ABSTRACT:
A tool guide for providing a stationary 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. An adjustable depth stop operatively associated with the slideway of the device provides accurate depth control. The device may also be used independently in order to add accuracy to free hand drilling for both perpendicular and angular holes.
