The drilling jig comprises two sleeves of identical design mounted alongside each other on a common holder, with each sleeve being mounted on the holder so as to be pivotable in relation to each other about an axis of rotation extending perpendicular to their respective longitudinal axes. Each sleeve is hollow to allow a drilling tool to pass through. At the rear end of each sleeve is a stop surface for the drilling tool to rest against, the stop surface delimiting the depth to which the drilling tool penetrates the sleeve. Each sleeve is of two-part design and includes a bearing part and an adjusting part, with the bearing part carrying the front end of the sleeve and the adjusting part carrying the stop surface. The bearing part and the adjusting part are threaded to each other in such a manner that the spacing between the stop surface and the front end of the sleeve is adjustable by turning the adjusting part in relation to the bearing part, which enables alteration of the effective length of the sleeve without removing the drilling tool.
At the rear end, the shaft section 16 continues into a disk-shaped grip part 19, the circumferential surface of which is provided with a profile, for example, knurling 20. The grip part 19 is flattened on one side, with the flattened part 21 extending over, for example, an angle of almost 90
The operator then sets the desired drilling depth individually for each hole to be drilled by turning the adjusting part 7 in relation to the bearing part 6. The spacing of the grip part 19 from the tips 9 is thereby adjusted. By feeling the flattened part 21, the operator can sense the number of rotations of the adjusting part 7. The fixing of the adjusting part 7 by the detent body 25 while it is being turned in the bearing part 6 is also an orientation aid to him as renewed fixing always occurs after a rotation through 180
