Thanks for the input everyone! Some of them do look like they've been tossed around, and some of them are in very good shape, from what I can tell (I've never used a reamer). For instance one of them was encased in some sort of soft plastic or hard wax that really preserved the cutting end quite well. At any rate, it brings up a good point, what's the proper way to store these? The machinist at work has them piled up in a drawer, but he doesn't buy them either.
A_Pmech - not a bad idea on the shadow box, but I have a bunch or other more interesting tools that I inherited that would serve that purpose better, these reamers don't hold too much sentimental value, although enough that I was compulsed to clean each one.
Ron - so if you look at picture DSC04406.JPG, it happens to show the only tapered reamer in the bunch, but does it chuck into a drill or is it for hand reaming? I ask because, there's a hole there on the shaft, and no markings as if it's been in a chuck before. At any rate, it's 11/16" shaft so wouldn't work for you.
I also have about 100 hex/allen wrenches that I inherited as well. What do you do with those!? A few are large, but geez, how many do you need!
