NX2525 Cermet Technology
The NX2525 Cermet grade is a titanium-based material that offers exceptional resistance to oxidation and built-up edge (BUE). Cermet stays sharper longer than carbide at high speeds, making it the premier choice for lathe turning operations that require "as-polished" surface quality.
FS Chipbreaker Geometry
The FS chipbreaker is an ultra-sharp geometry optimized for super-finishing. It provides excellent chip control even at extremely low feed rates and shallow depths of cut, essential for high-precision components and light boring applications.
Recommended Cutting Parameters
| Workpiece Material | Speed ($v_c$) | Feed ($f$) | DOC ($a_p$) |
|---|---|---|---|
| Carbon/Alloy Steel | 150 - 300 m/min | 0.03 - 0.12 mm/rev | 0.05 - 0.5 mm |
COMPATIBLE BORING BARS
This Left-Hand (L) insert requires Left-Hand boring bars or turning holders, typically STFPL or STGPL series.
