DRILL WIRE SLEEVE

The present invention relates to a drill wire sleeve (100) consisting of a tubular, elongate sleeve (101) having a length L, an inside diameter di and an outside diameter da. The drill wire sleeve (100) has a first axial end cap (110) and a second axial end cap (111), wherein the first axial end cap (110) and/or the second axial end cap (111) is fastenable releasably to the tubular, elongate sleeve (101) in a tool-free manner by way of a thread (104, 105) and releasably closes an introduction opening (112) of the tubular, elongate sleeve (101). The first axial end cap (110) and/or the second axial end cap (111) has a non-rotationally symmetric external cross section and the tubular, elongate sleeve (101) has, in its lateral surface, a multiplicity of first apertures (106). The first apertures (106) are configured in an elongate manner and inclined at an angle of 25 degrees to 65 degrees to the longitudinal axis of the tubular, elongate sleeve (101), preferably at an angle of 28 degreesto 55 degrees and more p
