Aicher Steel Americas Hollow Bar System


The Aicher Steel Americas hollow core bar system consists of three main components, the head, the steel tendon, and a single use drill bit. The steel tendon is a hollow core bar with continuous cold rolled threads throughout the bars 10' (3 m) length. The continuous threads are beneficial in the fact that they allow the bar to be cut at any desired length, or joined with our exclusive coupling system to achieve your desired drill depth. 

Designed to increase production, the Aicher Steel Americas hollow bar system can be simultaneously drilled and grouted into loose or collapsing soils without the need for a temporary casing. In order to insure smooth installation, Aicher Steel Americas sup­p­lies a lar­ge selec­tion of drill bits, al­lo­wing our cust­o­m­ers to in­stall the hol­low co­re bars in a va­rie­ty of dif­fe­rent soil con­di­ti­ons with most standard drill rig configurations. 

Due to the wide range of cross-sections and bar diameters available, we can design a system for you to carry almost any required load.
