I suspect the first and last are single-lip reamers, but I'd have to
see it.
The second is just a repeat of one of your lathe bits.


Whups. End view, It would take a real pair to plunge with this one.

That one's got me. The lip looks like a reamer, but single-lip reamers
need a bearing surface opposite the cutting edge, like a gundrill. I
can't figure that one out.

Face groove or trepan, too long just to groove, so I suspect trepan

I don't get it. How do you trepan with a solid tool? Or am I misreading the
photo, and this thing is hollow?

For that matter, how would you face groove with this tool?
