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.
