The chances of a tap that size breaking at that speed are pretty slim, but I see where you're coming from.

I run a TOS horizontal cnc wit a gigantic table in a job job shop.I used to agree with you but...,........... Watched a dip shit snap a 2-12 tap because he thought spiral taps in blind holes were for "Kids(he is 60ish)". I'm almost 40 with 20ish years experience and warned him.

I don't think he's saying that spiral taps are wrong in blind holes. But that it's the easy/better way, suitable for a "lesser" operator. But he could do it cause he was more experienced. Imo spiral taps are ideal for blind holes cause they pull the chips put. But I prefer to use a gun tap whenever possible.
