A machine reaming tool includes a base body with a plurality of insert receivers with cutting inserts that are inserted therein. The cutting inserts are inserted into insert receivers that each form a linear guide of the cutting inserts in a direction orthogonal to a rotation axis of the machine reaming tool. The linear guide is a prismatic sliding guide such as a dovetail guide. In particular, the dovetail guide is designed asymmetrically.

A reamer or similar tool comprising a cutting device having a cutting edge, a clamping device, whereby the cutting device can be clamped to the main body of the tool, an adjusting device that interacts with the cutting device, for adjusting the machining diameter of the tool, and a guiding device comprising an elongated guiding element, which interacts with an elongated guiding receptacle such that the cutting device can be guided in a sliding manner perpendicularly to the center axis during a displacement when the adjusting device is activated. The guiding element and the guiding receptacle extend perpendicularly to the center axis of the main body of the tool. The guiding device of the tool has a single guiding element and/or a single guiding receptacle, and the guiding element has an elongated elevation and the guiding receptacle has an elongated recess.

A machining tool having has a body that includes a central tubular portion forming a duct centered on a longitudinal axis. A peripheral tubular portion is coaxial with the central tubular portion and surrounds the central tubular portion. A first machining stage has a first arm and a second arm that extend on either side of the central tubular portion. The first arm and the second arm each have a machining member at the end thereof. The first arm and the second arm are each integral with the central tubular portion and the peripheral tubular portion. The machining tool body also includes a baseplate. The peripheral tubular portion has at least one linking arch connecting the first arm and the second arm and bypassing the central tubular portion.

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.
