Abrégé
(EN)

A ratchet bit driving tool includes a hexagonal tool driving shaft with planar faces and vertices between the faces; a handle drive sleeve with a cylindrical inner bore and adapted for attachment to a handle; and a roller bearing ratchet clutch with an annular roller bearing cage between the tool driving shaft and handle drive sleeve which is adapted to selectively engage the tool driving shaft on rotation of the handle drive sleeve. The roller bearing cage includes at least three roller bearing apertures in separated by at least three resilient locator bars with a substantially cylindrical roller bearing resiliently retained in each aperture between a face of the tool driving shaft and the handle sleeve by the locator bars. The roller bearing cage additionally includes at least three inwardly facing resilient position indexing notches operable to engage with a vertex of the tool driving shaft.
