摘要： The lathe tool, in particular the boring tool (2) has a receiving part implemented as a borer body (6) and a front part implemented as a borer head (4), which extend along a central axis (8) and can be removably fastened to one another via a driver connection. The driver connection comprises at least two coupling pairs which are separate from one another and are disposed eccentrically relative to the central axis (8). Each coupling pair is formed by interlocking coupling elements, namely a receiving pocket (20) and a driver pin (18). The coupling elements are implemented such that upon joining of the borer head (4) and the borer body (6), they are centered to one another and oriented aligned via the coupling elements. The coupling elements (18, 20) have an asymmetrical cross-sectional area for this purpose and widen with increasing distance to the central axis (8) for good torque transmission. Through said design, a reliable transmission of even high torques is achieved in comparison to the solution known from the prior art with lower strains of the borer body (6) in the area of the driver connection. Simultaneously, an automatic centering of the two tool parts to one another is performed by the special design.

摘要： The invention relates to a rotary tool (2) designed in particular as a modular drill and extending in an axial direction (4) along an axis of rotation (6). The rotary tool comprises two coupling parts, namely a carrier (10) and a cutting head (12) that is exchangeably attached to the carrier (10). A pin receiving means (20) is provided on the carrier (10), into which pin receiving means a coupling pin (40) of the cutting head (12) is introduced in a clamping and reversible exchangeable manner. The pin receiving means (20) and the coupling pin (40) have clamping sections (32a, b) and torque sections (30a, b) that correspond to one another. In order to permit simple production, these clamping and torque sections are oriented parallel to the axis of rotation (6). In addition, in order to prevent pulling-out in an axial direction, stop surfaces (38a, b) are provided on the pin receiving means (20) and on the coupling pin (40), said stop surfaces being effective in an axial direction (4) and corresponding to one another. These stop surfaces are preferably horizontal and therefore perpendicular to the axis of rotation (6).
摘要翻译：旋转工具（2）特别地被设计为模块式钻机，并且沿着旋转轴线（6）在轴向方向（4）上延伸。它包括两个联接部分，即载体（10）和连接到载体（10）以便可更换的切割头（12）。一个销接收装置（20）设置在所述托架（10）上，所述销接收装置以所述夹紧方式引入所述切割头（12）的联接销（40），以便可逆地更换。销接收装置（20）和联接销（40）具有彼此对应的扭矩部分（30a，b）和夹紧部分（32a，b）。为了允许简单的生产，这些夹紧和扭矩部分平行于旋转轴线（6）定向。此外，为了防止轴向拔出，在销接收装置（20）和连接销（40）上设置止动面（38a，b），所述止动面在轴向上有效（4）并相互对应。这些止动表面优选地水平延伸，因此垂直于旋转轴线（6）。
