Specially made for the machining of austenitic stainless steels, the twist drills EF-Drill-VA are available in the designs acc. DIN 6537 short (3 x D) and long (5 x D).
Depending on the material to be machined, the extended cutting part and the long chip flutes of these machine taps permit the production of thread depths up to 4 x d1. These machine taps are now available in sizes from M20 to M48.
An increased number of flutes, plus a redeveloped geometry and a general optimization in relation to the standard GSF and GF series, permit faster machining, a smoother operation, and, as a result, increased tool life.
