Abstract
A rotary tool (11) for use with a rotary driving unit (12) for inserting a component (14,14′,14″) through a surface of a workpiece made of a material showing friction-induced plasticity such as aluminum, includes a tool body (22) having a working end (24) defining a shoulder portion (26) and a securing device (28,28′) for selectively engaging the component to impart rotation thereof in a first direction while applying an axial force of a sufficient magnitude onto the component to produce insertion thereof by plasticizing the material through friction. The shoulder portion is provided with a deburring device (34) capable of being displaced from an inoperative position upon rotation of the tool body (22) in the first rotation direction (30), to an operative position whenever the tool body is caused to rotate in an opposite direction (30′), to provide deburring of the workpiece surface.
