The most effective way to cut CD's is with more diamonds. There are grit edged bandsaw blades available, but they're fairly expensive, and if one breaks prematurely due to metal fatigue, you're out a couple of hundred bucks. I like a grit edged lapidary blade myself, with a gravity feed. It's a little slower, but a good quality blade will last quite a while and is far more cost effective.

For most irons, a good bimetal blade with a low tooth count is sufficient.

This is a 12 pound individual that i cut in half a few months back. One half of the cut face displays a nice widmanstatten pattern, the other half is highly included with a muddy, shocked pattern.

some have a perfect Widmanstatten pattern, and some are altered, with
the pattern still present.
This one was deeply etched in an attempt to
pull out a pattern, but it just wasn't there.
Except for the bright bands, the surface
of this 66g piece was quite grainy.
