Abstract:
A tooling accessory for use with a conventional hand drill having a modified body comprising:a substantially flat base place having a central opening; a vertical member arising out of and perpendicular to the perimeter of the base plate, the vertical member having a curved cross-section sized to slidably engage corresponding curved slots in the modified body of the hand drill; and, the vertical member having a stop located a variable distance from the base plate and having markings indicative of said distance, the stop preventing further movement of the hand drill towards the base plate; whereby the hand drill may engage the vertical member and the base plate may contact a surface to be drilled, and the hand drill slidably moved towards the base plate until the stop is reached, facilitating drilling of a perpendicular hole of a controlled depth.
