ABSTRACT:
A thread cutter for pipe ends has a tool head rotating coaxially with respect to a fixedly clamped pipe end and provided at tool holders in the form of radial sliders. Actuators which are parallel to the rotation axis are mounted on a frame shiftable with respect to the head for synchronously radially displacing the sliders and gears mesh with racks of neighboring sliders. The gears are formed with an integrated centrifugal force balancing system.
