VBMT110304-MV US735
Mitsubishi Materials | The Tough Stainless Steel Profiling Expert
Superior Toughness for Interrupted & Gummy Cuts
The Mitsubishi VBMT110304-MV US735 is a 35° diamond PVD coated carbide insert specifically developed for machining Stainless Steel (M-class). The US735 grade features high fracture toughness and a smooth coating layer to combat thermal cracking and Built-Up Edge (BUE). Equipped with the MV (Medium-V) chipbreaker and a 0.4mm corner radius, this long-tail stainless turning insert provides reliable performance in semi-finishing applications and difficult-to-cut alloys.

US735 Tough PVD Coating
The US735 grade is Mitsubishi's premier solution for stainless steel machining. This PVD coated grade is specifically designed for toughness to prevent edge chipping during interrupted cuts. It features a high resistance to plastic deformation, making it the best long-tail insert for tough austenite stainless steels (304, 316) that tend to work-harden quickly.
MV Chipbreaker Performance
The MV (Medium-V) chipbreaker is an all-rounder. For gummy materials like stainless steel, chip control is the biggest challenge. The MV geometry creates a stable "chip-breaking pocket" that prevents long stringy chips from scratching the surface finish or wrapping around the spindle during CNC profiling.
Recommended Cutting Parameters

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.
