Abstract
864,606. Boring earth. AMERICAN IRON & MACHINE WORKS CO. Inc. Jan. 19, 1960 [Jan. 19, 1959; Dec. 21, 1959], No. 1944/60. Class 85. [Also in Group XXVIII] A drill pipe coupling having an end 10 adapted to be fixed to a drill pipe and threaded at 12 for connection with the pin of an adjacent coupling has rows of tungsten carbide inserts 20. The length d of each insert is greater than its width w. The outer end of an insert may be hemispherical, and protrude slightly above the periphery of the coupling.
