Mitsubishi Materials | The Specialist for High-Efficiency Cast Iron Turning
The Mitsubishi TNMA160412 UC5115 is a heavy-duty CVD coated carbide insert engineered for high-performance turning of Gray and Ductile Cast Iron. Utilizing the UC5115 grade with optimized alumina coating, this insert provides extreme thermal protection and crater wear resistance. The 1.2mm nose radius combined with a flat-top (No Chipbreaker) design makes it the definitive long-tail industrial tool for high-feed roughing and stable finishing in K-class materials.

UC5115 CVD Turning Grade
The UC5115 grade is a specialized CVD turning insert material featuring a thick layer of Al2O3. This provides superior heat insulation when machining abrasive cast iron. This grade is optimized for stable turning in high-speed, continuous cutting conditions where flank wear resistance is vital.
TNMA Flat-Top Geometry
The TNMA geometry is a flat-top design (no chipbreaker) that provides maximum cross-sectional strength for this indexable turning insert. Because cast iron produces brittle chips, the flat-top design is ideal, offering a robust edge that resists chipping even under heavy interrupted loads or variable casting skins.

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.
