Mitsubishi Materials | High-Speed Steel Finishing & Mirror Surface Specialist
Mirror Finishing for Carbon & Alloy Steels
The Mitsubishi VCMT080204-MV NX2525 is a 35° diamond Cermet turning insert engineered for high-speed precision finishing. The NX2525 grade is a non-coated Cermet that provides exceptional chemical stability, effectively preventing Built-Up Edge (BUE). With its 7° positive relief angle and MV (Medium-V) chipbreaker, this long-tail finishing insert is the professional choice for achieving superior surface integrity and mirror-like textures in CNC lathe steel turning and precision boring.

NX2525 Cermet Advantage
The NX2525 Cermet (Ceramic-Metal) grade is Mitsubishi's premier choice for finishing steel. Unlike tungsten carbide, Cermet does not have a high affinity for the workpiece material. This prevents metal sticking to the edge, resulting in much cleaner cuts, high resistance to oxidative wear, and a longer tool life during high-speed finishing operations.
MV Medium-V Chipbreaker
The MV chipbreaker is designed for light-to-medium finishing duties. It provides stable chip control even at low depths of cut. In internal boring, the MV geometry ensures that chips are curled tightly and evacuated easily, protecting the finished internal bore from scratches and thermal damage.

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.
