ABSTRACT:
An improved work-supporting table particularly adapted for shiftable mounting on the support column of a drill press is provided which permits the reciprocable drill bit to cut through the entire thickness of workpiece material supported on the table surface without defacement of the latter irrespective of the drill bit position relative to the table. An arcuate groove in the table surface directly below the drill bit extends parallel to the swinging path of travel of the table relative to the drill bit and provides clearance for the bit when the latter is reciprocably advanced to the table surface. The recessed surface of the groove is covered by a strip of hardened material which is resistant to the cutting action of the drill bit thereby protecting the groove against inadvertent defacement by engagement with the bit. The groove is further provided with a T-shaped cross section to permit coupling with various workpiece holding means for clamping the workpiece material against the table surface in response to selective operation of a biasing mechanism.
