Spiral Fluted Taps Intro AU+SP MP Multi Purpose Series SP Plus Series Spiral Fluted Taps, Coated DIN FEATURES Multi purpose for blind hole application on a wide 2.5P range of materials. High precision blanks and enhanced SL HSS-E COATING geometry allow top performance in term of thread THCHT accuracy and tool life. BLF geometry reduces edge chipping trouble and improves chip ejection. Recommended Tapping Speeds Depending On Materials Suitable coating improves wear, heat and welding PO resistance.

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.
