TPMH090204-MV UE6020
Mitsubishi Materials | High-Performance CVD Coated Steel Turning
The Standard for High-Speed Steel Boring
The Mitsubishi TPMH090204-MV UE6020 is a high-speed CVD coated carbide insert engineered for excellence in steel machining. Featuring a thick Al2O3 (Alumina) layer, the UE6020 grade provides industry-leading thermal stability. Combined with the MV chipbreaker, it is the premier long-tail precision tool for finishing and light-medium CNC boring in Carbon Steels and Alloy Steels.

CVD Grade UE6020
UE6020 is a Chemical Vapor Deposition (CVD) grade designed for high surface speeds. Unlike PVD coatings, the thick layered Alumina structure in UE6020 acts as a massive heat barrier, protecting the carbide substrate from crater wear during prolonged steel turning operations. It is the gold standard for production-scale P-class machining.
MV Multi-Value Geometry
The MV chipbreaker features an optimized rake angle for medium-finishing. It effectively curls chips to prevent tool entanglement, especially critical in automated CNC lathe boring where manual chip clearing is not an option. It provides stable chip control across varying feed rates.

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.
Our automatic quantity discount is 6% off for 2–9 items and 12% off for 10 or more items, based on the total product quantity in the cart. Other offers may not combine with this discount; check the applicable offer conditions.
