Abstract (en)

[origin: EP0378964A2] The trepanning tool, consisting of a support part (1) and a cutting body (2), has guide segments (3d) following the cutting body (2) towards the support part (1) in the opposite direction to the feed direction. The outer contour of the segments (3d) essentially corresponds to the outer contour of the cutting body (2). The segments (3d) serve to guide the trepanning tool in the bore produced by the cutting body (2). <IMAGE>
