Our advantage of making tungsten carbide button bits is that we are using HIP sintering for minimizing the porosity of carbide blank for increasing the transverse ruputure strenth (TRS). It is very suitable for high quality requirment for making carbide bottons to be ued in high and medium pressure DTH Drilling. As its unique working performance, tungsten carbide button bits are widely applied to oil filed drilling and snow removal, snow plough machines or equipments.
