I should have mentioned an up-spiral bit. that will pull the chips
up.

And in an effort to keep it on topic....


If you chose to use compressed air, the dust will be pronounced.
Using a vacuum would offer some additonal chip removal, but typically
only after it exits the hole unless the vac is very close to the work.

If you are only cutting sheet, considder a vacuum that shrouds the
cutting tip and is as close and as small as you can get.

The closer it is to the work, the more it forces air into the cut
pathway.
