    • The tool and the toolholder have two sections (18, 19, 20, 21) with different cross-section sizes arranged one after the other. Said sections (18, 19, 20, 21) in the tool shaft (3) and in the toolholder (1, 2) form reciprocal supporting faces. The first section (18) in the tool shaft (3) and the first section (20) of the toolholder (1, 2) have rotating and locking means (5, 11, 12, 13, 14, 15, 16) interacting with one another. The invention aims at providing a tool and toolholder that are compact and have a low rate of ware. To this end, the rotating and locking means (5, 11, 12, 13, 14, 15, 16) are arranged in parallel in axial direction of the shaft (3) or the toolholder (1) and serially relative to one another in peripheral direction. Furthermore, the distance between the rotating and locking means (5, 11, 12, 13, 14, 15, 16) arranged in the first section (18, 20) of the shaft (3) or toolholder (1) and the cross-sectional spread from the first section (18, 20) to the second section (19, 21) which has a larger cross section is shorter than the area of the shaft (3) or toolholder (1, 2) that is fitted with the rotating or locking means (5, 11, 12, 13, 14, 15, 16).
    • 刀具和刀架各自具有两个轴向连续布置的具有不同横截面尺寸的部分(18,19,20,21)。 刀柄(3)和刀架(1,2)上的这些部分(18,19,20,21)形成相互的支承表面。 在工具柄(3)和所述工具保持器的所述第一部分(20)的第一部分(18)(1,2)具有Drehmitnahme-和锁定装置(5,11,12,13,14,15,16),其在相互 活性化合物支架。 它是一种工具和一个刀架,它们都非常紧凑和低磨损。 为此,柄部(3)的轴向方向上的Drehitnahme-和锁定装置(5,11,12,13,14,15,16)和工具保持器(1)沿着彼此平行且在圆周方向上彼此串联布置。 此外,在柄部(3)的第一部分(18,20)与刀具夹持器(1)之间存在的Drehitnahme-和锁定装置(5,11,12,13,14,15,16)之间的距离以及在 第一部分(18,20)到较大横截面具有第二部分(19,21)比所述一个与所述Drehmitnahme-和锁定装置(5,11,12,13,14,15,16)的柄部的搭载区域(3短 )或刀架(1,2)。
