Abstract: A drill wire sleeve includes a tubular oblong sleeve having a length, an internal diameter and an external diameter. The drill wire sleeve has a first axial end cap and a second axial end cap. The first axial end cap and/or the second axial end cap is detachably fastenable without tools on the tubular oblong sleeve using a thread and detachably closes an insertion opening of the tubular oblong sleeve. The first axial end cap and/or the second axial end cap has a non-rotationally symmetrical outer cross section and the tubular oblong sleeve has a plurality of first passages in its lateral surface. The first passages are formed oblong and are inclined at an angle of 25° to 65° in relation to the longitudinal axis of the tubular oblong sleeve, preferably at an angle of 28° to 55°, and more preferably at an angle of 31° to 52°.
