I am running through tons of taps on a stainless job I have done in the past. Its 316L .187" dia.
I have tried 3 different kinds...Gold (TIN), Black (TICN), and HSS Black Ox/Bright finish.
I just put it on another machine and when I set it up I used a plug tap to get it where I wanted it. The tap had no reduced shank but the chips were packed in the part (as it should).
As soon as I went to the Gold tap I snapped 3 in 5 parts. These taps had the smallest shank on it. They all broke on the way in, towards the bottom.
I am having a hard time finding a good source for full thickness shank taps in the smaller sizes (Spiral Flute, Bottom).
I ran 5k of these with 3 taps last time I ran it. I was at first getting 300ish parts per tap. Is that normal? was I just lucky for some reason I made 4k parts on 2 taps?
Thanks in advance.
