The drill bit has the functions of impacting, crushing and shearing to break the formation rock while rotating. Therefore, the drill bit can adapt to soft, medium and hard formations, which greatly improves the drilling speed. A series of ABT well drilling bits types: DTH drill bits, hole opener drill bit, threader drill bit, anchor drill bit, core hole bits, cutting pick made of durable material for long-term use. The specifications are comprehensive for various application.
During the digging operation, the drill bit opener rotates around the vertical axis and simultaneously moves back and forth in the axial direction. The soil is cut under the action of the torque and axial force of the drill bit, and it is destroyed and broken up under the action of the squeezing and centrifugal force of the working blade, and the soil flow is pressed against the pit wall, and it is lifted along the page to the surface. When the soil flows to the place where there is no pit wall barrier, the crushed soil is thrown around the pit due to the centrifugal force, and the entire digging process is completed.
In mining and construction industry, well drilling bits are a type of boring tools that drill through and penetrate soft and hard rock materials. ABT supplies different drilling rig bit types which are widely used for mining, quarrying, tunneling, construction, well drilling, geological exploration, and blasting applications. We’ve optimized drill bit with less replacement time in open-cast coal mines and long service time.
