UE6020 Grade: The All-Rounder
The UE6020 grade is Mitsubishi's premium CVD solution for general steel turning. It features a specialized tough substrate that prevents edge chipping during light interrupted cuts. The multi-layer coating provides a hard barrier against thermal cracking, making it the ideal indexable turning insert for carbon steel and alloy steel workshops.
Robust 0.8mm Radius
The 0.8mm nose radius ($RE$) offers significantly higher edge strength compared to 0.4mm alternatives. It allows for more aggressive feed rates and improved heat dissipation. This makes the TCMT16T308 perfect for semi-finishing and finishing where stable machining and productivity are the priority.
Recommended Cutting Data

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.
