That is an interesting question. Diamond is used to machine aluminum in the
manufacturing world but I am not sure how the blade you describe would work.
I'd just buy a carbide blade since it works great. Go to Home Depot or the
other home improvement stores and look for a carbide tipped blade for
cordless circular saws. By the way how many rpm does this saw turn?

I haven't been able to find a 6" carbide blade with a 5/8" or 7/8"
arbor. I'm still looking, though. (The saw turns at 9000 RPM.)

As long as you are careful feeding the saw blade into the cut, a coarse
blade will be fine in this application.

Good to know, thanks.
