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: The milling cutter, in particular a round-head milling cutter, has a tool head, which extends along an axial direction and has a number of cutting teeth that each have a cutting edge. Chip flutes are located between each of the cutting teeth. The cutting teeth each have a front-side radial portion and a circumferential axial portion. The respective cutting edge and the chip flute are disposed such that they are inclined in opposite directions with respect to the axial direction such that the cutting tooth widens towards a foot region. In another embodiment, the tool head has two parts: a carrier part made of a tool steel, and a cutting part made of hard metal fastened to the carrier part. The milling cutter is distinguished by a long service life with a high cutting rate and a high quality of machining.

Abstract: A tool head (10) for a rotating tool (2) includes a basic body (8), an annular portion (12) arranged on an end face on the basic body (8) and surrounds a cavity (22), and an adjusting device (18) including an adjusting screw (32) with a shank (34) and an adjusting sleeve (20). The shank (34) having a first shank portion (36) engaging a threaded bore (44) in the basic body (8). The adjusting sleeve (20) is displaceable by the adjusting screw (32) and has a conical outer face (30) that interacts with an inner face (28) of the annular portion (12) in such a way that, when the adjusting screw (32) is being screwed into the threaded bore (44), the annular portion (12) is spread open by the adjusting sleeve (20).

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: The tool holder (2) is realized for fastening to a machine tool and for reversibly receiving a radial tool (4), in particular for receiving a milling cutter. The tool holder (2) is realized in three parts, having a rear machine part (6), made of a ductile elastic tool steel, for reversibly fastening to the machine tool, and having a front clamping part (10), made of a tool steel, for reversibly receiving the tool (4), and having an intermediate part (8), made of a heavy metal, in particular solid hard metal, disposed between the machine part (6) and the clamping part (10). Owing to the greater density of the heavy metal in comparison with the tool steel, the tool holder (2) is better able to absorb forces occurring during a milling operation, thereby achieving a milling operation that is sparing of the cutting tool, and consequently achieving a long service life.

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.
