Abstract (en)
[origin: EP0344117A2] The production of grooves (1a) on the insertion end (1) of a drilling and chiselling tool is effected by means of segments (2) rolling on the insertion end (1) in the axial direction. The segments (2) are arranged on levers (3) which are mounted in such a way as to be rotatable about a pivot (4) essentially perpendicular to the axial direction of the insertion end (1). The levers (3) are driven by a working cylinder (8) and actuated in synchronism with one another, with the result that a plurality of grooves (1a) are rolled into the insertion end (1) simultaneously. <IMAGE>
