Product features

BLF（thread portion of special design） + proprietary flute design : Great improvement in chip ejection efficiency. ●AU+SP has a special thread portion design with thread crests ground off and a few full threads after chamfer left unchanged. ●Effects of AU+SP are as follows:

  • Prevention of chipping trouble at full thread portion
  • Reduction of tapping torque and tapping friction Chip ejection

・Good chip ejection

no trouble

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.

For wide range of materials

Adopting the flute of special design which enables the coating (features: wear resistance, heat resistance, and welding resistance) to work most efficiently, AU+SP is suitable for the wide range of materials and is well applicable under water soluble oil.
