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.

Sophisticated roughing operations in High Performance Cutting (HPC) ­demand extremely high clamping forces, which usually can only be reached by form closed clamping (e.g. side-lock). The cause of this pull-out happens due to a micro-creeping motion of the tool inside the chuck, as is the case when using shrink-fit chucks with high cutting-speeds and high pull-out forces. The combination of spiral-fluted grooves in the tool shank ends, gripped by form closed drive keys inside the chuck and the counter-rotating load on the cutting-edge provides an enhanced fixing of the tool.

The latest model series Softsynchro® Modular combines the well-proven patented technology of the Softsynchro® minimum length compensation with the required flexibility of tool equipment in modern production. The modular set-up allows the length adjustment of threading tools with male or female centered tool shanks. The HSK shank adaptation to the machine spindle can be adjusted for 1- and 2-channel minimum quantity lubrication systems as well as fluid lubrication. The loss-free transfer of the lubrication medium and the effectiveness of the Softsynchro® technology result in a clear improvement of the thread cutting process and are unique on the tap holder market.
