TCMT110204 UE6020
Mitsubishi Materials | Versatile CVD Carbide for Steel Machining
The Mitsubishi TCMT110204 UE6020 is a highly versatile CVD coated carbide insert designed for the general turning of carbon and alloy steels. Utilizing the UE6020 grade, this tool provides a robust solution for operations that require a balance between high wear resistance and fracture toughness. As a critical long-tail precision tool, it excels in maintaining edge integrity during medium-to-finishing steel turning applications.

UE6020 Grade: The Balanced Performer
The UE6020 grade is Mitsubishi's all-rounder for steel turning. While UE6110 is optimized for pure speed, UE6020 offers a tougher substrate. This makes it ideal for general machining where the material hardness might vary, or where light interrupted cuts are present. It effectively resists flanking wear and chipping.
Chipbreaker Efficiency
The TCMT geometry provides a positive 7° rake, which reduces friction and heat generation. This indexable turning insert features a specialized chipbreaker geometry that ensures stable chip evacuation even at lower speeds, preventing workpiece damage from stringy chips.

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.
