Abstract
A quick connect tool, a replaceable tool, and methods are disclosed. The replaceable tool includes a shaft having a tool end, a coupling end opposite the tool end, and a longitudinal axis extending between the coupling end and the tool end. The shaft has a tool portion defining the tool end, a coupling portion defining the coupling end, the coupling portion having an outer peripheral surface shaped into a flat portion coextensive with an arcuate portion cooperatively forming a D-shaped cross-section. The flat portion and the arcuate portion extend along the longitudinal axis. The outer peripheral surface defines a peripheral groove extending transversely with respect to the longitudinal axis. The peripheral groove is configured to receive a bearing, and the outer peripheral surface also defines a bearing surface having a shape conforming to a partial spiral extending around the longitudinal axis and located at the coupling end of the shaft.
