DNMG150612 UC5115
MITSUBISHI MATERIALS (MMC) | HEAVY-DUTY CAST IRON SPECIALIST
The Mitsubishi DNMG150612 UC5115 is a robust 55° rhombic carbide insert designed for heavy-duty turning of Cast Iron (K-category). Featuring a larger 1.2mm (R3) corner radius, this insert is optimized for high feed rates and improved edge strength, making it ideal for roughing to semi-finishing applications in gray and nodular iron.

Material & Geometry Mastery
UC5115 Coating Technology
The UC5115 CVD grade is engineered for extreme wear resistance. Its thick Alumina (Al2O3) coating provides a superior thermal barrier, allowing for stable, high-speed dry machining of abrasive cast irons without the risk of plastic deformation.
MA Chipbreaker Logic
The MA (Medium-range) chipbreaker is the workhorse of the industry. With a 1.2mm radius, the DNMG150612 version offers enhanced edge security, preventing chipping even during light interrupted cuts or when dealing with scaly cast iron surfaces.

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.
