The sucker isn't cutting aluminum.

Trying to cut a square aluminum tube about 1 1/2 inches with 1/16
inch
thick walls. The thing is pressing the wall down more than it is
cutting. The disc is slightly warped, too.

The arbor hole is not keyed, it's perfectly round. Is that so that
the
10" aluminum oxide cutoff wheel might slide instead of
shatter/break on
startup?

By the way... Do all miter saws start abruptly? Mainly curious.

Thanks.

A saw blade for wood cuts aluminum just fine, if noisily. You don't
need an abrasive blade, which may be loading up.

I resized an aluminum storm door and its glass and screened inserts
smaller with a wood-cutting bandsaw.
