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.
