High cutting pressure and tool deflection are the greatest challenges when it comes to thread milling. This results in restricted cutting parameters, necessary cutting passes, and short tool lives or even tool breakage. With the TC620 Supreme universal thread milling cutter, Walter is now transferring the functional principle of its T2711 indexable insert thread milling cutter to smaller diameters too. The multi-row concept not only reduces the machining time and wear but also improves process reliability and handling – even when used with more demanding materials such as stainless steels or Inconel 718.
Reliable chip evacuation, thanks to internal coolant, and simple handling of the TC620 Supreme guarantee maximum process reliability. Walter is launching the TC620 Supreme for thread depths of 2 and 2.5 × DN in the dimension range from M4 to M20 as well as UNC 8 to UNC ¾ – and is therefore seamlessly linking to the Walter T2711 indexable insert thread milling cutter.
