ABSTRACT:
A reusable break-out support tool and method are provided for use in drilling, or the like, a workpiece. The tool employs a granulated media situated within a cylinder. When a workpiece is to be drilled, the cylinder with the granulated media is engaged with the side of the workpiece which will bear the exit opening of the hole to be drilled. The granulated media is pressurized whereby it forms a load bearing surface applied to the workpiece.
