TNMG160408-MA UE6020
Mitsubishi Materials | The Industry Standard for Versatile Steel Turning
The Mitsubishi TNMG160408-MA UE6020 is a highly versatile CVD coated carbide insert designed for stable to lightly interrupted turning of carbon and alloy steels. As a core long-tail precision tool, the UE6020 grade provides an optimized balance of crater wear resistance and edge toughness. The integrated MA chipbreaker is the definitive choice for medium cutting, ensuring excellent chip evacuation in standard CNC machining cycles.

UE6020 Material Grade
The UE6020 grade is Mitsubishi's premier choice for general steel turning. This CVD coated grade features a thick TiCN and Al2O3 layer that provides heat insulation and resists flank wear. It is exceptionally reliable for P25-P35 steel workpieces under varied cutting conditions.
MA Chipbreaker Logic
The MA chipbreaker is engineered for a "medium-range" depth of cut. Its geometry provides a sharp cutting action to reduce cutting forces while maintaining enough strength to prevent edge chipping, making it the most popular indexable turning insert geometry for general lathe work.

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.
