Walter has introduced the TC620 Supreme thread milling cutter, which has a multi-row design that exerts low cutting forces, reduces deflection, and enables excellent dimensional accuracy.
The tool is suitable for producing J-thread profiles, which are intended for aerospace and other applications in which threaded components experience high-temperature and high stress levels.
J-threads feature a root radius that improves the tensile strength of the connection by reducing the stress concentration factor in the thread, making the thread more reliable. The usable length of the tool is up to 2.5 × DN in the standard program. The primary application is threading stainless steel and heat-resistant super alloys with a hardness up to 48 HRC (ISO material groups M and S), and the secondary application is cutting steel, cast iron, and non-ferrous metals also up to 48 HRC (ISO material groups P, K and N). The tool is ideal for difficult applications, such as threading Inconel 718, and ones that require a high level of process reliability.
The thread mill is made of the high-performance grade WB10RA carbide, which is the first choice when thread milling nickel-base and titanium alloys. The tool features internal coolant for reliable chip removal even when machining at a high feed per tooth. The cutter provides low costs per thread due to long tool life capabilities and short machining times. In addition, it enables high process reliability and easy handling, as radius corrections are extremely rare.
The Walter lineup of products consists of three categories to its tools. Supreme indicates the highest level of technology and performance available. Perform tools are products that provide an economical solution with focused importance on price, and Advance indicates a product efficiently balanced between price and performance.
