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.
