The Cast Iron Master | CVD Black Super Coating | 0.4mm Radius
Material & Edge Technology
UC5115 Grade (CVD Coating): This is a dedicated ISO K (Cast Iron) grade. It utilizes a thick CVD coating with a "Black Super" top layer that minimizes crater wear and edge erosion caused by the high abrasive content of cast iron. It is designed for high-speed continuous cutting where thermal stability is critical.
0.4mm Precision Radius (Standard Finish): The 04 (1/64") radius is the industry favorite for semi-finishing to finishing. It creates low radial cutting forces, which helps maintain tight tolerances and a high surface finish, especially in internal boring operations where tool deflection must be avoided.
Metric vs. Imperial Comparison
| System | Model Designation | I.C. (Inscribed Circle) | Thickness | Radius (RE) |
|---|---|---|---|---|
| Metric | CCMT09T304 | 9.525 mm | 3.97 mm | 0.40 mm |
| Imperial | CCMT32.51 | 0.375" (3/8") | 0.156" (5/32") | 0.0157" (1/64") |
Recommended Cutting Parameters
*UC5115 thrives in high-speed, dry-cutting environments typical for cast iron processing.
| Material Group | Speed (Vc) | Feed (fn) | Depth (Ap) |
|---|---|---|---|
| Gray Cast Iron | 180 - 400 m/min | 0.05 - 0.20 mm/r | 0.20 - 1.50 mm |
| Nodular (Ductile) Iron | 120 - 280 m/min | 0.05 - 0.18 mm/r | 0.20 - 1.20 mm |

UC5115 (CVD): The Cast Iron Specialist. It is built to endure the high-speed friction and abrasiveness of gray iron. It outlasts universal grades significantly in stable production.
VP15TF (PVD): Switch to VP15TF only for interrupted cuts or when you need to machine a mix of steel and iron on a small CNC lathe. For high-volume iron parts, **UC5115** is the cost-effective champion.

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.
