Abstract

The drilling rod, for assembly into an elongated system of rods has a connecting portion on at least one end, for axially joining it to the next rod. Tension-reducing deformations (14) are incorporated along the rod (10) extending over at least the major portion of the length of the connectors. The rod is pref. tubular, with the connectors (12) monolithically formed on it extending along its inside periphery. The deformations can be monolithically formed with the rod and located on its outside periphery. The connectors pref. comprise pitched threads (16) while the deformations comprise axially spaced peripheral grooves (22).(1/8)
