One question. Why did you buy an over/under set instead of an over/nominal or under/nominal or over/under/nominal set? It just strikes me that any one of those will just end up spending a lot of money for something that will rarely get used. I know, buying individually will prolly be even more before the war is over, but at least I get exactly what I want that way..... On the other hand, I see you already had a nominal set. Is that why?
Previously, I'd collected a number of reamers via auction box lots. Mostly onsize Imperial reamers but a couple of over and unders mixed in. But then,
@gerritv gave me an insanely good deal on the over/under set. If I hadn't stumbled into that, I would probably just have bought specific sizes when I had a need. In fact, recently I wanted to press an oilite bushing into something and bought a 0.749 reamer just for that purpose. The set only goes up to 0.501 inches.
Incidentally, I don't think I've ever seen a set offered that was just over-size reamers or just under-size reamers. If it is a set, it seems to be both the overs and unders.
I think the over/under set will actually be useful for me, though. OTOH, I'm sure there will be specific sizes I'll never use. Which is kind of like letter and number drills. There are 87 drills between those two sets and I'm sure I've only ever drilled with a handful since they were the recommended tap drill size. In fact, I've probably used more of them as a poor man's gauge pin set. I'll look for the best fit I can find using the shanks of the drills and then measure with a micrometer.
I see that places like MachineShopDiscountSupply have an over/under set available for 'just' USD $106:

Just throwing that out there since we like to spend other people's money!
