The invention relates to a screw drilling rod. According to the screw drilling rod, a connection sleeve is arranged at the left end of a rod body; an inner connection rod is arranged at the right end of the rod body; screw blades are arranged on both of the rod body and the connection sleeve; a spring pin insertion hole and a U-shaped pin insertion hole are formed in the connection sleeve respectively; a spring pin is arranged on the inner connection rod, and pin grooves are symmetrically formed in the inner connection rod; the adjacent inner connection rods are embedded in the connection sleeve; the spring pin is inserted in the spring pin insertion hole; and the two ends of a U-shaped pin are sequentially inserted in the U-shaped pin insertion hole and the pin grooves respectively. The invention further relates to a production method for the screw drilling rod. The production method comprises the following steps: blanking round steel and the rod body; carrying out squaring treatment on the rod body; levelling the end surface of the rod body; carrying out cylindrical turning on the round steel; carrying out square milling, drilling and groove milling; rounding the inner connection rods; carrying out press-fitting on the connection sleeve, the inner connection rods and the rod body, and the like. The screw drilling rod and the production method thereof, which are disclosed by the invention, have the following beneficial effects: the screw drilling rod is high in structural strength, convenient to connect and higher in stability; and high machining accuracy and high working efficiency are achieved due to automatic machining.
