ABSTRACT:
An apparatus for increasing hand drill pressure includes a lever having a first end and a second end. A sleeve is affixed transversely to the lever spaced from the first end. An anchor line is provided having a first end and a second end. The first end of the anchor line is secured to the first end of the lever. A hook is provided on the second end of the anchor line. The sleeve slides over a handle of a hand drill. The hook is used to anchor the anchor line to a workpiece. The lever provides a mechanical advantage to increase the pressure with which the hand drill engages the workpiece.
