    • Cutting tool (100) for forming a final opening in a stack (230) that includes at least two layers and a pilot opening (240) having a pilot-opening dimension and extending through at least one of the at least two layers. The cutting tool (100) includes a shank (120). The cutting tool (100) also includes a first portion (112) including at least one of a first coating (116) or the first coating (116) and a second coating (118), wherein the first coating (116) at least partially covers the first portion (112). The cutting tool (100) also includes a second portion (114) between the shank (120) and the first portion (112), wherein the second portion (114) includes the second coating (118), and wherein the second coating (118) at least partially covers the second portion (114). Also a method of processing a stack providing such a cutting tool.
    • 用于在包括至少两个层的堆叠(230)中形成最终开口的切割工具(100)和具有先导开口尺寸并延伸穿过所述至少两个层中的至少一个层的先导开口(240)。 切割工具(100)包括柄(120)。 切割工具(100)还包括包括第一涂层(116)或第一涂层(116)和第二涂层(118)中的至少一个的第一部分(112)和第二涂层(118),其中第一涂层(116)至少部分 覆盖第一部分(112)。 切割工具(100)还包括在柄(120)和第一部分(112)之间的第二部分(114),其中第二部分(114)包括第二涂层(118),并且其中第二涂层 )至少部分地覆盖第二部分(114)。 还提供了一种处理提供这种切割工具的堆叠的方法。

    • A cutting tool (110) for forming a hole by means of orbital drilling is provided. The cutting tool includes a body (112) having a first portion (118), which has a first diameter and a first radial rake angle (124: Fig. 2), and a second portion (120) adjacent the first portion (118), the second portion (120) having a second diameter and a second radial rake angle (126: Fig. 3). The second diameter is different from the first diameter and the second radial rake angle (128) is different from than the first radial rake angle (124). In preferred embodiments the second diameter is larger than the first diameter and the first radial rake angle (124) is positive, whilst the second radial rake angle (128) is negative, such that residual stresses may be imparted to the wall of the orbitally drilled hole. A system (110: Fig. 7) for, and a method (300: Fig. 9) of, orbitally drilling a hole are also provided, wherein the system includes the cutting tool (110).
    • 提供了一种用于通过轨道钻孔形成孔的切削工具(110)。 该切削工具包括具有第一部分(118)和第二部分(120)的主体(112),该第一部分具有第一直径和第一径向前角(124:图2) ,第二部分(120)具有第二直径和第二径向前角(126:图3)。 第二直径不同于第一直径并且第二径向前角(128)不同于第一径向前角(124)。 在优选实施例中,第二直径大于第一直径并且第一径向前角(124)为正,而第二径向前角(128)为负,使得可以将残余应力施加至轨道钻出的壁 孔。 还提供了用于轨道钻孔的系统(110:图7)和方法(300:图9),其中该系统包括切割工具(110)。
