TPMH090204-MV NX2525
Mitsubishi Materials | Precision Steel Finishing Cermet
Mirror Finish Precision with MV Control
The Mitsubishi TPMH090204-MV NX2525 is a high-performance Cermet turning insert designed for high-speed finishing of carbon and alloy steels. Unlike standard carbide, the NX2525 Cermet grade offers superior chemical stability, preventing the "welding" of work material to the edge. This long-tail precision tool, featuring the MV chipbreaker, is the ideal choice for CNC boring where dimensional accuracy and a high-gloss surface finish are paramount.

NX2525 Cermet Grade
NX2525 is a TiCN-based Cermet (Ceramic-Metal). It bridges the gap between the toughness of carbide and the heat resistance of ceramics. It is chemically inert to iron, which means zero Built-Up Edge (BUE) and a consistently high-quality surface finish on all steel workpiece materials.
MV "Multi-Value" Chipbreaker
The MV chipbreaker is designed for versatility. It excels in light-to-medium finishing, offering stable chip control even at fluctuating dephts of cut. Its geometry reduces cutting resistance, which is vital for preventing chatter in internal boring applications.

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.
