螺旋絲攻系列
螺旋絲攻對在盲孔內攻牙,切屑連續排出的鋼鐵材質效果良好。因為約35°之右旋蝸槽切屑可從孔內向外排出,切削速度可較直槽絲攻加快30-50%,盲孔 之高速攻牙效果良好因排屑順利。對鑄鐵等切屑成粉末狀的材料效果差。
一般用螺旋絲攻
漲大徑用螺旋絲攻
不銹鋼用螺旋絲攻
深孔用螺旋絲攻
鍍鈦處理螺旋絲攻
氧化處理螺旋絲攻
鋁專用螺旋絲攻

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.
