Abstract: A tool has a tool carrier having a tool cassette with a main body, into which an insert seat for receiving the exchangeable cutting insert is recessed and which has a guide, extending along a direction of adjustment, for an adjusting element for adjusting the position of the main body in the cassette seat in the direction of adjustment. The main body has a first mating surface and at least one second mating surface, wherein the first mating surface extends transversely to the direction of adjustment and the second mating surface extends in the direction of adjustment, and the mating surfaces are configured for the precisely fitting contact against a corresponding first and second contact surface of the cassette seat.

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

Abstract: A twist drill includes a drill body having a chip flute extending a distance along the drill body. The chip flute has a leading edge and a run-out edge running along the chip flute. The run-out edge is disposed behind the leading edge in a direction of rotation of the twist drill. The chip flute, viewed cross-sectionally in a direction perpendicular to the longitudinal axis, includes a first wall portion and a second wall portion. The first wall portion extends along a curve between the run-out edge and the second wall portion. The second wall portion extends in a straight line from between the leading edge and the first wall portion. The first wall portion and the second wall portion are disposed adjoining one another and together define a J-shaped cross-sectional profile perpendicular to the longitudinal axis.

Abstract: In the case of a cutting insert, in particular for counterboring and/or countersinking operations, the cutting insert has two longitudinal sides and two narrow sides between an upper side and an underside. A cutting edge is formed between one longitudinal side and one narrow side and runs obliquely in relation to the underside and extends over at least approximately the entire depth of the cutting body. A cutting face running between the upper side and the underside is provided in the longitudinal side that is facing the cutting edge.

Abstract: A tool cassette having a receptacle for an interchangeable cutting insert, wherein at least one setting element for setting the position of the tool cassette with respect to a seat for the cassette of a carrier tool is provided on the tool cassette.

Abstract: An insert includes a body portion and at least one cutting edge disposed on the periphery thereof. The cutting edge includes an inner lip and an outer lip disposed at an angle with respect to one another. A line extending along the inner lip intersects with a line extending along the outer lip at the vertex of the angle. The angular cutting edge further includes a protuberance disposed between, and connecting the inner and outer lips and projecting outwardly away from the body portion beyond the vertex of the angle defined by the intersection of the lines extending from the inner and outer lips. The protuberance having an inner lip connected to the inner lip of the cutting edge and an outer lip connected to the outer lip of the cutting edge to form smooth curvilinear transitions between the lips of the protuberance and the lips of the cutting edge.

Abstract: A cutting insert has the geometry of a tetrahedron with triangle base areas wherein each triangle base area has a tetrahedral frustum as a clamping body for fixing the cutting insert in a tool seat of a carrier tool. Additionally, a tool seat for the cutting insert includes clamping jaws to secure the cutting insert.

Abstract: A drill includes a tool body having a fluted portion having a second end and a tool head portion, having a cutting tip and at least one cutting edge, removably connected to the second end of the fluted portion. The fluted portion includes a receiving pocket disposed in the second end and is defined by a peripheral side wall extending about the periphery of the receiving pocket. The tool head portion includes a driving projection configured to be inserted into the receiving pocket. The driving projection and receiving pocket have corresponding elongated, curvilinear, dog-bone shapes. The driving projection includes a first end portion, a second end portion, and a central portion disposed between connecting the first end portion and the second end portion. The first end portion and the second end portion each have a width that is substantially greater than a width of the central portion.

Abstract: A twist drill having at least two cutting inserts at the tip each with its own J-shaped chip guiding flute and a method for the production thereof.
