Abstract

The invention relates to a drilling method that comprises: the step of drilling a hole in the ground, during which a drilling pipe (102), provided at one end thereof with a cutting tool (106) removable from said pipe, is rotated, the cutting tool generating vibrations, followed by: the step of disengaging the cutting tool, during which an object is moved axially in the drilling pipe in the direction of the end in order to urge the cutting tool out of the drilling pipe.
