This invention is a tool for modifying the surface of a material, such as a metal for the primary purpose of improving adhesive bonding of the prepared material. The tool is a toothed burr-maker which, after application by pressure or impulse to the material to be prepared, leaves a very aggressive surface to which any adhesive will have a mechanical 'key' to bond onto the prepared surface with. The configuration of the tool is easily adapted to provide custom burrs in custom patterns and can be incorporated into a computer-guided operation to prepare selected areas of the workpiece. Self-clamping of the material is also supported through entwining of the opposing burrs. Fiber reinforcement of the bonded joint is also possible.
