DNMG150608 UC5115
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
| Workpiece Material | Cutting Speed ($v_c$) | Feed Rate ($f$) | Depth of Cut ($a_p$) |
|---|---|---|---|
| Gray Cast Iron (GCI) | 150 - 350 m/min | 0.20 - 0.50 mm/rev | 1.0 - 4.5 mm |
| Nodular Cast Iron (NCI) | 120 - 250 m/min | 0.15 - 0.45 mm/rev | 1.0 - 4.0 mm |
READY TO MOUNT?
This insert fits all standard DDJNR/L, DDNNN, and DDUNR/L tool holders.

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.
