A multifarious boring device includes a work table and a head with a variety of machine tools or cutters. The work table and the head are controlled by a computer through a shifting device and a power device. The computer computes distances and directions between the cutters and working points on a workpiece on the work table. Thereby, the shifting means controlled by the computer shifts the work table having the worked material thereon. The power device controlled by the computer powers one of the cutters. Codes of the type of holes and working points are fed into the computer. Thereby, a desired hole can be made at a desired point on the workpiece, and different patterns can be made in different types of workpieces.
