ABSTRACT:
A feed system for a drill press. The drill press comprises a base for supporting the drill press on a surface, a housing supported on the base and defining an opening, a telescoping spindle assembly positioned for movement relative to the housing along an axis and for rotation about the axis, a motor operable to rotatably drive the spindle assembly, a drive system connected between the motor and the spindle assembly, and a feed system for moving the spindle assembly between a lowered position and a raised position. The feed system is supported by the housing so that a portion of the feed system is exposed through the opening. The drill press also comprises a flexible barrier member to cover the exposed portion of the feed system. The feed system includes a sprocket rotatably supported by the housing and a flexible member movably engaging the sprocket and connected to the spindle assembly such that rotation of the sprocket moves the spindle assembly between the lowered position and the raised position.
