A tool for countersinking nails into a workpiece has a base member, which is formed of resilient material, and has a generally flat bottom section resting on the workpiece. A metal guide is mounted in the base member. The guide has a central opening for receiving a nail in its bottom. A rigid cap member on the base above the guide has an aperture through it, and a nail set extends partially upward out of the aperture in the cap and extends into the opening in the guide above the nail for transmitting impact from a hammer on the nail. The bottom of the guide member is recessed from the bottom surface of the base so that the metal will not contact the workpiece. The cap has a greater diameter than the guide so that if the cap is struck when the bottom or the nail set is below the top of the workpiece, an impact on the cap is not transmitted to the guide but will be absorbed in the resilient material of the base. A nail starting section integral with the base member extends laterally outward. It contains starting holes that grip nails initially. A slot extends from each opening to a larger opening, and the tool can be pulled over a nail until the nail is in the larger opening where it can be removed from the nail. |
