Abstract: A work table for machine tools such as pillar-type drills and the like comprising a substantially horizontal plate forming a work surface through which are cut a plurality of longitudinal or radially extending grooves. A flange depending from the peripheral edge of the horizontal plate is supported on a base plate and is provided with a plurality of vertical openings aligned with the grooves in the work surface. A clamping plate is mounted to move vertically beneath the work surface within a space defined by said flange and said base plate and is also provided with grooves arranged in alignment with the grooves in the work surface. The clamping plate is connected to power transmission means which allows the clamping plate to be moved into positions which are inclined relative to the work surface.
