    Abstract: A novel magnification apparatus for power hand tools that allows working in confined workspaces is disclosed. In a first embodiment of the present invention, a magnification apparatus is attached to the top of the hand-held power tool using an adjustable friction mechanism that provides for an adjustment of the focus of the magnification apparatus. A tilt mechanism is also included that maintains the tool and workspace in the lens' field-of-view as the magnification apparatus is moved along the slot. This allows the operator to adjust the focus and magnification, thus allowing the clear viewing of the tools and workspace. In a second embodiment of the present invention, the magnification apparatus further includes a light for providing illumination in addition to magnification. The addition of the light in combination with the magnification apparatus increases the ability of the operator to view the tool and workspace, particularly in those cases where the workspace has poor ambient illumination.
