Hmm. How do you hold the angle grinder so that it doesn't shift?
I am not strong enough to hold even a drill motionless with a single
hand, so I put a foot on it.

I put it on its back and hold with one hand. I expect you could use a
foot, but I wouldnt be confident doing that. You might also use a
bench vise with a rubber wrap or an angle grinder stand.

I am not strong enough in the wrist to do that reliably, and a bench
vice brings in the space problems.

also drill wood far better due to changing the original angles, which
are good for steel but quite wrong for wood. A cutting disc is used to
get into the flutes, grinding discs being far too big.

Yes, but this can also be done with a simple grinding wheel or bench
grinder. You can also clean the flute by using the bit (that's an
ancient trick, predating angle grinders).

I dont see how either of those would get far eough into the flute to
grind away most of the solid centre section where it meets the tip.
Even a grinding disc in an angle grinder cant do that.

Oh, right - but that's much more than just changing the angles and
cleaning off the burrs - it's changing the shape of the point. No,
I don't do that.
