I'm doing a railing project and was looking for a Non-Ferrous blade for
my 10" miter saw, but Lowes and Home Depot don't appear to have them in
the stores. I want it for the weekend, so don't want to have to order
online. I only have six cuts to make in a powder coated extruded
aluminum top rail if all is good, so also don't want to spend a bunch.
What is special about about a blade to make it good for non-ferrous
metals like aluminum? Since I only have a few cuts, can I get a clean
edge from a cheap regular 10" blade? Are more teeth better? Four of the
cuts will be mitered corners, so I want them to be clean. This will not
be long term production, so durability is not a concern.
I was considering going to look at Harbor Freight. They have the two
blades below that may be at my local store.

or

I also have an abrasive metal cutting blade I used on 3/16" steel, but
assume that will not give me a clean cut.
I have a little extra length in the top rail segments, so will make a
test cut first.
Thanks for any recommendations,
Brian
