The invention relates to a cutting tool (10) and a tool holder (17) for cutting panels from blanks of sheet-like material. The cutting tool comprises a thin cutting plate (12) on which is formed by etching a cutting edge (14) having a contour corresponding to the outline of the panels to be cut out. The cutting plate also comprises a plurality of openings (16) which are surrounded by the cutting edge. The tool holder is a metallic cylinder (17) to be mounted on the drive shaft (53) of a conventional panel cutting apparatus and comprises a seat (26) for receiving the cutting plate which is retained in the seat by keys (30). In the cylinder are formed passageways communicating with a source of vacuum and also communicating with the openings on the cutting plate to create a zone of vacuum in the vicinity of the cutting edge. |
