That is a lot of cutoff wheel cutting. After seeing on Myth Busters the exploding CD show I now have even more respect for a fragile wheel moving that fast, one half the mass velocity squared is not your friend.
If I did something like this with that much cutting I would like to water cool the blade every now and then. However, I would be concerned how the Dremel cutoff wheels would respond to any moisture.
Because a shovel like tool has a lower hardness value, does this mean that losing some is not that big a deal or because it was low to start with there is less room for error?
Not really either. It's still a big deal but there's still good room for error. If it gets uncomfortably hot to the touch dip it in some water for a few seconds. The cutoff wheel will still work fine if it gets a little damp, so no worries there. Just cut a little out from where you want it finished (about 1mm I'd say) so that you have a little wiggle room if you make a mistake, and when filing/grinding it to finish it out you're automatically going to go past any zone that might have been heat affected.
It's not as complex as some folks make it sound.
