Abstract

Die Erfindung betrifft ein Schraubwerkzeug mit einem durch Formung und nachfolgendes Sintern eines Metallpulvers hergestellten, profilierten Vorderteil, das einen eine Stirnfläche aufweisenden Basisabschnitt (5) und einen Profilabschnitt (6) aufweist, der einen Eindringabschnitt und einen zwischen diesem und dem Basisabschnitt (5) angeordneten Übergangsabschnitt aufweist. Der Eindringabschnitt weist Stege (8) und zwischen diesen angeordnete Nuten (10) auf. Der Übergangsabschnitt wird durch radial auslaufende, die Stirnflächen des Basisabschnitts (5) bildende Flächenabschnite (16), erste, gewölbte Übergangsflächen (15), die die Nutenböden (11) in radialer Richtung mit Flächenabschnitten (16) verbinden, sowie zweite, ebenfalls gewölbte Übergangsflächen (17a, 17b) gebildet, die die Flächenabschnitte (16) in seitlicher Richtung mit den Stegflanken (8a) verbinden (Fig. 2).
