Drill tubes are an integral part of the drill string, extending the holes depth, transferring rotation and delivering air to the hammer and connecting to the expensive items at the bottom of the hole.
As such, the quality, machining and finish of drill pipes is very important and false economy to settle for a cheaper, inferior product.
Bulroc drill tubes are produced from cold drawn seamless material to ensure a smooth concentric bore. The male and female threaded tool joints are machined from a high quality alloy steel, heat treated to produce a hard wear resistant surface then friction welded to give a strong, consistent weld for long life and dependability.
Bulroc drill tubes are fitted with thread protectors and finished with a protective surface coating.
