The Secoroc Duralloy™ bit sub adaptors are used when adapting from one thread to another (drill pipe to drill bit); when coupling drill pipes having the same connections on both ends; or as thread savers.
Team rotary subs are manufactured from various application-specific, premium quality alloy steels.

To connect the Tricone drill bit to the drill pipe, in primarily softer rock formations that are dipped or result in sloughing the Secoroc EZ-Drill™ roller stabilizer is the ideal solution.
