TN60 Cermet Advantage
The TN60 cermet grade is a non-coated Titanium-based material. Unlike tungsten carbide, cermet has a low affinity for steel, which drastically reduces built-up edge (BUE). This results in high-speed machining stability and an exceptionally long-lasting cutting edge sharpness, perfect for precision finishing operations.
U-Chipbreaker Geometry
The U-Chipbreaker is specifically designed for light finishing to semi-finishing. Its positive rake angle reduces cutting resistance, minimizing vibration on small diameter workpieces. It excels in maintaining chip control even at low depths of cut, ensuring the surface is never scratched by stringy chips during CNC turning.
