Taps for Higher Productivity in Hardened Steel



Walter's TC388 and TC389 Supreme solid carbide taps are engineered for solving key problems in threading hardened steel, in part because producing threads in hardened steel has traditionally been 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," said a company spokesperson.

Walter solves this problem with the TC388 Supreme (50-58 RC) and TC389 Supreme (55-65 RC) with their 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," said the spokesperson. "Furthermore, the taps are coated using Walters' HiPMS coating technology, which creates a better surface finish and higher thread form quality due to this innovative 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 x DN."
