Abstract: A reaming tool includes a main tool body disposed about a rotational axis, a plurality of peripherally arranged cutting inserts coupled to the tool body, and a fine adjustment mechanism associated with each cutting insert. The adjustment mechanism includes an adjusting screw with a conical section that acts on the cutting insert for fine adjustment, the conical section being arranged between a first and a second cylindrical guide section. The two guide sections ensure high-precision guidance of the adjusting screw.

Abstract: A rotating cutting tool includes a single or multi-piece support part having an end face and a circumferential wall, an interchangeable cutting insert provided at or about the end face, and at least one interchangeable guide insert coupled to the support part via a retaining means. The at least one interchangeable guide insert being free of cutting edges and protruding radially relative to the circumferential wall. The at least one interchangeable guide insert including a guide section which protrudes radially furthest outward. The guide section lying axially at the level of the retaining means and offset from the retaining means in the circumferential direction.

Abstract: A tool interface that is easy to produce but also precise, for coupling a tool head to a tool shank in a centered manner in respect of a shank axis, comprises a first interface part that is connected to the tool shank or to the tool head, and a second interface part that is connected to the respectively other tool part, namely, to the tool head or to the tool shank. The two interface parts have interface surfaces that substantially complement each other and are intended to bear flatly on each other. The interface surface of the first interface part comprises an inner cone surface and an outer cone surface, which surrounds the latter on the outside and coaxially. The interface surface of the second interface part comprises an outer cone surface, which corresponds with the inner cone surface of the first interface part, and an inner cone surface, which corresponds with the outer cone surface of the first interface part.

Abstract: A tool interface (5) that is easy to produce but also precise for coupling a tool head (2) to a tool shank (3) in a centered manner in respect of a shank axis (4), comprises a first interface part (6) that is connected to the tool shank (3) or to the tool head (2), and a second interface part (7) that is connected to the respectively other tool part, namely, to the tool head (2) or to the tool shank (3). The two interface parts (6, 7) have interface surfaces (9, 10) that substantially complement each other and are intended to bear flatly on each other. The interface surface (9) of the first interface part (6) comprises an inner cone surface (21) and an outer cone surface (22), which surrounds the latter on the outside and coaxially.
