Self-Drilling Anchor

The KSB® (Küchler Self-Drilling Anchor) is a self-drilling anchor system with continuous external thread that can be drilled without casing in loose soil and rock whilst grouting at the same time.



Conventional threaded drill rods

The KSB® system is based on the conventional threaded drill rods R32, R38, R5, T176 and T114 up to loads of kN 1500 in tension and compression. A variety of compatible system components guarantee a wide range of applications such as tension, compression, slack, preloaded, permanent or as a jet system. The threads of the KSB® rods are cold rolled to the entire rod length. Through this vast cold forming not only is the steel tempered and the yield strength increased, but each rod is also subjected to mechanical material testing.

Easy injection

The continuous outer thread of the KSB® rod ensures safe cuttings promotion and the great inner diameter of the KSB® rod guarantees an easy injection, even for very long drill holes. If necessary, a centering of the micropile can take place with spacers after completion of the bore.
