SG Spiral Taps

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 Taps have wide width of land, and large cross section.

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
