New Walter taps for higher productivity, reliability and quality in hardened steel
Walter has introduced the TC388 and TC389 Supreme solid carbide taps, for solving key problems in threading hardened steel, in part because producing threads in hardened steel has traditionally been both costly and time consuming. This especially applies to blind hole machining in particular because reversing the tap during this process can cause torque peaks when the root of the chip is sheared off, resulting in tool failures.
Walter solves this problem with the TC388 Supreme (50–58 RC) and TC389 Supreme (55–65 RC) with their new patent-pending cutting geometries that fully shear off the root of the chip when reversing, thus torque peaks are minimized. This prevents fractures, prolongs the tool life, and increases process reliability. Furthermore, the new taps are coated using Walters new HiPMS coating technology which creates a better surface finish, and higher thread form quality due to this innovative new coating process. Lubrication with oil, which was often necessary until now, is no longer required. Instead, standard water-based emulsions can be used, optimizing handling and saving additional machining costs. The TC388 and TC389 can be used for tapping both blind-hole and through-hole threads up to 2 × DN.
The Walter lineup of products consists of three categories to tools. Supreme tools indicate the highest level of technology and performance available. Advance tools indicate product efficiently balanced between price and performance and Perform tools are products that provide an economical solution with focused importance on price.
