Premium threading tools

As an innovative manufacturer of precision tools for machining, Walter offers you efficient solutions for all common thread production methods: Whether for tapping, for internal threads in through holes and blind holes, or for external threads too. No matter whether the methods are non-cutting, such as thread forming, or cutting, such as thread cutting or tapping, thread milling or thread turning: The high quality of Walter's threading tools helps achieve particularly high productivity, process reliability and cost-effectiveness. In all commonly used materials, as well as in really special ones. When machining workpieces in general mechanical engineering as well as in mould and die making, in the automotive, energy or aerospace industries.

Cutting methods for thread production

The comprehensive complete range of tools for machining various materials and diameters includes a wide variety of taps with the highest levels of precision, quality, cost-effectiveness and process reliability in addition to turning and milling tools for thread production and compatible toolholders and indexable inserts. For tapping, especially sophisticated threading tools made from high-performance solid carbide and high-speed steel (HSS-E, HSS-PM) cutting tool materials are available from Walter. High-quality coatings tailored to the material to be machined help to achieve production goals such as dimensional stability, short machining times, long tool life and outstanding results when producing threads. In addition, the form and geometry of our taps ensure low wear and greater efficiency – for example through improved chip removal using optimised flutes and rake angles. As a result, our solid carbide taps also meet the high requirements for production of all thread types, e.g. in the automotive industry. When it comes to thread turning, Walter impresses with threading tools which feature one or more cutting edges and have been developed for precise production of all common internal threads. In the case of turning and milling tools for thread production, highly robust tool holders and ISO boring bars, ISO square shanks and threading inserts with cutting edges of different lengths (11, 16 and 22 mm) and compatible indexable inserts complete the range. Full profile and partial profile versions of our three-edged indexable inserts, for example, are ideal for all common external and internal threads. These different indexable insert versions make it possible to produce complete and absolutely precise threads with the highest surface finish quality and dimensional accuracy. Besides thread mills made from different cutting tool materials (solid carbide), the wide selection of Walter thread milling cutters also includes indexable insert milling tools. These indexable insert milling tools make it possible to produce external and internal thread diameters in all common sizes and materials on CNC machining centres. From steel and stainless steel to cast iron, non-ferrous metals, such as aluminium, right through to titanium, tungsten and molybdenum alloys and hardened steel – regardless of the thread profile and thread pitch. With us, you can always find the right tools for virtually all applications, depths of cut and workpieces. Orbital thread milling, for example, also makes it possible to produce very deep and also very small internal threads. Completely reliable, even in demanding materials. 

Non-cutting methods for thread production

Thread forming is often the most cost-efficient method of producing threads. Through the targeted further development of the forming edge geometry, the precisely adapted cutting tool material alloys and the high-performance surface coatings of our thread forming tools, virtually all formable materials can be provided with internal threads using this method. The innovative geometry of our threading tools ensures a particularly high surface quality of the thread – for both small and large threads. Innovative new coatings, the special surface treatment and, for example, the optimised polygonal shape of the tools also result in reduced friction for virtually any pitch and any thread diameter. For deep threads, tool versions with radial internal coolant and lubrication are the first choice. The main advantages of our thread forming tools include reduced cooling lubricant costs and fewer tool changes in addition to high forming speeds and a long tool life – which ultimately leads to optimum machine utilization when thread forming.
