  • Patent number: 4279551
    Abstract: A catch is pinned or screwed to a conventional hole saw pilot pin. The catch is free to pivot through an axial cutout in the pilot pin. The catch is sized and oriented to pass through a previously drilled standard sized pilot hole and is then pivotable out of the cutout into a projecting position extending radially of the pilot hole. In this position, a cut plug is retained on the pilot pin rather than dropped. Upon completion of sawing, the catch can be manually positioned back into the pilot pin cutout and the cut plug can then be removed.
