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
  • DIN / ANSI standards dimensions for flute length and shank size
  • GLT-1 coating - Hard surface coating with anti-friction layer. In a PVD process (500 °C) a coating thickness of 2-4 μm can be realized. The combination of a hard surface coating (approx. 3000 HV) with a superimposed anti-friction layer yields decisive tool life advantages. Also, the chip flow can be very positively influenced.
