The ones on the left look like countersink bits, I could be wrong.

 

[Coach James]

One of the ones on the left looks like a plug cutter and I agree with 930 about the countersinks.

I'm thinking more like deburing tools on both sides, and the ones on the left go to the ones on the right (Guides).

They're Micro-Stop countersinks.

Maybe an aircraft mfg application - I see these is those kind of tool lots from time to time.

Countersinks and countersink cages.

The countersink cage is designed to stop the countersink at a pre-set depth to fit a countersunk rivet.

I don't need these so they will go in the class. Whats a used price on these?

Those are great countersinks, I have had some for 40 years that still cut great. If you do any work with countersunk screws you need to keep them. Zephyr is the biggest mfg of them and they are used usually at aircraft construction work. As they indicate off the top of the work the countersink is exactly right each time. They work just as well in wood or metal.

Those are a much older model than I am used to seeing, I'd be happy to throw those away for you, for the price of shipping.

These are micro-stop countersink cages and piloted countersinks. People who build or repair airplanes use them to accurately cut the countersinks for flat-topped rivets, so they do not stick out above the skin of the aircraft.

The heavy duty countersink cages go for about $40 each new (newer style). The bits go for about $6 each new. I see most people on eBay trying to get near-new prices for them...so I've been planning to go ahead and get them new. I probably wouldn't be willing to pay more than $50 for the lot. They look pretty rough and it's hard to see how sharp the bits are.

I see most people on eBay trying to get near-new prices for them...so I've been planning to go ahead and get them new. I think you could probably easily ask $100 as a lot ($20 for each countersink cage and $40 for all the countersinks). The folks who use these like to keep more than one, so they can keep it set up for the size of rivet they use.

One site has the 1/4" shanked ones for $15 new. http://www.panamericantool.com/micro-stop-countersinks-cage.html

This site has a complete set in a case for $205 http://www.spenro.com/microstop-countersink-cutter-p-491.html

Here's a site showing the Model #'s www.newmantools.com/severance/ToolCatalogstopcountersink_nt.pdf

I'd venture to say that if you cleaned them up, you could possibly get $50 depending on how many different size pilots and angle of the c'sinks.

Those are piloted counterbores. The pilot on the counterbore will fit the hole that is drilled in a piece of stock, then the counterbore opens that hole up to size at a certain depth. For instance, you would use one of those for a socket head cap screw if you want the top of the head flush with the surface of whatever material you are using. Two of those shown are just missing the pilots which are interchangeable.
