On occasion, I need to cut aluminum stock, both 1.5" x 1.5" x 1/8"
angle stock and 1" x 1/4" flat stock.
I have always used one of those metal-cutting wheels in my 10" Delta
Miter Saw, similar to this:
The other day, I was watching "How It's Made" and they showed the
process used to make Carbide Tips saw blades. They started with the
raw steel and followed the process through to the final product.
At the end of the segment, they showed a carbide-tipped blade in a
miter saw cutting through a steel rod with the voice over saying
"And when they're finished, they're strong enough to cut through the
steel that they are made from."
Somehow, I'm reluctant to start using my carbide tipped blades to cut
my aluminum stock. The thought of the teeth grabbing the angle iron
just scares the bejesus out of me. But if they can be used to cut
steel, aluminum should be a breeze.
Am I right to be afraid, be very afraid?
Are the cutoff wheels, even with the melting and subsequent filing/
grinding that I have to put up with, still the best option?
