Mitsubishi Materials | The Mirror-Finish Specialist (Left-Hand)
Precision Engineering Overview
The Mitsubishi TPGH110304L-FS NX2525 is a high-performance Left-Hand (L) cermet insert designed for precision finishing. Featuring the advanced NX2525 cermet grade, it offers superior resistance to chemical wear and oxidation compared to standard carbide. The FS chipbreaker is specifically engineered for ultra-fine finishing, making this a critical long-tail precision tool for CNC machining of carbon and alloy steels where a reflective surface luster is required.

NX2525 Cermet Grade
The NX2525 grade is a specialized titanium-cermet material. Cermets offer lower affinity for steel workpieces than carbide, which prevents built-up edge (BUE). This makes it the premier choice for lathe turning operations that require mirror-like surface finishes and high dimensional stability.
FS Super-Finish Breaker
The FS chipbreaker features an exceptionally sharp rake and high positive geometry. It is specifically designed to control chips at light depths of cut, ensuring chip evacuation is clean and does not mar the workpiece surface during CNC boring.

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.
