Mincon Rotacan offers Adaptors in a wide range of sizes, lengths, wrenching, and thread configurations to suit our customer’s needs. Adaptors are used in various positions within the drill string. A Bottom or Bit Sub Adaptor is used between the drill bit and drill pipe. Rotacan Bit Sub adaptors are easily recognizable with the industry unique Helical Hard Banding profile and provides extended protection for the working end of the drill pipe to which it is attached. Other Adaptors may be located elsewhere within the drill string to accommodate changes in thread to suit the applicable drill string components.
