CCMT060204 UC5115
Cast Iron Specialist | CVD Black Super Coating | 0.4mm Radius
Material Science & Precision Edge
UC5115 Grade (The Cast Iron Master): Engineered specifically for ISO K (Cast Iron). This grade features a thick CVD (Chemical Vapor Deposition) coating that provides unmatched heat resistance. The "Black Super Coating" technology hardens the surface to resist the abrasive nature of cast iron dust, ensuring long tool life in gray and nodular iron applications.
0.4mm Precision Radius (Optimal Finish): The 04 radius (1/64") is the standard choice for finishing to semi-finishing. It minimizes radial cutting forces, preventing vibration in small-diameter boring operations and delivering a high-quality surface finish on industrial components.
Metric vs. Imperial Comparison
| System | Model Designation | I.C. (Inscribed Circle) | Thickness | Radius (RE) |
|---|---|---|---|---|
| Metric | CCMT060204 | 6.35 mm | 2.38 mm | 0.40 mm |
| Imperial | CCMT21.51 | 1/4" | 3/32" | 0.0157" (1/64") |
Recommended Cutting Parameters
*UC5115 excels at high speeds. Avoid extremely low speeds which may cause coating delamination.
| Workpiece Material | Speed (Vc) | Feed (fn) | Depth (Ap) |
|---|---|---|---|
| Gray Cast Iron (HT) | 150 - 350 m/min | 0.05 - 0.20 mm/r | 0.20 - 1.50 mm |
| Ductile Iron (QT) | 120 - 280 m/min | 0.05 - 0.18 mm/r | 0.20 - 1.20 mm |

UC5115 (CVD Specialist): The Cast Iron Powerhouse. Use this for high-speed, continuous cutting of cast iron. It outlasts universal grades significantly in abrasive materials.
VP15TF (PVD Universal): Only switch to VP15TF if you are performing interrupted cuts or machining a mix of steel and cast iron on the same machine. For pure cast iron production, UC5115 is the superior investment.

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.
