The invention discloses drilling equipment capable of automatically controlling the drilling depth. A detection unit tests the inlet depth of a drill bit and automatically feeds the depth back to a numerical control unit. When the numerical control unit determines that the actual depth of the drill bit reaches a first preset position, the drill bit is notified of reducing the rotating speed of the drill bit to ensure that the drilling position is not shifted. When the numerical control unit determines that the actual depth of the drill bit reaches a second preset position, the rotating speed of the drill bit is increased and returned to a normal state.
