A drill press assembly having a base mountable to a work bench, a vertical column attached to the base and a drill head assembly having an electric motor and a quill. The drill head assembly is movably attached to the column. A rack is rotatably attached to the top of the column and is engaged by a crank and pinion mechanism attached to the frame of the drill head assembly which permits the drill head assembly to be displaced vertically and rotated about the column. A tilt table is attachable to the base of the drill press. A locking mechanism having a bolt passing through a longitudinal slot in the supporting base of the tilt table and a transverse slot in the base is engaged by an eccentrically mounted camshaft to lock the supporting base of the tilt table to the top surface of the drill press base. A pivoting frame is pivotably attached to the supporting base and contains a table plate. A fence is attachable to the top of the pivoting frame. The fence has a stopping block to facilitate the location of a workpiece on the tilt table. A work clamp is also provided on the drill head assembly to clamp a workpiece on the tilt table.
