DNMG150404-MS US735
Precision Impact Mastery | Tough US735 Grade | MS Anti-Vibration Geometry
Engineered for Unstable Stainless Steel Conditions
US735 Grade (The Toughness Standard): The US735 is Mitsubishi's premier high-toughness PVD grade. Designed specifically for Stainless Steel, it features a specialized coating that withstands the high temperatures of gummy alloys while the substrate remains flexible enough to absorb the shock of Interrupted Cuts. It is the definitive grade for preventing sudden edge breakage.
MS Chipbreaker (The Finishing Specialist): The MS (Medium-Sharp) geometry features a micro-sharp cutting edge. This is crucial for Austenitic Stainless Steel (300 series), as it slices the material rather than pushing it, significantly reducing Work Hardening. This ensures that the next pass is as smooth as the first, protecting your overall tool life.
0.4mm Radius (Tight Dimensional Control): The "04" (1/64") radius is the choice for precision finishing. It reduces radial pressure during the cut, which is essential for maintaining accuracy on long, slender shafts or thin-walled components where deflection is a concern.

Recommended Cutting Parameters
*Optimized for finishing. Maintain lower speeds for high-nickel alloys to manage heat.
| Material Group | Speed (Vc) | Feed (fn) | Depth (Ap) |
|---|---|---|---|
| 304 / 316 Stainless Steel | 60 - 150 m/min | 0.05 - 0.20 mm/r | 0.20 - 1.50 mm |
| Duplex / Super Alloys | 40 - 80 m/min | 0.08 - 0.15 mm/r | 0.30 - 1.20 mm |

US735 (The Heavy-Duty Toughness): Essential for finishing passes on parts with cross-holes, keyways, or if your machine lacks rigidity. It prevents micro-cracking at the tip.
VP15TF (The Continuous Speedster): Switch to VP15TF only for clean, high-speed continuous CNC finishing. It offers better thermal wear resistance but will chip more easily if it hits an interruption.

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.
