Alloy with high speed steel tap tap is not the same, high-speed steel cone concentricity requirements are not so high, Alloy Tap processing concentricity must be good, just a little off may be slightly crooked, speed must be slow, even the best production of tungsten alloy tap, there is no way to guarantee that will not break, this has nothing to do with the quality of.
