CNMG120408-MA MC6015
High-Velocity Steel Specialist | Nano-Texture CVD Grade | MA Chipbreaker
Next-Gen Productivity: The MC6015 Edge
MC6015 Grade (Nano-Texture Technology): The MC6015 is Mitsubishi's most advanced CVD grade for P-Class (Steel). It features a unique crystal orientation within the coating that provides incredible resistance to crater wear and plastic deformation. This grade is specifically engineered to perform at cutting speeds that would destroy general-purpose inserts, making it ideal for high-volume automated production.
MA Chipbreaker (The Versatile Standard): The MA geometry is a medium-cut chipbreaker designed with a optimized rake angle. It provides a perfect balance between edge strength and sharpness, ensuring that even at extremely high speeds, chip evacuation remains consistent and controlled to prevent surface marring.
0.8mm (1/32") Balanced Radius: The 08 radius is the industry's versatile standard. It offers the structural integrity required for medium roughing while still being capable of producing superior surface finishes during final passes in high-speed applications.

Recommended Cutting Parameters
*The MC6015 grade is optimized for high-speed continuous cutting. Ensure maximum rigidity in your setup.
| Workpiece Material | Speed (Vc) | Feed (fn) | Depth (Ap) |
|---|---|---|---|
| Carbon Steel (1045 / S45C) | 280 - 450 m/min | 0.15 - 0.45 mm/r | 0.50 - 4.50 mm |
| Alloy Steel (4140 / 4340) | 220 - 380 m/min | 0.12 - 0.35 mm/r | 0.50 - 3.50 mm |

MC6015 (High Speed): The ultimate choice for stable, continuous turning. It offers the highest wear resistance at high temperatures.
MC6025 (Universal): Choose MC6025 if your machining involves light interrupted cuts or if you are working with less stable setups where toughness is more critical than pure speed.

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.
