MITSUBISHI MATERIALS | PREMIUM CAST IRON TURNING SERIES
The Mitsubishi DNMG150608 UC5115 is a high-performance 55° rhombic negative turning insert, specifically engineered for the demanding world of Cast Iron (K-class) machining. Leveraging Mitsubishi Materials' proprietary CVD coating technology, this insert excels in high-speed continuous to light interrupted cutting, providing unparalleled tool life and surface finish quality.
Technical Specifications
| Metric Specification | DNMG150608 (R0.8) |
| ANSI/Inch Equivalent | DNMG 442 |
| Material Grade | UC5115 (CVD Coated) |
| Application Range | Gray Cast Iron / Ductile Iron |
UC5115 Grade Technology
The UC5115 grade features a thick Al2O3 (Alumina) layer combined with a specialized TiCN layer. This combination offers extreme thermal protection and crater wear resistance. It is the industry standard for stable machining of GCI and NCI at high surface speeds.
MA Chipbreaker Geometry
The MA Chipbreaker (Medium-range cutting) is designed for versatile performance. Its edge strength is optimized to handle the abrasive nature of cast iron while maintaining excellent chip control across various depths of cut.
Recommended Cutting Parameters
