Product Features Good chips discharge

  • The AU+SL utilizing a left hand spiral flute to achieve stable chip discharge performance even at high spindle speed tapping.
  • Offers good chip discharge in a wide range of work materials from steel to stainless steel.
  • The laser marking has been moved to the square area of the shank to insure a fine surface on the shank diameter. Burrs can be generated and the precision of the shank can be impaired by placing the markings on the shank's diameter. To maintain the precision and the circularity of the finished shank diameter and maintain the high accuracy, the taps size and limits are now marked on the square portion of the tap.
  • The AU+SL is applicable to a wide range of work materials. It utilizes a flute shape that can maximize the features of the wear and heat resistance by coating. The coating offers an adhesion resistance, and can handle a wide range of work materials. It is also ideal for water soluble cutting fluids.
