New Vergnano Taps
The new Vergnano catalogue, issue 42 2007, includes new types of taps, developed in order to fulfil growing
industrial demands regarding productivity and reliability.
Three new families of taps are available:
High performance cutting taps, P series
High performance cold forming taps, P series
Cutting taps for synchronised tapping, S series.
The new families are the result of R&D studies and represent the continuity between experience and innovation,
typical of Vergnano products.
The evolution and requests coming from the market have given origin to the new high performance taps,
P series, with higher tool life, and to the new S series taps, for synchronised tapping at high cutting speed.
The new taps have the following features:
• top quality powder metallurgy high speed steels, HSSK and HSSZ. These steels have excellent hardness and
wear resistance, ideal for applications where very high performance and productivity are required;
• state-of-the-art PVD coatings, which improve wear resistance and protect the tool from high temperatures, so
that high speed cutting is possible;
• special design to exploit both substrate and coating properties, so that high performance can be reached in
many different applications;
• internal coolant types are available, both with axial outlet for blind holes and radial outlets for through holes,
which bring improvements in tool life;
• for P series only, the taps with short chamfer (form E) are suitable in cases where a complete thread is
needed almost to the bottom of the hole.
Cutting taps are available with straight flutes and spiral point, for tapping through holes, and with spiral flutes,
for blind holes.
For additional details, please refer to the new Vergnano catalogue.
