I came across this tool in a drawer of a lathe I purchased from a school. It is a boring/threading tool I think. I've searched for cutting tool for it but had not luck. I thought it was a scrap of steel until I cleaned it up a little. Any help would be appreciated.

Yup, that's a boring bar. Looks like it takes 1/4 inch square bits.

Here are a couple that I have with the wrench that's used to lock the bit in.

They use normal square bits that you grind to whatever profile you need.

I measured it and ordered 3/16 tools for it. Thanks for the help......Harbor freight is close by but we just got buried here on Long Island and I'm not in a big rush.
