Can anyone identify these?
They are made by Van Norman, have a straight-keyed shaft bore same as a milling cutter.
The black part is a hard rubber/plastic composite of some sort.

Van Norman also makes automotive service equipment. I am going to say they are part of a brake lathe setup. Centralizers or some such. They wouldn't be cutters with plastic/rubber support for those segments.
 
The material is not flexible, it is very hard/stiff and the cutters don't move, but it is some kind of composite around a metal hub. The metal edges are all sharpened in a beveled cutting fashion, with a leading edge that is sharp enough to at least scrape away material, and the keyed center bore tells me they are meant to be spun.
The style of the wooden box they came in makes me think they are at least from at least the 1960-70's. It has square dovetailed corners like an old cigar box.
There is are no readable markings on the box.
The diameters are from about 2.25" on the smallest side of the smallest one to about 5.25" on the widest of the wide one.

When I worked at a car dealership years ago, our brake lathe machine did not have anything like that! I doubt that they are cutters, look more like a collet of some sort.
 
On checking the new Van Norman site which is now Kwikway I wonder if they are arbour adapters that have vibration dampening as well?
 
I don't believe they are collets. The segments do not reach the bore, for one thing. Collets are generally the same OD with different ID's. Since these have keyways, they are a driven member of some tool. I don't think they are cutters either. The plastic/rubber holding the "blades" or segments would hardly be strong enough to cut anything.

I know that newer brake discs and drums require a whole different approach to machining than the older ones. Especially the composite rotors. I made a cousin who owns a shop a set of dampers for his AMMCO brake lathe, but they weren't anything like these, whatever they are.

I guess you could send a pic to Van Norman (Kwikway) and see if they will ID them. I'm curious, for one. :)

Possibly for some type of wood working operation?
That almost looks like sawdust on the close up of the one "cone".

I have a number of barrel bedding tools that have similar blades mounted in a stiff rubber damper that shave out wood quite nicely.
Just a SWAG.... ;)

To champher big end bearings?
They'reobviously made to remove material from something soft.
