dremel with cut off wheel

I don't know how they do it, but they've had aluminum gutters and
downspouts for 50+ years and I doubt many people, I don't anyone used
a dremel.

Tin snips or a hack saw with a fresh blade.

Snips pretty tough to start on downspout.

32 tpi hacksaw blade for the homeowner pretty much the "tool of the
trade" but pro's often will use a chop saw w/ 24 or thereabouts carbide
tip blade. I've used a 12" blade in the Sawzall but you can't be timid
in the approach; _must_ get the foot on the spout surface to keep it
from catching and collapsing it. I've not set one up for it, but I'd
think the sawzall in a vertical position w/ a table would work pretty
well if were doing a bunch.

But, w/ Al, it's so soft and easy to cut, may'st well just use the
hacksaw and go on...

A couple of my co workers just use the an oxygen-acetylene torch
to cut aluminum pipe to install flow meters. I don't think they hit
the O2 but don't know for sure. They say it's better than a sawzall.
It's usually 8' pipe with about a 4" diameter hole.
