Abstract: A modular drill apparatus (100) includes: a shank (110) having a pocket (112); a cylindrical post (117) centrally secured within a bottom (114) of the pocket (112); a cutting tip (130) including a lower portion (131) including a central bore (136) which receives the cylindrical post (117), an upper portion (132) and a channel (134) therebetween; and an insert assembly (150) interfitted within and supported by the channel (134), the insert assembly (150) being expandable along a length thereof for securing the cutting tip (130) to the shank (110) within the pocket (112) by providing an interference fit and retractable along the length thereof for releasing the cutting tip (130) from the pocket (112) by overcoming the interference fit.

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 boring head includes a housing having a first end configured to be coupled to a machine tool and a second end positioned opposite from the first end with the housing defining a central passageway. The boring head also includes a diameter adjustment mechanism comprising a sliding holder received by the housing and movable relative to the housing with the sliding holder configured to be coupled to a cutting insert and a balancing mechanism having a balancing mass. The balancing mechanism is configured to move the balancing mass when the sliding holder is moved. The balancing mass is aligned with the sliding holder in a direction extending about perpendicular to a longitudinal axis of the housing.
