Better performance, in terms of tool life, is the main difference between the new P series taps and standard
taps.

The main features of P series taps are:

• powder metallurgy high speed steel, HSSZ. This steel is an excellent substrate for advanced coatings and
  allows high performance and productivity
• advanced PVD coatings, which improve wear resistance, reduce the friction coefficient between the tap
  cutting edge and workpiece and protect the tool from oxidation at high temperatures
• specifically designed geometry to improve chip evacuation and to reduce loads on the cutting edge:
  • for tapping through holes, the flute and spiral point profile has been modified, compared to standard taps,
    in order to improve chip movement in the direction of the tap feed
  • on spiral taps, the high helix angle at 45° allows deep blind holes to be threaded
  • on spiral taps, back tapering on the thread improves chip removal and reduces torque during inversion
    of the tap
• wide range of materials are machinable.

P series taps are available with straight flutes and spiral point, for tapping of blind holes, and with spiral flutes for blind holes, including taps with short chamfer form E.
