A dowel-pin drill jig (10) consists of an angle (12) with two legs (16, 18). Located in the latter is a drill bush (22) and in the former a transversely orientated slot (20) as well as a threaded bolt (30) on either side of this slot (20). These threaded bolts (30) are screwed in so far that the axis of the drill bush (22) reaches the centre of width of the end face of the board (B1). In this position of the threaded bolts (30), a second board can be drilled at the edge on the flat side, in the course of which the correct edge spacing is automatically maintained. <IMAGE>
