ABSTRACT:
The present invention provides an automated-torque controlled tool for attachment to a milling machine. The tool comprises an elongated hollow housing defined by a neck section, a middle section, and a bottom section. The neck section is adapted to engage a spindle of the milling machine for rotational and axial movement therewith. A torque spring is situated within the middle section of the housing. A torque adjuster is dimensioned and configured to sit within the neck section of the housing on top the torque spring. A bit holder and driver mechanism are rotationally mounted within the bottom section of the housing. When the torque threshold is reached by the bit holder, the driver mechanism rotationally disengages from the bit holder.
