ABSTRACT:
This disclosure relates to a punching apparatus for perforating sheet metal or the like, comprising a tool holder having a body portion which includes upper and lower arms extending horizontally from the body portion in vertically spaced alignment from one another to form a throat into which sheet material to be punched may be positioned. Each of the upper and lower arms includes a plurality of spaced bores of different diameters, each of which is vertically aligned with a corresponding bore in the opposite arm. The bores in the upper arm are adapted to receive a plurality of punches of different diameters, while the lower bores are adapted to receive a plurality of dies of different diameters for operatively receiving a corresponding punch during a punching operation. The tool holder is slidably mounted in a work table disposed beneath a vertically movable ram of the apparatus, whereby corresponding ones of punches and dies may be selectively operatively positioned beneath the ram to punch holes of varying diameters.
