These tungsten carbide inserts are designed for versatile CNC lathe applications, including turning, milling, grooving, threading, and drilling across different workpiece materials such as steel, stainless steel, and cast iron.
For steel machining (Class P), you can choose grades like YC330 for high-speed finishing, YC331 or YC333 for general purpose steel processing, and YC332 for light rough to rough machining.
Our manufacturing integrates advanced spray tower granulation, automatic electric press suppression, full overpressure PVC sintering, and ultrasonic cleaning to ensure precise dimensions and uniform structural integrity.
We apply advanced coatings including MT-TiCN + thick AL2O3 + TiN for class P steel grades, and TiAlN / TiAlSIN multi-layer coatings for high toughness requirements in stainless steel and alloy metal machining.
For cast iron (Class K), the YC531 grade is recommended for general nodular and gray cast iron processing, while YC532 is preferred for rough machining tasks due to its optimal balance of wear resistance and toughness.
Yes, our inserts are designed to correspond with standard international grades and specifications (such as GC4015, UE6020, VP15TF, etc.), making them widely compatible with standard CNC insert holders.
