I have a 10 inch miter saw that will handle some Kwik Frame extruded aluminum pieces. What type of blade will give me a fine cut? Extruded aluminum, being pricey as it is, I want to get it right the first time.
Blade for cutting extruded aluminum?

Typically I just use a high tooth count carbide "wood" blade.
What's the extrusion look like? Some can be grabby

We cut a bunch of extruded alum with a Diablo alum blade; works really well. Don't cut super fast. I bought 4 blades thinking we'd burn through them, only used one for about 25 threasholds.
Might be worth buying a blade:

But again, I use my finish wood blade all the time for a few cuts. Keep the open side of the extrusion down to avoid the teeth grabbing, and feed the saw slow and consistently.
Wear ear/eye protection.

Hold the piece securely and feed the blade slowly. Clean up the edges with a razor knife. If you really need to, let the blade stop before coming out of the cut.

The guys next door to me at my business were cutting a bunch of aluminum light fixtures on a table saw last week. I remember he said they found a blade that really worked well. Ill ask them in the morning and see what it was.

I've cut quite a lot of aluminum repairing tractor trailers with just a Diablo Demo Demon in a hand held circular saw and it worked very well. They arent that expensive either.
eeek!I picked up this today at Harbor Freight. It should work fine for me. $40
Not sure I'd spend $40 in a blade at HF.

I forgot to post earlier. My guys next door said they got a Diablo blade that said it was for Aluminum. Not sure what sizes it is available in:

On painted material, the paint can act like a lubricant. For mill finish or anodized material we try and run coolant as it helps with cut quality, blade life and noise. Shoot a bit of WD-40 on it and see if it makes an improvement

Definitely use wd40 liberally. It really works. I've cut up to 3/4" aluminum plate on a table saw with it. As well as thin wall extrusions. And miles of aluminum soffit. Table saw and miter saw both.
