ABSTRACT:
A gang tool assembly for drilling a precise pattern of holes in a workpiece or otherwise cutting surfaces and the like on such workpiece and including a mounting panel of rigid sheet material having a pattern of holes formed therein to receive supports for powered tool heads to detachably support the same to form a gang pattern of either drills or cutters for simultaneously drilling a pattern of holes in a workpiece or forming a contoured surface thereon. The mounting panel is formed by at least pricking with pins a pattern of holes upon a sheet-like pattern of all holes to be drilled and forming partial patterns of the entire pattern separately upon said sheet-like pattern and digitizing the same upon a tape for use in a numerically controlled machine operable to successively drill a series of rigid sheet-like support plates for holding powered drill heads in partial patterns of said entire pattern and comprising a set thereof for use to drill patterns of holes in sets of test and base plates respectively requiring holes of different diameters for use in ultimately drilling holes in product sheet material having the entire required pattern of holes therein.
