Down-the-hole drilling pipes
Sandvik offer a line of drill pipes which provides you with a great degree of compatibility between rigs and tools.
Cold-drawn seamless tubing material, N80, is used to ensure straightness, thickness and high strength enabling a smoother drilling process and a longer service life. The material also provides a smooth fine surface that eliminates the risk of hammer failures caused by scaling. Furthermore, the tools joints are made out of micro alloy steel and are case-hardened for superior thread life.
