Default Metal Cutting Blade For Miter Saw

I have to cut some aluminum for a storm window and would like to do it on the miter saw as I would like a clean 45 degree cut. In the past I have cut aluminum with a jig saw or recip saw but this piece is only an inch wide and I want the cut clean and accurate. What blades do you folks recommend for miter saw metal cutting?
Thank You.

I cut thin (under a 1/4") aluminum on my miter saw with a miter saw blade. The rake on a miter saw teeth is not as aggressive as a regular cross cut blade. You can also try reversing any carbide tip saw blade if you do not have a miter saw blade.

Learning is an exciting adventure

I've also cut 1/8th aluminum bar using the 80 tooth Freud. Makes a very clean cut. Most blades will cut really thin aluminum stock, but I'd avoid one with a really aggressive rake to the teeth. You might want to back it with some scrap wood.

The more I do, the less I accomplish.

high tooth count triple chip in NEGATIVE rake is what you want...

I just wanted to say, it is really amazing to me the amount of knowledge that is available on this forum if you just ask. For me this so great, as old as I am, and just starting in the woodworking areas. I am impressed. I want to say thank you to all of those who are willing to impart with their knowledge in an attempt to help us less fortunate individuals.

Yep. If nothing else we can serve as a bad example. Meanwhile, the older and grumpier we get, the better stories we tell.

The best way to improve the human condition is to build a storehouse of knowledge and make it freely available.

Someone I consider a master woodworker once told me that a master woodworker is not someone who never makes mistakes. He is someone who is able to cover them up so that no one can tell.
