What are these things?

The edges are spiral like threads. I have something much larger like them that attaches to a cordless drill for splitting kindling, but I’m pretty sure that’s not what these were meant for! Biggest one is about 3/4” dia. X 4” long.

Love how helpful folks here are, thanks!

Look like mandrels for cylindrical or conical sanding drums. Typically used in die grinders.
