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 |

Shop DCLNR 12 HoldersPro-Tip: MC6015 vs. MC6025
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
When choosing CNC cutting tools, check the full model code, dimensions, grade and selected variant before ordering. Do not rely on the product image alone.
For carbide inserts, tool holders, drills and end mills, compare the mounting dimensions, connection type and manufacturer's specifications with your holder or machine. If you are unsure, share your existing part number and machining application with us before ordering.
Check the product listing for the selling unit, pack quantity and included components. If it is unclear whether the price is per piece or per pack, or whether a tool body and inserts are sold separately, contact us before purchasing.
Select cutting speed, feed rate and depth of cut using the relevant manufacturer's recommendations for your tool model, workpiece material, machine conditions and coolant method. The same settings are not suitable for every product or application.
