Carbide Ball Teeth

Carbide Ball Teeth, also known as carbide ball inserts, tungsten carbide ball teeth, or conical picks, are a specific type of wear part and cutting tool characterized by their hemispherical (ball-shaped) head made of tungsten carbide. They are primarily designed for robust impact, crushing, and grinding applications, rather than precise shearing or slicing. Their unique design allows them to transmit high point load forces into the material, making them ideal for breaking extremely hard and abrasive substances.
