This recommended practice involves not only the selection of drill string members, but also the consideration of hole angle control, drilling ßuids, weight and rotary speed, and other operational procedures.


Sections 4, 5, 6, and 7 provide procedures for use in the selection of drill string members. Sections 8, 9, 10, 11, 12, and 15 are related to operating limitations which may reduce the normal capability of the drill string. Section 13 contains a classiÞcation system for used drill pipe and used tubing work strings, and identiÞcation and inspection procedures for other drill string members. Section 14 contains statements regarding welding on down hole tools. Section 16 contains a classi- Þcation system for rock bits.
