Abstract (en)
This device is of the type in which the tool (5) is mounted so that it can slide, with the interposition of upper and lower guide means, in a front guide (2). According to the invention, at least one of the guide means (4a) delimits a guide zone the directrix curve of which comprises points of inflection forming corners (10) for separating the facets (12), the zone interacting with a zone of complementary cross-section formed, at least locally, on the tool (5) for wedging this tool in terms of rotation. <IMAGE>
