Working Principle
The drill is equipped with impacter and drill head. In the working process, the piston of the impacter constantly impacters the tail of the drill head, and the alloy teeth of the drill head constantly impacter the rock. The gear reducer produces rotating torque, so that the drill tool rotates, and the axial force generated by the propeller cylinder is sent into the drill tool for drilling.
