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.

Product Features
CARBIDE BLF (thread portion of special design) + proprietary fl ute
design: Great improvement in chip ejection effi ciency.
AU+SP has a special thread portion design with thread crests
ground off and a few full threads after chamfer.
Eff ects 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

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.
