Abstract:
1. A positive-feed drill motor assembly comprising: a positive-feed motor comprising a spindle which rotates around a spindle axis and simultaneously translates in a direction parallel to the spindle axis; a gearbox comprising a plurality of gears rotated by the spindle, said plurality of gears configured to engage and rotate a drill-bit around a drill-bit axis which is offset from the spindle axis; and a clamp comprising a pilot-hole finder, and an upper clamp arm and a lower clamp arm which move relative to one another, wherein when the pilot-hole finder is disposed in a first position the pilot-hole finder starts the positive-feed motor or begins clamping with the clamp and when the pilot-hole finder is disposed in a second position the pilot-hole finder turns off the positive-feed motor or retracts the clamp; wherein the gearbox and a drill-bit attached thereto are configured to simultaneously translate with the spindle in the direction parallel to the spindle axis as the spindle rotates around the spindle axis.
