They're made for cutting plastic! ;-) That's what's written on the
package. I just noticed they were made of carbon-type material and
figured I could carefully cut through metals ... which has proven to
be true .... going slowly. I imagine that cutting the aluminum angled
pieces I have left in this project, will be comparatively like going
through butter.

Dremel EZ Lock (EZ476)
It is a "package" of 5 and comes with the EZ Lock device that lets you
pull a small spring-loaded barrel, which releases outward pressure on
the disc, rotate/remove the disc, put a new one in, release the barrel
and you're ready to go again. The disc goes onto the barrel, is
twisted 90 degrees and has some small notches that the barrel snaps
into when it's released. Outward pressure from the barrel holds the
disc in place. My guess is that if you tried overworking this on
steel, it would twist the disc off of the center metal attachment it
comes with. I went through 2 of these on this project. 1 1/2" discs.
They are carbon .... look liker a high priced bicycle frame material,
minus the polished finish. The label on the package that the shop
(hobby/model-building) shows DREEZ476 on it. $10.75 for the 5 + the EZ
Lock tool/device.

Ya, I was "kidding" about putting that 3M tool in a dremel, just the
reference to the rotational mass of the dremel vs that of the drill
with the tool on it, is what makes the huge difference of the
effectiveness of the 3M tool, plus that softish rubber. A real breeze
getting those decals off. IIRC, there was some sort of "prep liquid"
that helped soften the decal first, but I think that's referenced when
you go to the marine/hardware/auto-paint store to purchase it anyway.
