Abstract

Ein Drehschlag-Wendelbohrer besitzt einen Bohrerschaft (1), der mit wenigstens einer, spiralförmig entlang seiner Längserstreckung verlaufenden Hauptabfuhmut (4, 5) für Bohrmehl ausgestattet ist. Am Schaftende (10) sind eine Schneidplatte (6) und Zusatzschneiden (11) vorgesehen, die im wesentlichen X-förmig zueinander in der Stimfläche (3) am Ende des Bohrerschaftes (1) angeordnet und fixiert sind und die Stimfläche (3) des Schaftes (1) axial und den Mantel (2) radial überragen. Die Zusatzschneiden (11) überragen die peripheren Bereiche der Schneidplatte (6) axial und/oder radial. Bezogen auf die Drehrichtung (R) des Drehschlag-Wendelbohrers ist der Winkel zwischen den Zusatzschneiden (11) und der nachfolgenden Schneidplatte (6) kleiner ist als 90°. Jeder Zusatzschneide (11) ist eine Hauptabfuhmut (4, 5) vorgelagert.
