I have a cheap-o tap and die set. Think it cost $50. I was poking around for something that could handle somewhat harder steel. Happened to see https://www.mscdirect.com/webapp/wcs/stores/servlet/product/details/43489657 and was taken a-back. Like $4000? It isn't often that one sees like 100 to 1 price variation for what seem to be comparable utilitarian tools. I guess 10:1, like for drill bit sets, I sort of see. Any thoughts as to why there is this sort of tap and die price dispersion. I mean, yes, they use better steel. And more precisely and American made. If I used one of those taps would I notice a difference in soft steel? Is it that the $4000 enables HRC 62 taping? For $4000 some machine shop is getting some serious utility. -Bill
