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
Absolutely. Our CNC carbide inserts (including CNMG, WNMG, DNMG, and APMT series) are manufactured strictly adhering to international ISO/ANSI specifications. A CNMG 120408 from OYYU BEYOND will flawlessly fit any standard turning tool holder or indexable tool from major global brands like Sandvik Coromant, Kennametal, Iscar, Walter, or SECO, providing a highly cost-effective premium alternative without sacrificing tolerance or tool life.
We offer optimized CVD and PVD multi-layer coatings for different ISO material groups:
- For Carbon/Alloy Steel (ISO P): Choose our thick multi-layer CVD coated grades (e.g., Al2O3 + TiN). They provide exceptional crater wear resistance and thermal barriers during high-speed dry or wet roughing.
- For Stainless Steel (ISO M): Choose our nano-structured PVD coated grades with sharp, positive chipbreakers (like -TM or -MA). This combination prevents work hardening and effectively controls sticky chips.
The optimal cutting parameters vary depending on the workpiece hardness and operation type:
- For General Steel Turnings: Recommended cutting speed ($V_c$) ranges from 150 to 280 m/min, with a feed rate ($f$) of 0.15 to 0.45 mm/rev.
- For Stainless Steel Finishing: Recommended cutting speed ($V_c$) is 120 to 200 m/min, with a feed rate ($f$) of 0.10 to 0.25 mm/rev.Always adjust parameters based on early wear patterns: increase $V_c$ if built-up edge occurs, or reduce $V_c$ if severe flank wear is observed.
