P series cold forming taps are especially designed for higher performance compared to our standard A series
forming taps.

With cold forming taps the thread is obtained by plastic deformation instead of material removal. The main
advantages are a higher tensile strength of the thread due to work-hardening, no need for chip removal or
evacuation and the possibility to thread both blind and through holes with the same tap.
The main limits concern the workpiece material which must have a minimum elongation coefficient of 10% and
a maximum resistance of 1200 N/mm2. Another important requirement is a larger and more precise drilled hole
diameter compared to cutting taps, in order to obtain threads with the required tolerance class.

P series high performance cold forming taps are made in powder metallurgy high speed steel, HSSK, which
confers excellent wear resistance. Furthermore, the BP versions are equipted with an internal lubricant channel
with axial outlet for blind holes and radial outlet for blind holes or through holes.
