A tooling utility system especially well suited for punches and dies employed in pharmaceutical tableting procedures is described. Punch trays, nesting one on top of another, have support rails with oppositely positioned arcuate cut-outs which provide nesting segments for securing the punches during transport and storage. Dies, placed within a cavity including a die support, are similarly secured in position. A substantial portion of the surface area of the punches and dies remain fully exposed, making for simplified inspection and cleaning procedures, including placing the vertically nesting trays directly into a sonic cleaner. The trays themselves form the outer structure of the tool system, secured together by hinged side covers or front and back snap on side covers. A unique tongue and groove interlocking arrangement is described which is disposed upon the top and bottom surfaces of the trays. The tongue and groove arrangement allows for the trays to be orientated in either one of two positions; and when empty, to permit placement on either side upon a lower tray in the stacking. The described system allows for a varied number of trays to be used to handle different size sets of tooling.
