ABSTRACT:
A drill press and stand providing an improved apparatus for cutting holes in plate vitreous material. The drill press includes a drill motor, a drill tool attached to the drill motor for cutting through the work piece, and a motor support interconnecting to and supporting the drill motor on the stand. The stand includes a base which is attachable to the work surface by a large suction cup which is attached to the lower surface of the stand base. The stand also includes a collar integral to and generally perpendicular to the upper surface of the base into which a mating drill press standard, a part of the motor support may be inserted. The motor support also includes a positioning mechanism for longitudinally moving the drill motor along the standard and may include a biasing spring to counteract the weight of the motor, etc. The standard, along with the attached drill motor, may be pivoted about its longitudinal axis within the mating collar to allow drilling two holes at fixed distances apart through the work surface without repositioning the stand. The base includes a cutting coolant reservoir drill tool access hole which traps coolant inserted therein atop the work surface and around the hole cutting tool. A resilient coolant retaining ring fixed to the lower surface of the base just outside the perimeter of the tool access hole presses against the work surface as the stand is attached to the work surface, forming a liquid seal for the reservoir.
