DNMG150408-MS US735
Impact Resilience | Anti-Work Hardening | MS Sharp Edge Geometry
The Ultimate Solution for Interrupted Cuts
The DNMG150408-MS US735 is engineered for the most punishing environments in CNC turning. In high-production environments, searching for a Mitsubishi DNMG150408-MS price that reflects its value is easy once you see the tool life in interrupted cuts.
US735 Grade (High-Toughness PVD): This grade is the "Heavy-Hitter" of the Mitsubishi family. It utilizes a high-toughness carbide substrate that acts as a shock absorber. The PVD coating is specifically designed to resist the chemical welding (Built-Up Edge) common when machining 300-series Stainless Steels and high-temp alloys.
MS Chipbreaker (Medium-Sharp Specialist): The MS geometry is significantly sharper than standard "Universal" geometries. This sharpness is critical for preventing work hardening in stainless steel. By slicing through the material with less force, the MS chipbreaker ensures the workpiece surface remains stable for subsequent operations.
Metric vs. Imperial Comparison
| System | Model Designation | I.C. (Inscribed Circle) | Thickness | Radius (RE) |
|---|---|---|---|---|
| Metric | DNMG150408-MS | 12.70 mm | 4.76 mm | 0.80 mm |
| Imperial | DNMG432-MS | 1/2" | 3/16" | 0.0315" (1/32") |
Recommended Cutting Parameters
*The 0.8mm radius allows for robust feed rates. Adjust speeds downward for heavy interruptions.
| Workpiece Material | Speed (Vc) | Feed (fn) | Depth (Ap) |
|---|---|---|---|
| 304/316 Stainless Steel | 60 - 130 m/min | 0.12 - 0.35 mm/r | 0.80 - 3.50 mm |
| Tough Alloy Steels (4140) | 80 - 160 m/min | 0.15 - 0.40 mm/r | 1.00 - 4.00 mm |
Pro-Tip: US735 vs. VP15TF
US735 (The Interrupted Specialist): If you are turning hex bar, parts with keyways, or uneven castings, US735 is mandatory. It prevents the catastrophic fracture that ends production.
VP15TF (The Precision Expert): For clean, continuous CNC turning in stable conditions, switch to VP15TF. It offers higher wear resistance at higher RPMs but cannot match the impact strength of US735.

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.
