SG Spiral Tap
It is hard to be broken by high rigidity flute shape design
Sectional shape
Comparison of the breaking torsion torque
The breaking torque of SGSP is 30% bigger than competitor, SGSP hardly breaks
SG Spiral Tap is that the width of land is wide, and the cross section is large.
Rigidity of stress concentration part is high, the breaking torque is big, so hardly breaks.
Cross section structure of SG coating
SG coating is dense quality film for specific use of tap
Improve wear resistance and toughness by using fine multilayer film
