Bellino - Augers

They have both the tool-joints welded (friction welded) on the pipe and also for this they guarantee more reliability and quality.

The pipe, made of N80 steel, ensures a tensile strength of 680Nmm2, and the metal spiral has a thickness of 10mm and – with the cutting edge process available in house - it is welded on a drill rod in order to obtain a continuous flighting.

The augers’ pitch is designed depending on the outside diameter, so that the feeding speed can guarantee the holes’ uprightness.
