Abstract

A twist drill or drill/chamfer tool that comprises a drill with a shaft section. The shaft section is provided with a twisted flute and a clamping ring as the retainer of a facing cutter. The clamping ring tubularly encloses the shaft section or the drill shaft and can be fixed on the shaft section or drill shaft in different axial adjustable positions. The clamping ring can be tensioned on the drill with tension screws that extend through the clamping ring substantially radially to the axis of the drill. The tension screws impinge the surfaces of the twisted flutes, which twisted flutes are enclosed by the clamping ring indirectly with a clamping shoe that is interposed in a twisted flute.
