DNMG150404 UC5115
High-Speed Cast Iron Specialist | UC5115 CVD Grade | Precision Finishing
Engineered for Abrasive Iron Machining
Machinists looking for the best Mitsubishi DNMG150404 UC5115 price know that the value lies in its longevity. Cast iron turning creates massive abrasive wear and heat; the UC5115 is built to endure these exact conditions.
UC5115 Grade (The Iron Workhorse): The UC5115 CVD grade for cast iron features a thick, multi-layered Alumina (Al2O3) coating. This provides extreme thermal protection and crater wear resistance. It is specifically designed to handle the silica and graphite inclusions found in Gray Cast Iron (K10-K20) and Ductile Iron (K10-K25).
0.4mm Radius (Tight Tolerance Finishing): The "04" (1/64") radius is optimized for high-precision CNC finishing. It reduces radial cutting pressure, which is critical when turning thin-walled cast iron components or achieving fine surface finishes on large bores.
Metric vs. Imperial Comparison
| System | Model Designation | I.C. (Inscribed Circle) | Thickness | Radius (RE) |
|---|---|---|---|---|
| Metric | DNMG150404 | 12.70 mm | 4.76 mm | 0.40 mm |
| Imperial | DNMG431 | 1/2" | 3/16" | 0.0157" (1/64") |
Recommended Cutting Parameters
*UC5115 thrives at high speeds. Avoid extremely low RPMs to prevent built-up edge on nodular iron.
| Workpiece Material | Speed (Vc) | Feed (fn) | Depth (Ap) |
|---|---|---|---|
| Gray Cast Iron (HT250/FC250) | 200 - 450 m/min | 0.10 - 0.25 mm/r | 0.20 - 2.00 mm |
| Nodular/Ductile Iron (FCD) | 150 - 300 m/min | 0.10 - 0.20 mm/r | 0.30 - 1.50 mm |

UC5115 (The Iron Master): Specifically tuned for the high carbon content of cast iron. It has superior abrasion resistance compared to steel grades.
UE6110/UE6020 (The Steel Choice): These are for steel. If you use UC5115 on steel, it may chip prematurely due to the difference in chip welding properties. Use CVD coated inserts for cast iron only on K-group materials for maximum ROI.

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.
