An adjustable angle toolholder comprising a shank and an adjustable head is provided. The shank has a first end and a second end. The first end is adapted to be held in a machine, such as a lathe. The second end includes a fixed plane oriented parallel to a lengthwise direction of the shank. The fixed plane includes an arcuate face at a distal end of the fixed plane. The head has a fixed plane that mates with the fixed plane of the shank. The fixed planes of the shank and head include a pivot hole through which a pivot bolt passes. The pivot bolt allows adjustment of the head through a wide range of angles relative to a lengthwise direction of the shank, while the fixed planes maintain a position of a centerline of a cutting tool constant with respect to a centerline of the shank. The fixed plane of the shank may be on a centerline of the shank.

For producing a cylindrical surface that has a surface structure of predetermined geometry suitable for application of material by thermal spraying, a geometrically predetermined groove structure of minimal depth and width is introduced into the surface by a tool embodied as a follow-on tool in that a groove cross-section is processed successively to a final size. In order for the surface to be producible in mass production with constant quality, the groove structure is worked in such that first a base groove is introduced with a groove bottom width that is smaller than the groove bottom width of the finished groove. Subsequently, at least one flank of the base groove is processed for producing an undercut groove profile by a non-cutting action or cutting action wherein the introduced groove structure is deformed in such a way that the groove openings are constricted by upsetting deformations of material.
