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
When choosing CNC cutting tools, check the full model code, dimensions, grade and selected variant before ordering. Do not rely on the product image alone.
For carbide inserts, tool holders, drills and end mills, compare the mounting dimensions, connection type and manufacturer's specifications with your holder or machine. If you are unsure, share your existing part number and machining application with us before ordering.
Check the product listing for the selling unit, pack quantity and included components. If it is unclear whether the price is per piece or per pack, or whether a tool body and inserts are sold separately, contact us before purchasing.
Select cutting speed, feed rate and depth of cut using the relevant manufacturer's recommendations for your tool model, workpiece material, machine conditions and coolant method. The same settings are not suitable for every product or application.
