A feature of the countersinking tool according to the invention, which is very important in relation to the service life of the countersink, results from the fact that the conical FUIirun ^ sbolsen in its part facing the countersink is a cross section right = eeki ^ en 'off $ the diameter of which is greater than the inner diameter of the locking hole. Uaah · this feature , the distance between the opposite cutting point is less than the width of the attachment 9 so that the point of application for the Ssiineidlsruppen is shifted from the Scliaeidspitaen v / eg near the outside, to di @ s € ^; .
