    • A platelike drilling bit (1) may be secured by interlocking or friction engagement in the shank (2) of a self-drilling fastener. At its end region towards its shank (2), the bit (1) has a flat extension (4) in the plane of the bit (1). The end of the shank (2) carrying the bit (1) has a central aperture (5). The extension (4) of the bit (1) can be inserted in the aperture (5) in the shank (2) and supported in the aperture on two diametrically opposed limits to the inner wall of the aperture (5) providing a tight fit. This gives adequate support and the precisely axially parallel alignment of the bit (1) and the shank (2) without any additional machining.
    • 板状钻头(1)可以通过互锁或摩擦接合固定在自钻螺丝紧固件的柄部(2)中。 在其端部区域朝向柄(2),钻头(1)在钻头(1)的平面中具有平坦的延伸部(4)。 携带钻头(1)的柄(2)的端部具有中心孔(5)。 钻头(1)的延伸部分(4)可插入柄部(2)中的孔(5)中,并且在孔径(5)的内壁两个直径相对的极限上支撑在孔中,从而提供紧密配合 。 这提供了足够的支撑和钻头(1)和柄(2)的精确轴向平行对准,而没有任何额外的加工。
