I tried a hole saw in my cheap drill press. Works perfectly for
hardwood, but doesn't work for 6061 aluminum. I might try removing
some teeth from a hole saw, see if it cuts a little better without
the chatter. I am familiar with inwards and outwards leaning
teeth.
Will I have better luck with a 40mm carbide cutter that has fewer
teeth and maybe better chip removal? The hole diameter must be
near perfect, so I might end up buying more than one (different
versions) of those if it cuts through the material.
Is there a small machine made for cutting shallow holes in metal?
I suppose a good drill press would work, but only if necessary.
I recently purchased DeWalt's small cordless metal cutting bandsaw
and think it's great for cutting most small/narrow aluminum.
I really want to cut that hole.
This will do the job.

BWAAAHAHAHAHAAA!!!
Looks like that type has a special shank.
I will try using ordinary carbide cutters and maybe a more robust
looking hole saw, possibly after cutting a few teeth off.
