    • A chuck for rotary tools with a cylindrical chucking shank encloses such shank with a basic body. A radial through-hole in basic body serves to receive a clamping screw which applies pressure to a clamping member which is seated inside a through-hole between the clamping screw and chucking shank. A clamping member is provided with a radial projection and the through-hole with a cross-sectional narrowing along its inner end. In between the radial projection and the narrowing is an elastically compressible spring element which, due to its return force, lifts the clamping element away from the chucking shank and pushes it back into the through-hole when it is not under tension from the clamping screw.
    • 用于具有圆柱形夹持柄的旋转工具的卡盘将这样的柄部与基体相结合。 基体中的径向通孔用于接收夹紧螺钉,该夹紧螺钉对夹紧构件施加压力,夹紧构件位于夹紧螺钉和夹紧柄之间的通孔内。 夹紧构件设置有径向突出部和通孔,其横截面沿其内端变窄。 在径向突起和变窄之间是可弹性压缩的弹簧元件,其弹性可弹性元件由于其返回力而提升夹紧元件远离夹紧柄,并且当其不受夹紧螺钉的张力时将其推回到通孔中 。

    • A milling cutter is provided with a base body that can be driven in a rotating manner around its longitudinal axis. Support bodies are distributed over the surface of the base body and are supported from centrifugal forces by a base body stopper and are positioned in tension against the base body stopper. The base body has an end face with a central area and a peripheral area around the central area, which central area is recessed with respect to the peripheral area. The central area and peripheral area together forming a step which acts as the base body stopper. The support bodies comprise a counter-step which can interlock with the base body, and a mounting plate is positioned at the end face to support the support bodies.

    • A twist drill has a cutting member at the bottom, a shaft at the top, and a reduced-diameter root clearance region between the cutting member and the shaft. Cutting edges are provided at the transition between the cutting member and the root clearance region, and further cutting edges are provided at the transition between the shaft and the root clearance region. After a throughhole has been drilled using the cutting member, the drill is displaced laterally and moved along a circular path while it is still rotating. As a result, the cutting edges at the transition between the cutting member and the root clearance region countersink the bottom end of the throughhole. A similar procedure is employed to countersink the top end of the throughhole using the further cutting edges at the transition between the shaft and the root clearance region.
