Need some ID information

[Gary]

Tell me what I have? Bought these on a box deal off *bay. All for $10 plus shipping. I bid because of the smaller reamers but I don't have much of an idea about the large stuff. 2~3 drills, but the rest are cutters for a large mill of sorts is my guess. I don't have any collets that will hold any of the larger items and I'm not sure they have any value to a machinist. Again, let me know what I have. Thanks

Gary, I see 10 hand expanding reamers total; 5 smaller ones in the first pic and 5 in the second pic. Square on the shank is to accommodate a tap handle. You'll notice flats on the small threaded portion on the end opposite the shank. That's where you use a wrench to adjust the dia. of the center-blade section.

I also see what appears to be one, maybe two end expanding reamers in second pic. Should be an allen in the end. Screw it in, the reamer flutes are forced outward (dia. expands).

First pic there are two straight flute hand taper reamers (small and larger) small one has had a piece of round stock added to lengthen the shank, and a helical flute hand taper reamer that has also had a round shank extension welded on to it.
Fourth from left, no clue.
Sixth from left looks to be a shank that is supposed to have maybe an interchangeable cutter mounted on it.
Seventh from left looks like maybe a small line-reamer that's had an extension welded onto the shank.

Second pic (far right) has what appears to be a spot-facer (counter bore) that's had the end ground into a pilot. Next to it is a standard chucking reamer. Second from left appears to be a spot-facer that's had a shank extension attached to it.

Wow, thanks for the detailed info. Now to figure what they might be worth to a fella down the road that has a couple of large Bridgeport Mills, Lathe, ect. His shop happens to be where I get most of my flat bar stuff.

If the hand expansion reamers need resharpening, they have little, if any value. End expanding reamers are comparatively easy to sharpen and will have at least some value. The chucking reamer, the end expanding reamer(s) and the drill bits likely have the most value.
There is a type of hand expansion reamer that uses replaceable flutes (blades). The blades or flutes are usually made of Stellite, which is a high speed alloyed with cobalt. Even if the reamer is useless, the blades can be reground into small boring or turning tools.

All good info; my plan is to trade these for some steel to use on my Mill.

Fourth from the left in the first photo looks like a wood lathe gouge minus the handle.

Actually it's flat on that surface and reminds me of a boring tool.
