Thread Milling Combines with Thread Tapping

July 18, 2017
Walter USA LLC combines thread milling with thread tapping in the T2711 / T2712.

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


With the 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 1 in. (24 mm) and above.


A few benefits of the thread milling cutter include easy-cutting geometry, wear-resistant, and 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 and materials up to 55 RC can be machined. 


  • low costs per thread due to fast machining (in many cases faster than thread tapping and forming)
  • easy handling and few radius corrections
  • excellent thread quality due to smooth operation
  • high cutting speeds and high feeds per tooth
