Surface roughening tool with translatable swaging blades

A surface roughening tool comprising:

• a cylindrical body;
• one or more axial rows of grooving elements outwardly radially projecting from the body, each row situated along a circumference of the body, with each of the grooving elements having a retracted position and an extended position;
• and
• one or more axial rows of swaging elements outwardly radially projecting from the body, each row situated along the circumference corresponding to each row of the one or more axial rows of grooving elements, each of the swaging elements having a corresponding fixed distal end forming a fixed swaging circumference concentric with the circumference of the body,
• wherein in the extended position, each grooving element has a distal end positioned radially outward of the fixed distal ends of the swaging elements to form an extended grooving circumference radially outward of the fixed swaging circumference, and in the retracted position, the distal end of each grooving element is positioned radially inward of the fixed distal ends of the swaging elements.
