Steel 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
  • Form C (2-3 P) chamfer length
  • DIN / ANSI standards dimensions on overall length and shank size
  • Enorm 1 design will have a reinforced shank design
  • Enorm 2 design will have a reduced shank design
  • Taps are manufactured to produce a 3B class of fit tolerance
