摘要： A rotatable tool for chip removing machining includes two parts, viz. a holder part, rotatable around a geometrical center axis, and a replaceable cutting part, which is rigidly connectable to a front end of the holder part via a male/female coupling. The coupling includes a tapering seat in the holder part and a tapering male member, protruding rearwardly from the cutting part. In the seat, there is a slot, which separates two elastically deflectable projections, that may be inwardly deflected towards each other during clamping of the male member in the seat. The male member is elongated in a radial direction, and the seat is in the form of a radial groove into and out of which the sheath body is transversely movable. The male member includes a dove-tail shaped portion received in a dove-tail shaper portion of the groove. A centering button on the male member enters a depression in the holder part to axially center the cutting part.

摘要翻译： 用于切屑去除加工的可旋转刀具包括两部分，即 可绕几何中心轴线旋转的保持器部件和可更换的切割部件，其经由公/母联接器刚性地连接到保持器部件的前端。 联接器包括在保持器部分中的锥形座和从切割部向后突出的锥形凸形构件。 在座椅中，有一个狭槽，它分开两个可弹性偏转的突起，这两个弹性偏转突起可以在将阳构件夹紧在座中时朝向彼此向内偏转。 阳构件在径向方向上是细长的，并且座体是径向凹槽的形式，鞘主体是可横向移动的。 阳构件包括容纳在凹槽的尾部成形器部分中的鸠尾形部分。 阳构件上的定心按钮进入保持器部分中的凹部以使切割部件轴向居中。
