VBMT160404-MV UE6020
Mitsubishi Materials | High-Speed Steel Turning & Medium Profiling
Heavy-Duty Profiling for Alloy & Carbon Steels
The Mitsubishi VBMT160404-MV UE6020 is a heavy-duty 35° diamond CVD coated carbide insert designed for high-efficiency turning. The 16mm edge length allows for deeper profiling passes compared to the 11mm series. Utilizing the UE6020 grade, this insert provides superior crater wear resistance during continuous high-speed steel machining. The MV chipbreaker ensures smooth chip evacuation, making it a premier long-tail CNC turning tool for both semi-finishing and medium roughing of various steel grades.

UE6020 CVD Steel Grade
The UE6020 grade is a CVD-coated workhorse designed for the P10-P30 steel group. It features a thick Alumina and Titanium Nitride layer that acts as a thermal shield. This allows for significantly higher cutting speeds ($v_c$) than PVD inserts while maintaining exceptional resistance to plastic deformation, especially during continuous dry machining.
MV Medium-V Chipbreaker
The MV chipbreaker is specifically designed for the "Medium" range of steel turning. Its unique wave-form rake profile breaks chips effectively at both light and heavy feed rates. This versatility makes it the best chipbreaker for profiling shafts or deep bores where chip accumulation could lead to tool failure.
Recommended Cutting Parameters
| Material Group | Speed ($v_c$) | Feed ($f$) | DOC ($a_p$) |
|---|---|---|---|
| Carbon Steel (A36/1045) | 150 - 320 m/min | 0.12 - 0.35 mm/rev | 0.5 - 3.5 mm |
| Alloy Steel (4140/4340) | 120 - 260 m/min | 0.10 - 0.30 mm/rev | 0.5 - 3.0 mm |

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.
