DNMG150604-GK MC5015
Mitsubishi Materials | High-Speed Cast Iron Machining Master
The Mitsubishi DNMG150604-GK MC5015 is a premium 55° rhombic negative turning insert engineered for the high-efficiency machining of Cast Iron (K-category). By utilizing Mitsubishi’s proprietary Nano-Texture CVD coating technology, the MC5015 grade provides unparalleled wear resistance. Combined with the GK chipbreaker, this insert excels in stable cutting conditions, delivering precision and longevity in gray and ductile iron applications.
Technical Specifications
| ISO Designation (Metric) | DNMG150604-GK |
|---|---|
| ANSI Designation (Inch) | DNMG 441-GK |
| Material Grade | MC5015 (Nano-Texture CVD) |
| Thickness | 6.35 mm (1/4") |
| Corner Radius | 0.4 mm (1/64") |
MC5015 Grade Technology
The MC5015 grade is optimized for high-speed continuous turning. The Nano-Texture Al2O3 coating ensures uniform crystal growth, providing a harder surface that resists crater wear and heat buildup during long production runs in abrasive cast irons.
GK Chipbreaker Profile
The GK chipbreaker is the first choice for stable Cast Iron (K) turning. It features a robust land area that enhances cutting edge strength, effectively managing chips even when machining brittle materials like Gray Cast Iron (GCI).
Optimization: Cutting Parameters
| Material Group | Cutting Speed ($v_c$) | Feed Rate ($f$) |
|---|---|---|
| Gray Cast Iron (GCI) | 200 - 450 m/min | 0.10 - 0.40 mm/rev |
| Ductile Cast Iron (FCD) | 150 - 300 m/min | 0.10 - 0.35 mm/rev |
CNC MACHINE COMPATIBILITY
This insert is compatible with all standard 15-size (1/2" IC) tool holders: DDJNR/L, DDNNN, or DDUNR/L.

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.
