ABSTRACT:
A variable speed direct drive drill press/router is disclosed. The drill press/router includes a housing supported above a horizontal bed which contains a generally vertically extending spindle that is rotatably mounted within and partially extends below the housing. A manually engageable or motor driven driver axially moves the spindle predetermined distances toward and away from the horizontal bed. For driving the spindle, a switched reluctance motor is mounted at the upper end of the housing for rotary driving engagement at a desired range of predetermined speeds throughout the entire range of axial movement of the spindle. The lower end of the spindle is capable of interchangeably receiving a workpiece rotating tool such as a drill or router for drilling or routing a workpiece.
