Abstract

Die Erfindung betrifft einen Gesteinsbohrer mit einem Bohrerkopf, wobei am Bohrerkopf zumindest zwei Schneiden (3, 4) angeordnet sind, wobei die Schneiden von oben gesehen bezogen auf die Bohrerlängsachse im wesentlichen radial ausgerichtet sind, wobei die Schneiden jeweils eine vorzugsweise zusammenhängende Schneidkante aufweisen, die durch eine vorlaufend angeordnete Spanfläche (3b) und eine nachlaufend angeordnete Freifläche (4c) gebildet ist. Es wird vorgeschlagen, daß an mindestens einer Schneide die Freifläche mindestens eine im wesentlichen konvexe Ausformung (4d) - Freiflächenhügel - aufweist, die zusammen mit der Spanfläche eine im wesentlichen konvexe Ausformung in der Schneidkante - Schneidkantenhügel,- bildet.
