螺纹铣刀切削为粉末状短屑，不易缠刀，丝攻加工为螺旋状铁屑，容易缠刀。
螺纹铣刀非全齿接触切削，机床负载和切削力都比丝攻小。
装夹简单，丝攻需要柔性攻丝刀柄，螺纹铣刀可用ER.HSK.液压.热涨等刀柄。
加工高硬度螺纹时，丝攻磨损严重，甚至无法加工，螺纹铣刀则可轻松完成。
采用斜式多排、屑槽设计，高精度螺纹，多排屑斜式多排屑槽，螺旋散热设计，铣牙排屑顺畅，光滑无毛刺。
The thread milling cutter is cutas powder short chips, which is not easy to wrap the knife, and thethread tapping is processed as spiral iron chips, which is easy towrap the knife.
The thread milling cutter is notfull-tooth contact cutting, and the machine load and cutting forceare smaller than the tap.
The clamping is simple, the tapneeds a flexible tap handle, and the thread milling cutter can beused ER.HSK. Hydraulic pressure. Heat expansion,etc.
When machining high hardnessthreads, the tap is seriously worn and even cannot be processed,and the thread milling cutter can be easilycompleted.
Adopt inclined multi-row, chipgroove design, high precision thread, multi-row chip inclinedmulti-row chip groove, spiral heat dissipation design, millingteeth chip removal smooth, smooth without burrs.
