    • In drilling a bore in a structural component (3) using a hollow cylindrical core drill bit (4) initially a guide such as a disk (1) or a template (12) is secured to the surface of a structural component (3) for guiding one of the inner or outer circumferential periphery of the core drill bit. At the commencement of the drilling operation, the core drill bit (4) is guided by the disk or template and maintains the bit in a centered position. The guide can be fixed to the surface of the structural component (3) in a known manner, such as by an adhesive or by fastening elements (2, 6) driven directly into the structural component. Generally core drill bits of smaller diameter can be guided by the outer circumferential periphery of the guide (2) or by the inside circumferential periphery of the template (12).
    • 在最初使用中空圆柱形钻头钻头(4)钻出结构部件(3)中的孔时,诸如盘(1)或模板(12)的引导件固定到结构部件(3)的表面上,用于 引导芯钻头的内圆周或外周边之一。 在钻孔操作开始时,芯钻头(4)由盘或模板引导并将钻头保持在居中位置。 引导件可以以已知的方式例如通过粘合剂或直接驱动到结构部件中的紧固元件(2,6)固定到结构部件(3)的表面上。 通常,较小直径的芯钻头可以由引导件(2)的外圆周或模板(12)的内圆周引导。
