Abstract
A cutting tool includes first and second components, configured for differential coupling with each other. The first and second components each include peripheral and central coupling threads which each extend in a helical direction about a component axis of the respective component. Each component's peripheral and central coupling threads are axially offset with respect to each other. The first and second components each include a radial stop surface located at the respective peripheral coupling thread. In an assembled position of the cutting tool, the radial stop surfaces abut each other and the peripheral and central coupling threads of the first component threadingly engage the peripheral and central coupling threads of the second component, respectively, forming a differential tool coupling between the first and second components.
