The ball tooth down-the-hole drilling tool is a down-the-hole drilling tool with ball teeth. It uses the special shape and hardness of the ball teeth to break rocks and soil to achieve the purpose of drilling. This kind of drilling tool usually consists of drill bit, down-the-hole impactor and drill pipe. During the drilling process, the down-the-hole impactor presses the ball teeth into the rock or soil through impact force, causing it to break. At the same time, the drill pipe carries the broken rock or soil out of the borehole. It has the advantages of high efficiency, low cost and reliability, and is widely used in geological exploration, mining, engineering geology and other fields.
