Abstract
A drill press includes a spindle pulley having a first central opening extending along an axis, a sleeve disposed within the pulley central opening, the sleeve having a central opening aligned with the pulley central opening and the axis, and a locking nut connecting an upper end of the sleeve with the spindle pulley for supporting simultaneous rotation of the sleeve and the spindle pulley about the axis. The drill press includes a spindle disposed within the sleeve central opening and extending along the axis, the spindle being slidable along the axis relative to the sleeve and being rotatable with the sleeve. The drill press includes a spacer disposed between the spindle and the locking nut or between the spindle and the sleeve for aligning the spindle with the axis and preventing the spindle from contacting the upper end of the sleeve during rotation, which reduces noise during operation.
