Recently had to tap a 5/16-18UN blind hole and all I had was a spiral point tap. Of course it worked, but I would have felt better if that wasn't one of the few remaining sizes in which I don't yet own a spiral flute style for blind holes.
I fixed that on eBay for $6.80, shipped. What a bargain. List price, $24.90 US.
