So I was given a box of random stuff by a guy that included an Amflo coolant mister and these grinding wheels. I can definitely use the mister but I'm not sure what these grinding wheels are for. I'm guessing some type of sharpening/honing machine?

I have several of these Continental Diamond Tool Corporation wheels. 6" diameter. The cutting edge comes to a 30 degree point. I was able to decode the label using the ordering info on their web site (type of bond, depth of diamond section, etc.) but I'm still not sure what they're for. They gotta be worth a little something, yes?

I also have this guy, which I was able to track down by the markings.

And a few of these, which are marked "WOLLF". They're 5" diameter. The weird thing is I can find "WOLFF" grinding wheels online but no "WOLLF." The grit surface is super fine.

Reads "WOLLF 39168/2 0399 015 BMR C50"

Also a few of these. Not sure what they're made of. Ceramic? 6" diameter. The used ones I have are used on the large flat side. For honing?

Any insight would be appreciated!
 
The Gator one is used on an Accu-Finish machine.

My guess is that the pointed diamond wheels are for cutting crystal or glass?

Sorry, I'm probably doing something wrong. They're in an album hosted here. Try this a different way:
