Said bores correspond with opposite bores in a drill guide block and are disposed in accordance with the pattern of the holes to be drilled. A coupling arrangement is provided in the space between the drill guide block and the spindle guide block for connecting the shanks of drill bits placed in the bores of the drill guide block to the spindles.
