VCMT080202-MV NX2525
Mitsubishi Materials | Ultra-Precision Mirror Finishing Specialist
Extreme Precision for Fine Steel Profiling
The Mitsubishi VCMT080202-MV NX2525 is a 35° diamond Cermet turning insert engineered for high-speed, light-duty finishing. The NX2525 Cermet grade offers superior resistance to built-up edge (BUE) and oxidation, ensuring your workpiece achieves a brilliant, mirror-like texture. Featuring a sharp 0.2mm corner radius and a 7° relief angle, this long-tail finishing insert is the professional choice for intricate external profiles and high-tolerance internal boring in carbon and alloy steels.

NX2525 Cermet Advantage
Cermet technology combines ceramic hardness with metallic toughness. The NX2525 grade is non-coated, providing a sharper cutting edge than PVD/CVD inserts. It is chemically inert to steel, meaning it won't react with the workpiece even at high temperatures, effectively preventing built-up edge and ensuring dimensional stability across long production cycles.
MV Chipbreaker for Fine Finish
The MV (Medium-V) chipbreaker is specialized for low depth-of-cut finishing. When combined with a 0.2mm radius, it ensures that even the thinnest chips are curled and broken away from the surface. This is critical for CNC boring applications where chip wrapping can destroy a finished internal surface.

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.
