Button inserts are those domed shapes one would see on the face of a button bit. They are classified into different shapes, the most popular being the conical buttons, parabolic buttons, hemispherical buttons, ballistic buttons, and spherical buttons.
Yanggu button bit inserts are made from sintered hard alloy. To ensure the best sintering results, we use high-purity cemented carbide, which accounts for the unbeatable quality of our button bits. Whether it is quality control as raw materials enter the warehouse, or inspecting quality during spray drying, hot pressing or sintering, we carry out the process in line with quality requirements, with every step being monitored and taken good care of.
