Abstract

Procedure and device for drilling with hollow and/or solid bits, especially deep holes, with several blades arranged in a circle, one behind the other, and partially superimposed, characterized in that with a blade a cutting surface is formed which, in the projection of the direction of drilling, is in the middle part of the cutting surface produced by the other blade and in the direction of drilling, deeper than the cutting surface recently mentioned located in a shallower area.
