(m/min) 45〜55HRC Product Features

  • Ideal for hiIgh hardness steel blind hole tapping of 45 to 55 HRC materials such as steel for hot dies (SKS 3, SKD 11, etc.).
  • The EH-CT utilizes a ultra fine grain cemented carbide that is superior in abrasion resistance and impact resistance.
  • Improved run-out accuracy of whole tap and circularity of shank.
  • Tapping length is the "major diameter size × 1.5 or less", 5P chamfer for better tool life.
  • For the bored hole diameter, the maximum minor diameter of a 6H internal thread diameter maximum value is recommended.
