Nachi
Nachi SG Spiral Taps
Manufacturer: Nachi-fujikoshi corp
Model: SG Spiral
Features
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
Performance
No matter what cutting speeds. stable cutting screw threads and long tool life
