    • The invention relates to a reaming tool for reaming out several axially interspaced borings (14) of a workpiece (12). The reaming tool comprises a guide shank (16) which can be clamped into a machine spindle and which can be supported in prepared borings (14) of the workpiece (12) to be machined using external supporting elements (18). The reaming tool also comprises a reaming head (26) which coaxially connects on the front end thereof. In order to be able to easily change a worn tool, the invention provides that the reaming head (26) can be connected to the guide shank (16) by means of an auto-centering clamping mechanism (30), and that the supporting elements (18) positioned in the proximity of the clamping mechanism (30) can, during a clamping process, be radially spread in an at least partial manner from a dimension smaller than that of the diameter to a predetermined diameter guide dimension.
    • 本发明涉及一种用于铰孔的多个工件(12)的间隔开的轴向间隔开的孔(14)的扩孔工具。 扩孔工具包括由外侧支承元件(18)支承的导向轴(16),并且在随后的铰削头(26)的其端面端同轴的方式在机器主轴上的可夹紧的,在工件的准备的孔(14)被加工(12)。 为了使在Verschleissfalle一个简单的工具的变化,它是按照本发明所提出的是,铰削头(26)通过一个自定心夹持机构(30)与所述引导轴(16)的装置是可连接的,并且定位在支撑元件的夹紧机构(30)的附近( 18)被径向地夹紧操作过程中从一个直径筛至预定直径尺寸导向膨胀至少部分。
