    • 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).
    • 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)。

    • A rotary cutting tool (10) includes a generally cylindrical body having a first end (12), a second end (14) and a longitudinal axis therebetween (16). A mounting portion (18) is disposed about the first end (12), a head portion (20) having an outer diameter (D) is disposed about the second end (14), and a body relief portion (22) having an outer diameter (d) less than the head portion (20) is disposed therebetween. The head portion (20) is structured to engage and cut a workpiece. A number of flutes (24) extend from the second end (14) of the cylindrical body along the head portion (20) and along at least a portion of the body relief portion (22). The head portion (20) includes a number of margin relief surfaces (30), each disposed between adjacent flutes (24) and inset a distance (t) from the outer diameter (D) of the head portion (20) and extending from the second end (14) of the cylindrical body and terminating at a margin seal (32) within the head portion (20).
