Abstract
The invention is directed to a jig for boring doweling holes into alignment with one another in two boards or the like to be connected with one another by dowels or pegs and adhesives or bonding, comprising a plate which can be placed upon the board to be drilled, said plate comprising at least one guide hole for a drill and an adjustable and removable stop. In order to achieve elimination of the hitherto required insertion and removal of the dowels or pegs into or from the dowel holes of a board for positional determination of the bores in the second board, a displaceable or adjustable centering pin 14 probing the dowel hole 16 of the already drilled board 1 in an aligned manner is allocated to the guide hole 9.
