CCMT09T308 UC5115
Cast Iron Productivity Specialist | Black Super CVD Coating | 0.8mm Radius
Material Science & Edge Toughness
UC5115 Grade (The Iron Master): Specifically engineered for ISO K (Cast Iron). This grade utilizes a thick CVD (Chemical Vapor Deposition) coating with a specialized "Black Super" top layer. It is built to survive the high temperatures and abrasive dust of gray, nodular, and ductile irons, providing significantly longer tool life than universal PVD grades in high-speed continuous cutting.
0.8mm Roughing Radius: The 08 (1/32") radius is designed for High Metal Removal Rates (MRR). It offers superior edge security, allowing the insert to withstand the "skin" of cast parts and handle aggressive feed rates without chipping.
Metric vs. Imperial Comparison
| System | Model Designation | I.C. (Inscribed Circle) | Thickness | Radius (RE) |
|---|---|---|---|---|
| Metric | CCMT09T308 | 9.525 mm | 3.97 mm | 0.80 mm |
| Imperial | CCMT32.52 | 0.375" (3/8") | 0.156" (5/32") | 0.0315" (1/32") |
Recommended Cutting Parameters
*The 0.8mm radius thrives under high feed loads. Maintain rigid tool clamping for best results.
| Cast Iron Type | Speed (Vc) | Feed (fn) | Depth (Ap) |
|---|---|---|---|
| Gray Iron (HT250) | 200 - 450 m/min | 0.12 - 0.35 mm/r | 0.50 - 2.50 mm |
| Ductile Iron (QT500) | 150 - 300 m/min | 0.10 - 0.28 mm/r | 0.50 - 2.00 mm |

UC5115 (CVD): The Cast Iron Powerhouse. Thick coating built for high-speed friction. Use this for stable, high-production gray and ductile iron machining.
VP15TF (PVD): Switch to VP15TF only for heavy interruptions (holes/slots) or if you are machining a mix of steel and iron in a small shop environment.

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.
