Summary:The invention pertains to a tool layout (10) for making boreholes (12) in materials (14) such as fiber composite materials, comprising a cutting tool (16) with a drill shaft (20) having a suction channel (18) and with a drill head (26) having at least one tool blade (22, 24), wherein the drill head (26) has a larger diameter DBK than the drill shaft (20) in order to form an intermediate space (28) between drill shaft (20) and the wall of the borehole, and a suction device (30) coupled to the suction channel (18) of the drill shaft (20) to suction away the shavings removed through at least one suction opening (32, 33) of the drill head (26) coordinated with the at least one cutting blade (22, 24) into the suction channel (18). To improve the suctioning of the shavings and/or the cooling of the tool and work piece, an outer wall (64) of the drill head (26) has at least one recess (64, 66) extending for the entire length of the drill head (26) and emerging into the at least one suction opening (32, 33) as a crossover channel by which a connection is produced between the intermediate space (28) bounding the drill shaft and the suction opening (32, 33).
