    Abstract: The invention describes a rotary cutting tool, in particular a drill, which comprises a first cutting tool part having at least one cutting edge and a second cutting tool part which comprises a cutting tool shank. The first cutting tool part and the second cutting tool part are releasably connected to one another via a coupling mechanism which comprises a coupling cam that is mounted on one of the two cutting tool parts such that it can rotate about an axis of rotation and, in a coupling position, abuts an engagement surface on the other cutting tool part. The invention also presents a cutting tool part, in particular a cutting tool base, and a further cutting tool part, in particular a cutting tip.

    Abstract: A modular boring head includes a tubular main body having an internal thread with a first pitch and a pair of axially extending cantilevered members. A movable rod engages the tubular main body such that the movable rod is movable with respect to the tubular main body in an axial direction, D. The movable rod has an internal thread with a second pitch different than the first pitch. A leadscrew is disposed within the tubular main body and has a plurality of gear teeth. Rotation of the leadscrew causes the pair of axially extending cantilevered members of the tubular main body to cooperatively engage with the plurality of gear teeth of the leadscrew in such a manner so as to produce an audible and tactile click, each click being indicative of a distance the movable rod is displaced with respect to the tubular main body.

    Abstract: A device for adjusting an adjustment mechanism of a cutting tool includes a main body disposed about a longitudinal axis. The main body has a handle portion disposed at or about a first end of the main body which is structured to be gripped by a hand of an operator and a feature structured to engage a correspondingly-shaped feature of the adjustment mechanism disposed at a second end of the main body opposite the first end. The device further includes a first element fixedly coupled to the main body; a second element rotatably coupled to the main body such that the second element is freely rotatable about the longitudinal axis, the second element having a total mass which is disposed unevenly about the longitudinal axis; and an arrangement for determining the relative positioning of the second element in regard to the first element.

    Abstract: A cutting tool includes a base body and a cutting head at least partially disposed within a modular pocket of the base body. The modular pocket is formed by at least one wall section removably attached to the base body. In one variation, a non-removable portion of the base body also forms part of the modular pocket. In another variation, the modular pocket is formed by two removable wall sections on opposite sides of the modular pocket. In yet another variation, the removable wall sections include a clamping portion to exert a downward force on the cutting head to enable mounting the cutting head in the modular pocket using an interference fit.
