Anyone know what kind of bit this is? Acquired it from a friend and tried looking up the numbers and company but I got nothing!

Looks like a “Star Bit” for drilling concrete. Impact, not rotary action.
Well used.

I know the person who had it used a metal lathe so I thought it was somewhere along those lines

It is a metal ream, designed to fit in a morse taper socket. It won’t last too long in a concrete application as its intent is to provide a very precise diameter in a blind or through hole.

I was going to say some kind of ream, but yeti beat me to it.

It’s a reamer the size should be on the shank. It’s for making a hole an exact size after it’s been bored. Using one on a large hand held drill is not a fun job. But the steel they are made makes good knives.

What size is it? I do a fair amount of turning on the lathe and could always use one more reamer.

This is actually reamer for making very exact holes in metal. I don’t think it is sharp enough for boring/reaming wood.

I’m sure the previous replies have already nailed what this piece is, but I noticed during disassembly of my drill press, that the star-shaped end showed up. I think it’s the gear that turns the quill shaft.
