TPMH110308-MV UE6020
Mitsubishi Materials | High-Speed CVD Steel Specialist
Edge Strength for High-Volume Production
The Mitsubishi TPMH110308-MV UE6020 is a high-performance CVD coated carbide insert engineered for stable, high-speed turning of steel. Utilizing a multi-layer coating with a thick Alumina thermal shield, the UE6020 grade thrives in continuous cutting where heat management is critical. With a reinforced 0.8mm corner radius, this long-tail steel specialist tool offers maximum durability and longer tool life during CNC boring of Carbon Steels and Alloy Steels.

UE6020 CVD Layering
The UE6020 grade utilizes Chemical Vapor Deposition (CVD) to apply a thick Alumina shield. This coating is far more heat-resistant than PVD coatings, making it ideal for high-speed turning. It prevents plastic deformation of the cutting edge even during long continuous runs in Alloy Steels.
MV "Multi-Value" Chipbreaker
The MV chipbreaker is designed for finishing and semi-finishing. With the larger 0.8mm radius, it allows for a higher depth of cut (DOC) and feed rates while maintaining excellent chip evacuation, which is vital for preventing chip buildup in deep internal boring cycles.
Recommended Cutting Parameters
| Material Group | Speed ($v_c$) | Feed ($f$) | DOC ($a_p$) |
|---|---|---|---|
| Low Carbon Steel | 150 - 320 m/min | 0.10 - 0.25 mm/rev | 0.5 - 2.5 mm |
| Alloy Steel (Medium Hard) | 120 - 250 m/min | 0.08 - 0.20 mm/rev | 0.3 - 2.0 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.
