Product features Smooth chip ejection

  • Special left hand spiral flute design enables the smooth chip ejection even in high speed tapping area.
  • AU+SL ensures the smooth chip ejection in the wide range of work materials from steels to stainless steels.
  • Change of marking position from shank into square portion:

Laser marking can roughen the shank surface. In order to keep high

accuracy of shank circularity and diameter, marking has been transferred

from shank to square portion.

  • AU+SL adopts a special flute design enabling coating features to show their best efficiency, and is applicable to the wide range of work materials. AU+SL also runs well even in water soluble cutting oil.
