ABSTRACT:
A tool guide for providing controlled support for a portable power tool such as an electric drill. When the lower portion of the device is clamped between the vise jaws of a portable workbench and vise, an electric drill slidably mounted on the device may be used to drill either perpendicular or angular holes in a workpiece positioned on top of the vise jaws. The device may also be used independently to add accuracy to free hand drilling for both perpendicular and angular holes.
