The utility model provides a radio frequency testing head capable of prolonging the service life of the inner wall of a needle tube, and relates to the field of radio frequency testing. The radio frequency testing head capable of prolonging the service life of the inner wall of the needle tube comprises an insulator, a flange is arranged at the upper end of the insulator, and the needle tube is installed in the insulator. According to the radio frequency testing head capable of prolonging the service life of the inner wall of the needle tube provided by the utility model, the side groove with a certain length is additionally arranged on the wall of the needle tube, so that the flow pattern of cleaning liquid on the inner wall of the needle tube is increased, the residue of metal chips in the needle tube is reduced, the roughness of the inner wall of the needle tube is improved, and the yield of the needle tube is also improved; by improving the roughness and consistency of the inner wall of the needle tube, t
