    摘要： The invention discloses a drilling tool (1) having at least one chip groove (2) for chip removal, having an insert seat (4) which is formed at the end of the chip groove (2) and serves as a holder for an indexable insert (3) with at least one main cutting edge (10) on the two narrow sides and with at least one secondary cutting edge (9) on the two longitudinal sides of one face side, wherein the indexable insert (3) has two face sides facing away from one another and bears with its inactive face side on a holding surface of the insert seat (4), and a partial region of the inactive secondary cutting edge (9) of its active face side lies in the insert seat (4) at a distance from the adjoining side wall (11) of the insert seat (4) created by a slot, and wherein a guide lip (12) which covers the slot protrudes out of the top side of the side wall (11) in the direction of the inactive secondary cutting edge (9).

    摘要： A clamping tool holder (10, 100) includes a tool holder body (12) and a clamp (40) for clamping a cutting insert (22). The tool holder body (12) has an inclined surface (34) sloping inward in a direction away from the insert-receiving pocket (14). The clamp (40) has an inclined surface (50) that acts as a ramp with the inclined surface (34) of the tool holder body (12). A guide pin (60) prevents the clamp (40) from twisting during tightening or loosening of the clamp (40). When a clamp screw (52) is tightened, a nub (48) of the clamp (40) engages an inside rearward surface of a mounting bore (24) of the insert (22) along a line of contact (48a) and exerts a force downward and rearward on the insert (22).

    摘要： A cutting tap (20, 40) includes a body (22, 42) having an axial forward end (24, 44) and an axial rearward end (26, 46) and a central longitudinal axis (Z-Z). The body has a fluted section (30, 50) at the axial forward end. The fluted section includes a chamfered fluted section (54) extending from the axial forward end of the body and terminating at a first full cutting thread (70). The chamfered fluted section includes a first cutting thread (62, 66, 68) located a first distance from the axial forward end of the body, and a second cutting thread (62, 66, 68) located a second distance from the axial forward end of the body. The second distance is greater than the first distance. The chamfered fluted section is shaped such that a thickness of a section of material removed by the second cutting thread is smaller than a thickness of a section of material removed by the first cutting thread. A method of making the cutting tap is also disclosed.
