I have been finally getting to various project. Discovered today that
the very neat double spiral 7/16 auger bit is ... bent. I'm not sure
how much out of round, but if I roll the twist, the tang at the end of
the shank is rotating in a circle much larger than the diameter of the
hole. Not good, tends to cause the entrance hole to "ream out" and
become over size.

So, any suggestions on getting it back into straightness?

you find out it's a 900lb gorilla with a flashlight!!

Typically, auger bits are spring tempered, and so can be straightened
by bending using an arbor press and some V-blocks, but it's a bit
fiddly.

One has to overbend slightly, see how close to straight it now is, and
repeat, rotating the auger in the V-blocks as needed. It need not be
perfect to be perfectly useable.

Machine shops can do this, and are usually pretty practiced at such
things.

Well, of course it is a bit fiddly ...

I have access to Maker Space - maybe I can do it there.

That could work. You will also need clamps on the V-blocks, to
prevent undesired rotation of the auger bit while it is being bent
back to straight.

Let me check my tool box ... (I use to be a machinist. Kind of
hard to do that in a 2 bedroom apartment.)

Well, V-blocks don't take *that* much space. Maybe stout wooden (oak
or maple?) V-blocks would do for banding an auger.
