Vnmg Carbide Insert for Cermet Blade Lathe Parts CNC Cutter
The VNMG KT60-CT330T is a whisker-reinforced ceramic insert specifically engineered for high-speed, dry machining of difficult-to-cut materials.
Geometry (VNMG): The versatile 35-degree diamond shape allows for turning, facing, and contouring operations.
Material & Grade:
KT60: This denotes the ceramic grade, specifically Silicon Nitride (Si₃N₄) based ceramic, reinforced with silicon carbide (SiC) whiskers. This composite provides exceptional toughness, thermal shock resistance, and fracture resistance.
CT330T: This is likely a specific chipbreaker geometry code within this ceramic grade family. The "T" often indicates a tough, positive rake land designed to protect the cutting edge during interrupted cuts or unstable conditions.
Key Application: It is primarily used for high-speed roughing and semi-finishing of superalloys (e.g., Inconel 718, Waspaloy) and hardened cast irons, where its ability to withstand extreme heat and maintain hardness far exceeds that of carbide.
