摘要： A pressure foot (7) of a perforating machine for a printed board, which is supported axially slidably on a spindle (2) of the same machine, and has a presser surface (13) for press holding a printed board (5) during perforating process, a discharge port (11) formed in a side wall (8) for discharging cutting chips produced by processing for perforation, the discharge port (11) being connected to a suction device, and a compressed air supply passage (20A) formed in the side wall for blow out compressed air toward a drill (4) of the perforating machine for a printed board. A cooling liquid supply device (21) is connected to the compressed air supply passage (20A). A liquid supply passage (14) for injecting cooling liquid toward the drill (4) of the perforating machine for aprinted board may be formed instead of the compressed air supply passage (21A). In this case, there is formed at least one groove (18) extending in the direction of a tangent to the drill (4) for allowing air to be sucked into the interior (10) of the pressure foot in the presser surface (13). This enhances cooling efficiency during perforating process.
