I bought a box with a few small engineering tools in at a boot sale on Sunday and in was this gauge for screwcutting tools.
I have the rectangular ones for grinding and then setting tools in a lathe, but never seen a round one.
So, can anyone enlighten me why is it has the round hole and 'keyway' and is it just for grinding tools?
