"What Is This Thing?" Running Thread

[scwhite]

This one has me puzzled. It was in one of the boxes of change gears and/or tooling that came with my lathe.

Reminds me of a hypodermic needle, but on an alarming scale.

It looks like a rubber drill

I bought a box of small stock at a groj sail a couple of months ago. To entice me to buy they threw in a box of...stuff. I was cleaning my shop today (read: Moving stuff from one place to another in the shed.) and decided to 'inventory' the items therein. Some dead centers, boring bars, scrap, job made parts etc. Ant then there was this.

It seems familiar and I'm almost positive I've seen something like this before but for the life of me I don't know what it is for.

It reminds me of a broken tap remover, however, I've only seen 3 and 4-flute versions.
You seem to have a 2-flute version.

Oh wait, they do have 2-flute versions:

Tap extractors

 

[T Bredehoft]

Tap extractor, I've got three or four of them, varying sizes, don't work very well, the pins bend/break too easily.

Thank You Brino, SCwhite and T Bredehoft. Now I know but I thought it was too big for something like that. I guess a big tap???

This looks to be an electrical connector tool. Older caterpillar equipment uses "sureseal" electrical connectors. The connector housing is a big thick chunk of formed rubber. Slide this tool into rubber, then slide wire with terminal that is crimped on into position, them slide tool out. I have something very similar on my work truck.

I got about 2 dozen of these in a box lot of various roll-pins, set-screws, socket-head cap screws, rivets, etc.
They look like some kind of insert or anchor nut, but I'm not sure how you'd mount them.
They are threaded #10-32 NF, and the square nut floats in the round disc.
I thought the outer pieced looked like aluminum, but it is steel (magnet test).
The OD passes thru a 15/32" hole.
They have small ridges on a shoulder, that I guess could go into a counter-bore to stop them spinning?!?

Any help is appreciated.
