Thread Former Boosts Productivity and Quality

The Protodyn HSC provides a thread production process that creates no chips, bird nesting, or chip removal problems
Walter USA, LLC has introduced the Walter Prototyp Protodyn HSC thread former, a solid carbide tool engineered to boost thread forming cutting speed, productivity and tool life. The Protodyn HSC provides a thread production process that creates no chips, bird nesting, or chip removal problems, yielding a high level of process reliability even for deep hole and through hole threads. It also has a new micrograin carbide substrate that promotes both superior toughness and wear resistance. This substrate is mated with a hard multilayer TiCN coating that helps make the Protodyn suitable for use in all formable materials, such as steel, stainless steel and aluminum materials with an Si-content of less than 12 percent. The innovative geometry of the Protodyn HSC also provides additional benefits. It possesses a shank tolerance h6 for use in shrink-fit chucks, and its optimized polygonal form reduces friction and increases tool life, leading to fewer tool changes and an attractive price/performance ratio. Its new chamfer geometry promotes uniform wear. For deeper than normal threads - up to 4xD - the Protodyn(S) HSC version of this new generation solid carbide thread former features axial internal coolant, with cutting speeds that are twice as high as an HSS thread former. Finally, a another key advantage is that their formed threads' high level of tensile strength, due to cold work hardening of the flanks and profile, yields tough, high quality threads.
