Did an impulse purchase of a basic set of carbide burs on Amazon, before I the post on special aluminum burs that had coarser flutes. I did follow the Sutton Tools link. But they redirected me to the North American site, which did not have the aluminum burs. I'll see how the finer cut amazon burs do, then order 1 cylindrical aluminum bur.

Thanks guys for the replies. I can always count on weldingtipsandtricks.com to bail me out.

They'll be out there somewhere. I like to google search images, and then back track to a website once you have found a picture of what you want

Before I used the right stone for doing aluminum i would get it to the point it is in the picture then use a old file or something sharp and dress off the built up aluminum.

Soak the stone in ammonia to remove the aluminum. Old slivers of bar soap work great to keep the aluminum from loading too bad. Better than wax even. Works on burrs too. Soap is a salt of fatty acids and sodium so it is aggressive to aluminum plus it has a higher melting point.

True. And I'll point out that Dial and Dove are NOT "soap", they're detergents. Ivory is soap.

Actual soap will say, "soap", while Dial, Irish Spring, Lever 2000, et. al. will say "bath bar" or some other nonsense.

While we are on the subject of soaps (and bars of chemicals) smear it on your wood screws to make screwing them in a bazillion times easier

I use bee's wax for screws. Never thought about putting it on my stones for aluminum. But I'll probably try it now.
I have more questions than answers

At work we use Boelube on all of our abrasives for aluminum and all aluminum drill bits and burrs. It's hard at first but melts as the tools heat up. You can also apply it to the surface.

That is good stuff, we used that also for tapping.
