In geological exploration, the drill bit generates vibration under the actions of axial pressure and rotary torque, normal stress, tangential stress and displacement, which have negative influences on drilling. If resonance is formed, it will bring destructive effect and obstruction on the drilling tools and drilling process. Using bit matrix material with high vibration damping capacity is one of the effective methods to reduce the bit vibration. Scientists of Tula Scientific Research Institute of Geological Exploration in Russia have studied the vibration damping capacity of different materials and considered that the vibration damping capacity of material BK6M with linear dimension 0.04mm is better than the other materials that have been tested. In Ural region, production test was carried out by geological exploration team ГП-УС-30 on the bit made of WC powder with linear dimension ratio 1.15～1.25 and area ratio 40∶1～48∶1 and large-particle Relit hard alloy powder, good technical and economical results are obtained, bit service life increased by 50% and specific expense of diamond reduced by 80%～90%.
