TPMN110308 NX2525
Mitsubishi Materials | The Specialist for High-Gloss Steel Finishing
Achieve Mirror-Quality Surfaces
The Mitsubishi TPMN110308 NX2525 is a high-speed Cermet turning insert engineered for precision finishing. The NX2525 grade is a non-coated cermet that provides exceptional chemical stability, effectively preventing Built-Up Edge (BUE). With its 0.8mm corner radius, this long-tail finishing tool provides a robust cutting edge capable of producing high-gloss surface finishes on carbon and alloy steels while maintaining strict dimensional tolerances during CNC boring.

NX2525 Micro-Grain Cermet
NX2525 is a cermet grade that bridges the gap between traditional carbide and ceramics. It features high resistance to plastic deformation and thermal shock. Because it contains metallic binders like nickel, it is tougher than pure ceramics but much harder than carbide, making it the perfect high-speed turning insert for steel finishing.
TPMN Flat-Top Advantage
The TPMN geometry features a flat-top face (no chipbreaker). This provides a stronger cutting edge for stable finishing passes. In high-speed steel turning, the chips naturally break or flow away easily; the absence of a chipbreaker reduces heat concentration at the tip, extending insert tool life.

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.
