Abstract

The tool joint 1 for drill pipe used for boring oil or gas well. The pin 3 is provided with an outside shoulder 35, a pin base 34 having an outer periphery surface parallel with the pipe axis 50, a male threaded part 33 having a predetermined taper to the pipe axis 50, and a pin nose 32 having an outer periphery surface parallel with the pipe axis 50. The box 2 is provided with a box access sleeve 22 having an inner periphery surface parallel with the pipe axis 50, a female threaded part 23 engaging by thread with the male threaded part 33, a box end sleeve 24 having an inner periphery surface corresponding to the outer periphery surface of the pin nose 32, and an inside shoulder 25. By increasing a total of a mating surface between the outside shoulder 35 and a box access sleeve end portion 21 and a mating surface between the inside shoulder 25 and a pin nose end portion 31, higher torque characteristics is realized without reducing the operativity.
