    • A trepanning drill having a drill axis of rotation (A) and comprising a drill bore extending rearwardly from a front portion thereof. The drill body has at least two cutting edges formed in the front portion thereof. Each of the cutting edges has a cutting external edge and a cutting internal edge. A circle passing through the cutting external edge of each of the cutting edges forms an external circle having a first diameter (D1) and a first center (A1). A circle passing through the cutting internal edge of each of the cutting edges forms an internal circle having a second diameter (D2) and a second center (A2). In an end view of the trepanning drill, the first center (A1) coincides with the drill axis of rotation (A), and, the second center (A2) is offset from the drill axis of rotation (A).
    • 一种具有钻头旋转轴线(A)并且包括从其前部向后延伸的钻孔的钻孔钻头。 钻体具有形成在其前部的至少两个切削刃。 每个切削刃具有切削外边缘和切削内边缘。 通过每个切削刃的切削外缘的圆形成具有第一直径(D1)和第一中心(A1)的外圆。 通过每个切削刃的切削内边缘的圆形成具有第二直径(D2)和第二中心(A2)的内圆。 在俯视钻机的端视图中,第一中心(A1)与钻头旋转轴线(A)重合,并且第二中心(A2)偏离钻头旋转轴线(A)。

    • A rotary cutting tool having a longitudinal axis defining forward and rearward directions and a direction of rotation, includes a cutting head releasably mounted to a front end of a tool shank. The cutting head includes a cap portion and a rearwardly extending tail portion. The cap portion is provided with a plurality of head segments, each head segment having a rotationally leading end facing the direction of rotation and a rotationally trailing end. The trailing end of each head segment is provided with a locking member which extends in a direction opposite the direction of rotation. The tool shank has a forward end provided with a corresponding plurality of locking recesses opening out to the direction of rotation, and a shank pocket recess. In the assembled tool, the tail portion of the cutting head is received into the shank pocket recess and each of the plurality of locking members is received into a corresponding locking recess.
    • 具有限定前后方向和旋转方向的纵向轴线的旋转切削工具包括可拆卸地安装到工具柄的前端的切割头。 切割头包括盖部分和向后延伸的尾部部分。 盖部设置有多个头部段,每个头部段具有面向旋转方向的旋转前端和旋转后端。 每个头部段的尾端设置有沿与旋转方向相反的方向延伸的锁定构件。 工具柄具有前端,前端设置有相对于向旋转方向开口的相应的多个锁定凹部和柄袋凹部。 在组装的工具中,切割头的尾部被接收到柄袋凹部中,并且多个锁定构件中的每一个被容纳到相应的锁定凹部中。
