ABSTRACT:
The present invention relates to a punch (30) and punch assembly (2) for use in a tool (1) for joining ductile materials, such as metal sheets (7,8), in a lance joint or a clinch joint. The punch (30) has a punch body (31) formed around a punch axis (5). Two punch tips (34,34′) extend in opposite directions from the punch body (31) along the punch axis (5). The punch body has one or more load engagement features (41,41′) by which a punch force for joining the ductile materials (7,8) is imparted to the punch body (31). When one punch tip (34) becomes worn, the punch (30) can be removed from a punch holder (25), inverted and rejoined to the punch holder (25) so that the other of the punch tips (34′) can be used to join ductile material (7,8)
