CCMT120412 UC5115
Roughing Powerhouse | Black Super CVD Coating | 1.2mm Impact Radius
Material Science & Edge Reinforcement
UC5115 Grade (The CVD Shield): Specifically optimized for ISO K (Cast Iron) production. The thick-layer CVD (Chemical Vapor Deposition) technology utilizes a Black Super Coating top layer. This provides extreme hardness to resist the abrasive "sand-paper" effect of gray iron and the heat generated during dry cutting.
1.2mm Corner Radius (Maximum Security): The 12 (3/64") radius is built for Roughing and Heavy Semi-Finishing. It offers the thickest cross-section at the cutting tip, allowing the tool to plunge into rough casting surfaces and scale without breaking. It also allows for significantly higher feed rates (fn) while maintaining edge integrity.
Metric vs. Imperial Comparison
| System | Model Designation | I.C. (Inscribed Circle) | Thickness | Radius (RE) |
|---|---|---|---|---|
| Metric | CCMT120412 | 12.70 mm | 4.76 mm | 1.20 mm |
| Imperial | CCMT433 | 0.500" (1/2") | 0.187" (3/16") | 0.0469" (3/64") |
Recommended Cutting Parameters
*The 1.2mm radius generates higher cutting forces. Ensure maximum machine rigidity and high horsepower.
| Cast Iron Group | Speed (Vc) | Feed (fn) | Depth (Ap) |
|---|---|---|---|
| Gray Iron (FC300) | 180 - 450 m/min | 0.20 - 0.45 mm/r | 0.80 - 4.50 mm |
| Ductile Iron (FCD) | 120 - 280 m/min | 0.15 - 0.35 mm/r | 0.80 - 3.50 mm |
Required Tool Holder
Optimized for SCLCR/L 12 series external holders and heavy-duty bars:
Shop SCLCR 12 HoldersPro-Tip: UC5115 vs UE6110
UC5115 (Iron King): Thick CVD coating designed specifically to handle the high abrasion of cast iron. Use this for 100% of your iron work.
UE6110 (Steel Grade): Never use UE6110 in cast iron. While it is a great CVD grade, the chemistry is designed for steel chips; it will wear out 5x faster than **UC5115** when faced with cast iron dust.
