TUBINGEN, Germany, Sep 15, 2025 – Walter is launching a world first on the market with the multi-row thread milling cutter TC620 Supreme with 90° countersink chamfer and Walter DeVibe anti-vibration geometry. For the first time, the benefits of multi-row thread milling cutters are combined with an integrated countersinking function. Compared to solutions with conventional thread milling cutters, users benefit from specific advantages: from the parallel machining of several thread sections to the high process reliability of multi-row thread milling cutters due to lower displacement forces, easy handling thanks to rare radius corrections, to time savings because countersinking and threads are created in the same operation – and with the same tool. In addition to the separate countersinking tool that would otherwise be required, the user also saves change-over time, storage capacity and space in the tool magazine.
Like the thread milling cutter without countersink chamfer, the TC620 Supreme with 90° countersunk chamfer also features Walter’s patented DeVibe anti-vibration geometry. This significantly increases the tool’s operational smoothness, prevents so-called “chatter marks” and improves thread quality. The multi-row design reduces cutting forces and guarantees high dimensional accuracy of the tool. The internal coolant supply optimizes chip removal at high feed per tooth. The bottom line is that this ensures reliable machining even under extreme conditions. Walter offers the combination tool up to 2 × DN in all common diameters (M3-M20) and thread profiles (such as Metric, Metric Fine, UNC/UNF, etc.). Users can thus benefit from high process reliability and low costs per thread in a wide range of applications – with high tool life quantities and up to 50 % shorter machining times.
