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.
