description The invention discloses a drilling tool with a forcible entry function. The drilling tool comprises a power source, a drill rod, a positioning disc, a drill bit body and an impact rod body, the drill rod is installed at the output end of the power source, the positioning disc is installed at the tail of the drill rod, a positioning column is installed at the center of the lower surface of the positioning disc in a locking mode, a bearing assembly is installed at the bottom of the side wall of the periphery of the positioning column, and a positioning assembly is installed in the middle of the peripheral side wall of the positioning column. The drill bit body and the impact rod body can be quickly mounted and dismounted through the bearing assembly and the positioning assembly, subsequent quick dismounting is facilitated while stable operation of the drill bit body and the impact rod body is guaranteed, the overall machining range of equipment is enlarged, when forcible entry is needed, the impact rod body can
