TNMG160408-MS UE6020
Mitsubishi Materials | The Versatile Steel Machining Standard
The Mitsubishi TNMG160408-MS UE6020 is a high-performance CVD coated carbide insert designed for versatile steel turning applications. The UE6020 grade is specifically engineered to handle the transition from continuous to interrupted cutting, making it the most reliable indexable turning insert for general-purpose workshop use. Combined with the MS chipbreaker, it delivers exceptional chip control and reduced vibration during CNC machining of carbon and alloy steels.

UE6020 Material Science
The UE6020 grade features a specialized CVD coating with high adhesion strength. This prevents the coating from peeling during unstable cutting or interrupted turning cycles. It is widely considered a long-tail industrial tool essential for shops machining varied carbon and alloy steel components.
MS Chipbreaker Advantage
The MS chipbreaker is designed for medium-light cutting. Its sharp rake geometry reduces cutting resistance and heat generation, effectively preventing built-up edge (BUE) on gummy low-carbon steels while maintaining excellent surface finishes.

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.
