End Mills?

[Martin W]

I received a bunch of these, I believe are end mills. Or would you use them in a lathe tailstock?
Thanks

I'd call them drills, rather than end mills. They appear to be cemented (brazed) carbide cutting edges.

They look like hammer drill bits for cement or masonary.

They really don't look like any masonry bits I have seen. They were in a box of milling machine stuff. They do have brazed carbide cutting edges.
Thanks

They look like counterbore bits.

That's what I thought, but the square shoulders (that would be for the counterbore) appear to be the same diameter as the drill.

You may be right, Stan. I was going by the first and third picture. So that is my best guess. Mark

Probably made for a custom job. For a specialized turboencabulator part for certain.

I’ve got fishing weights that look just like that.
