Walter expands thread former range 23 February 2021

Walter AG has added two new tools to its product range – the new TC420 Supreme thread former (M5 – M16), as well as a metric variant (M24) with radial internal cooling for blind and through threads.

Both new tools are optimised for maximum performance in universal use and feature a new combination of gate shape E and a geometry without lubrication grooves. This improves lubrication and at the same time reduces torque by up to 30% – with a corresponding increase in tool life.

In addition to very high cutting data and tool life, users benefit from good surfaces with the new tools. The thread formers also show up to 30% higher pull out strength under dynamic loads compared to other methods, which in turn increases the thread quality for highly stressed workpieces.

Walter offers the new TC420 Supreme thread formers for medium to large lot sizes, with and without lubrication grooves, as well as with axial, radial and without internal cooling – either with a TiN coating (type WW60AD) or as a TiCN variant (WW60BA). Typical areas of application are general mechanical engineering and the automotive and energy industries.
