Designed to increase performance in tough steels & exotic metals


  • Engineered for versatility with special rake angles and relief so taps run with less vibration and can achieve higher feed rates.


Hard Steel
  • Specially designed for materials from 240 BHN (Brinell Hardness Number) to 350 BHN.
  • Rake angle and relief are adapted to provide higher productivity.
  • Improved the toughness of the tap.
Stainless Steel
  • Unique geometry and the surface treatment minimizes microweldings on tap flanks.
  • Eliminates chipping risks.
  • Keeps the right tolerances much longer.


  • Provides higher performance in tough alloy steels, stainless steels and high strength thermal resistant materials and gives superior wear resistance.
  • Designed to increase productivity and longer tool life.
  • Excellent for CNC machining.
