Box 1 are sets for pneumatic or manual rivet squeezer. About 30-50$, depending on quantity there.
Box 2 are threaded drill bits, various sizes and A, B and C lengths. 10$ maybe...all are well used.
Photo 3 shows blind hole duplicator straps. Maybe 5-7$ each
Photos 4 & 5 are microstop countersink cages with piloted countersink cutters. Cages are worth 20$ each, if not beat up, shafts are straight and bearings are not worn and full of ****.

Hand squeezer and extra yoke, pop rivet tool, more sets and a flanger/seaming tool. 2nd photo is a an air vacuum and a Cherry riveter....There are a number of versions of this tool, so it would take some detective work to determine the exact tool configuration, and which rivets or lockbolts it's for.

Always wondered what the purpose of threaded drill bits are, i get that they wouldn’t slip in the chuck but regular bits are good enough for a drill press, and I’d much rather it slip than grab and throw the workpiece at you or break your wrist in a hand drill, and they must be a major pain in the *** to get out if much force gets put on them
obviously they’ve been around a long time and are still made so must be something I’m missing no?

if I had to guess I bet they allow for a very small 'chuck' and are easy to get in to tight places.

Are some of the threaded ones left handed? Line boring machines, which don't seem to fit the rest.

Since you have a Yardstore box, I’d go to their site. Should have all that if aircraft skin stuff.
Have some hide your credit card tho, lots of cool stuff you will think you need.

Looks like you struck sheet-metal-fabrication gold! Dimpling dies, hand and pneumatic squeezers, hole-finders, air operated vacuum cleaner, threaded drill bits for a right-angle drill, and countersinking stuff.

The threaded bits are typically used in a right angle or angled drill, or pancake adapter, for drilling in tight location where a standard drill will not fit. I've never have seen a left hand threaded bit, as they would unscrew from the tool under load.

Zephurtoolgroup.com is the place to look those up as most of those bits are still available. The microstop countersink I bought used over 50 years ago, I still use when I need an accurate countersink. Those are available on Ebay searching for aircraft tools.

The threaded drill bits are for drill attachments that are used for right angle drilling. Not a tool I use often but it comes in very handy in certain situations. Aircraft Tools Inc. and Geo. A. terry Co. are two manufactures of these drill attachments.

Looks like about a quarter the contents of the top drawer of my sheet metal box
