AU+SP has a special thread portion design with thread crests ground off and a few full threads after chamfer. Effects of AU+SP are as follows: LONG - Prevention of chipping trouble at full thread portion - Reduction of tapping torque and tapping friction - Good chip ejection HAND TAPS 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.
