What do these fit? What are they?

[RodP]

I'm assuming these are some type of cutter for maybe a milling machine, not sure. I placed a bid on an online auction, the lot had lots of odds and ends of different tools. I only bid $7 and figured I'd get out bid. Well, I'm now the proud owner of about 20 of these cutters in different sizes, if that is what they are. Most are in plastic tubes, some are just loose with wax protecting the cutting flutes. There were also some drill bits with the same type of chuck end on them. I'm not a machinist and know very little about this stuff. I hate to throw them away, but I don't need more clutter in my shop. If I knew for sure what they are and what they fit, I might have a better idea of who might need or use them. I did get way more then $7 worth of tools in the rest of the lot however.

If you are someone who could use these and willing to pay the shipping cost, you can have them.

Thanks for any help!

From left to right...Drill bit, drill bit, then all reamers. No clue who the specialized mounting system is for. #4 and #6 are commonly known as "chucking reamers", with #6 being a piloted style.

Old style post drills would use a 1/2 shank in all drill sizes. Set screw held them in.

I suspect your drill bits are to fit a machine setup, where a Jacobs adjustable chuck wasnt used, just a fixed diameter locking system. Usually on line drills, where multiple holes are drilled close together in the X Axis.
