I purchase as much of my tooling as I can from auctions and Craigslist. Occasionally in lots, I'll get items that I don't know what they are or the application that they're used in.

I'd appreciate some help with these items. The 1st 2 pics are some reamers. They're tapered and have morse tapers. What application are they use in?

The next 3 pics are of some carbide tool bits. What are they used for? An example would be useful.
