螺旋丝攻系列
螺旋丝攻对在盲孔内攻牙，切屑连续排出的钢铁材质效果良好。因为约35°之右旋蜗槽切屑可从孔内向外排出，切削速度可较直槽丝攻加快30-50％，盲孔
之高速攻牙效果良好因排屑顺利。对铸铁等切屑成粉末状的材料效果差。

Screw tap series
Screw tap in the blind hole tapping, chip continuous discharge of steel material effect is good. Because about 35 °
of the right hand worm groove chip from the hole introverted effluent out, cutting speed can be a straight
flute silk attack speed up 30-50%, blind hole of high speed tapping effect is good for clearance smoothly.
For cast iron, and other chip into powder material effect is poor.
