ABSTRACT:
A drill press includes an overhead mount for supporting a power-operated drilling unit from an existing structure at locations above a work area, thereby enabling the accurate drilling of holes in large workpieces. An upright member is attached to one portion of the existing structure, such as a ceiling, and provides vertical support for a power-operated drilling unit. The upright member is extensible, enabling the drilling unit to be raised or lowered to accommodate workpieces of various sizes. Lateral support for the upright member is provided by brace members which connect the upright member to spaced portions of the existing structure.
