Product Features
Smooth chip ejection Special left hand spiral fl ute design enables the smooth chip ejection even in high speed tapping area, on a wide range of work materials.
Change of marking position from shank into square portion EG (STI) 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.
