Enorm Z Taps


The Enorm design is typically for blind hole threads in long chipping materials.

  • The fast spiral flute (35-50˚) provides good chip removal from blind holes
  • Depending on design and size, threads up to 3xD can be cut
  • Z designates a tool design for CNC controlled machines with synchronous feed control
  • Short Form E (1.5-2 P) chamfer length
  • ANSI / ANSI standards dimensions for flute length and shank size
  • Manufactured to produce 3B tolerance thread forms
  • Bright surface finished options
  • TIN Coated - Titanium-nitride. In a PVD process (500 °C) a coating thickness of 1-4 μm can be realized. The hardness of approx. 2300 HV, the good sliding properties and coating adhesion guarantee long tool life.
