Beschreibung
Zusammenfassung:	The invention relates to a drilling tool (10) which extends along a longitudinal axis (12) and comprises a drill bit (24), a connection section (20) for connecting the drilling tool to a suction adapter (400), a shaft section (22) between the drill bit and the connection section, and at least one conduit (44) that extends along the shaft section and is located radially between a sleeve element (42) and a shaft element (40). According to the invention, the sleeve element is integrally bonded to and/or interlocked with the shaft element in the shaft section. 本发明涉及一种钻具(10)，该钻具沿着纵向轴线(12)延伸，该钻具包括钻具头(24)、用于连接钻具和吸除适配器(400)的附接区域(20)、布置在钻具头和附接区域之间的杆部区域(22)和沿着杆部区域延伸的至少一个运输通道(44)，其中，运输通道在径向上布置在套筒元件(42)和杆部元件(40)之间。提出了，套筒元件在杆部区域中材料锁合和/或力锁合地与杆部元件连接。
