Abstract

1. Drilling device for producing drilled holes (14) with an undercut (13), consisting of a drill bit with a drill tip (2) having a lateral cutting-edge (4) projecting radially beyond the drill shank (1), and of a drill bit holder (6) provided with a clamping shaft for an impact drilling machine and having a bulbous, radially projecting collar (9) provided with longitudinally extending slot openings, which collar, to form a swivel bearing, acts against a depression (10) of a stop plate (12) fitted over the drill shank (1) and having a sleeve-like centering extension (15) engaging in the drilled hole, characterized in that the stop plate (12) has axially extending members (17) adjoining the depression (10), which members are angled inwards behind the collar (9) of the drill bit holder (6).
