Birmingham-based Guhring Ltd (www.guhring.co.uk) says that its latest generation of Pionex thread formers incorporates a new design that requires 30% less torque than previous product lines, thanks largely to optimisation of the groove, polygon shape and surface preparation.

According to Guhring, the result is a smoother cutting action, extended tool life, improved reliability and
consistency, as well as better thread quality and precision.

Pionex taps are manufactured from a powder steel compound that offers a high level of wear-resistance, while a TiCN surface treatment provides durability.

This combination of characteristics is complemented by a new Guhring polishing technique that makes the surface of the thread formers smoother than before.

With regard to geometry, the groove depth and width have both been increased to maximise lubrication at the point
of thread forming.

The Pionex series is available in all major thread types, including metric, metric fine, UNC, UNF and pipe thread. Guhring has also made the thread formers available with through-coolant capability.
