Walter's new thread milling cutter with tapping benefitsClick image to enlarge

Walter has introduced what it says is the first thread milling system to combine the advantages of thread milling with those of thread tapping.

With Walter's new T2711 / T2712, multiple thread sections can be machined simultaneously with high cutting parameters, enabling machining times comparable to those of thread tapping and forming, to be achieved. In addition to quick machining, users also benefit from the high process reliability of the thread milling process and the cost benefits of an indexable insert tool. The new tool is ideal for machining larger threads with diameters of 25.4 mm (1 in.) and above.

Together with ease of handling and excellent thread quality, the high level of productivity at low cost per thread due to fast machining (in many cases faster than thread tapping and forming) is a major benefit, according to Walter. In a test involving large-scale crankshaft machining, the new thread milling cutter reduced costs by 60 per cent. Additional benefits of the new T2711 / T2712 thread milling cutter include easy cutting geometry and wear resistant, universal grade WSM37S.

The Walter T2711 / T2712 is a universal indexable thread mill for thread depths up to 2.5 DN and a pitch range of 8-18 TPI for UNC and UNF thread styles (1.5-6 mm for M and MF threads). The mill is suitable for ISO P, M, K, S and H. Materials up to 55 RC can be machined. For specials there are virtually no size limits and thanks to Walter Xpress, special tools can be provided with a delivery time of only three weeks.
