Mitsubishi Materials | The Specialist for High-Efficiency Cast Iron Turning
The Mitsubishi TNMG160412 UC5115 is a high-performance CVD coated carbide insert engineered for heavy-duty turning of Gray and Ductile Cast Iron. Utilizing the UC5115 grade with a thick Alumina ($Al_2O_3$) layer, this insert provides extreme thermal protection and crater wear resistance. The large 1.2mm nose radius makes it a definitive long-tail industrial tool for high-feed roughing and stable finishing in abrasive K-class materials.

UC5115 CVD Turning Grade
The UC5115 grade is a specialized CVD turning material. It balances extreme hardness with enough toughness to handle light interruptions. This indexable turning insert is the first choice for machining cast iron components where heat-induced wear is the primary concern.
TNMG Robust Geometry
The double-sided TNMG geometry provides 6 usable cutting edges, offering excellent cost-performance for CNC machining. The 1.2mm radius on this model ensures the cutting edge remains stable under high feed rates, reducing the risk of edge chipping on abrasive casting skins.
Recommended Cutting Parameters

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.
