Product Description
Taper button bit as small hole bit is different with thread button bit as long hole bit to use taper match with bit with rod to be used for air leg or hand held jack hammer driller in quarrying,and mining.
The series is the main variety in the international series of bits. The diameter of the bit is in the range of D32-D65mm. It has strong adaptability to rock drilling conditions and is almost independent of rock drill type and rock mass performance. Cross- and ball-toothed bits are commonly used in mining projects in many countries, such as Sweden and Canada. On the basis of comprehensive experience of foreign absorbing technology, our company has adopted a new design in terms of geometric structure, parameters, materials, manufacturing process and use technology based on the current situation of China's material and brazing technology. , reaching the highest level in China.
