An apparatus for punching a line of apertures in a workpiece having a channel. The apparatus comprises a punch press mounted to a base over a work space, a removable punch tool mounted on the punch press, an elongated table slidably mounted to the base having a line of travel extending through the work space, a mandrel, a clamping mechanism on the table for clamping a workpiece thereon with the workpiece channel aligned with the mandrel, and a drive mechanism for selectively moving the table in increments as the punch press sequentially strokes. When the workpiece is clamped to the table, it will be incrementally drawn along the mandrel, the mandrel being in the channel, and repeatedly punched by the punch tool, as the table is moved through the work space.
