ABSTRACT:
A combined sawing and drilling machine for structural steel shapes such as I beams has a circular saw unit and the drilling unit mounted on a common plate or on respective plates on a common foundation adjacent one another so that the clamping screw for replacement of the blade is actuated through a window or opening in the plate carrying the drill units, thereby allowing the drilling unit and the saw to be disposeed closer together when the roller conveyor is equipped with only one position-measuring unit and thereby reducing cut-off waste.
