Product Features

  • Improved tool rigidity from new blank shape that offers torsional strength and shank accuracy.
  • Markings that were on the shanks outside diameter have been transferred to the square part to improve circularity.
  • New thread portion offers improvements in the accuracy of the "GS" class of internal thread tapping.
