perfect for removing "skin" from cast parts and maintaining edge integrity during continuous high-speed runs.
Metric vs. Imperial Comparison
| System | Model Designation | I.C. (Inscribed Circle) | Thickness | Radius (RE) |
|---|---|---|---|---|
| Metric | CCMT060208 | 6.35 mm | 2.38 mm | 0.80 mm |
| Imperial | CCMT21.52 | 1/4" | 3/32" | 0.0315" (1/32") |
Recommended Cutting Parameters
*UC5115 thrives in dry or wet high-speed environments. Use the 0.8mm radius to push your cycle times.
| Workpiece Material | Speed (Vc) | Feed (fn) | Depth (Ap) |
|---|---|---|---|
| Gray Iron (HT250/300) | 180 - 380 m/min | 0.12 - 0.35 mm/r | 0.50 - 2.00 mm |
| Ductile Iron (QT450/600) | 140 - 300 m/min | 0.10 - 0.28 mm/r | 0.50 - 1.80 mm |

UC5115 (CVD): Optimized for High-Speed Iron. The thick coating is built for the abrasiveness of cast iron. It will outperform any universal grade by 2x-3x in pure iron applications.
VP15TF (PVD): Switch to VP15TF only if you are dealing with heavy interruptions (like holes or slots) or if you are machining small batches of steel and iron on the same setup.

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.
