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
When choosing CNC cutting tools, check the full model code, dimensions, grade and selected variant before ordering. Do not rely on the product image alone.
For carbide inserts, tool holders, drills and end mills, compare the mounting dimensions, connection type and manufacturer's specifications with your holder or machine. If you are unsure, share your existing part number and machining application with us before ordering.
Check the product listing for the selling unit, pack quantity and included components. If it is unclear whether the price is per piece or per pack, or whether a tool body and inserts are sold separately, contact us before purchasing.
Select cutting speed, feed rate and depth of cut using the relevant manufacturer's recommendations for your tool model, workpiece material, machine conditions and coolant method. The same settings are not suitable for every product or application.
