Taper button bits have higher technology, much longer primary drilling time and higher drilling efficiency. According to the tungsten carbide insert, button bits can be divided into types of hemispherical, conical and parabolic button, etc.
Button bits with hemispherical button is for high bearing capacity and abrasive resistance while conical button and parabolic button are for high drilling speed and low abrasive resistance.
Our tapered button bit was from high quality cemented carbide and produced with heat treatment technology, which connected with tapered drill rod well for air leg or hand-held rock drill machine for drilling holes in gold and coal mining, marble and granite quarries, stone project, tunnel, water conservancy, etc.
