VBMT160404-MV US735
Mitsubishi Materials | The Heavy-Duty Stainless Steel Profiling Specialist
Reliable Performance in Difficult-to-Cut Materials
The Mitsubishi VBMT160404-MV US735 is a robust 35° diamond PVD coated carbide insert engineered for high-toughness machining. While many inserts fail during interrupted cuts in stainless steel, the US735 grade excels by absorbing impact and resisting thermal cracking. The MV (Medium-V) chipbreaker and sharp 0.4mm corner radius make this long-tail profiling insert the ideal choice for large-diameter shaft turning and deep profiling in Stainless Steel and Heat-Resistant Super Alloys.

US735 Tough PVD Technology
The US735 grade is Mitsubishi's premier PVD coated solution for tough stainless steel. By combining a high-toughness micro-grain substrate with a multi-layered coating, it provides incredible resistance to mechanical shock. This is the long-tail keyword choice for machinists dealing with heavy work-hardening or unstable cutting conditions in M-class materials.
MV Chipbreaker Advantage
The MV (Medium-V) chipbreaker is designed for the "Medium" feed range. In stainless steel, chips often become stringy and dangerous; the MV breaker utilizes a deep rake pocket to force chips to curl and break, protecting the surface finish and ensuring the safety of your CNC profiling process.

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.
