I know that the sanding pad of a grinder can clog up!! It just melts some
stuff because of the speed and heat. Just ask me when I tried to remove
paint from metal and wood. I have been looking for an open pad that can
remove the paint but the heat generated is bad for melting.

I donot know about this. I have seen regular grinding wheels just choked
with soft metal, but the pads on an angle grinder ?? I would not do it
because it ruins the pad anyway.

There are large mitre saws that move about two inchesm similar to the
radial arms saw movement. But is called a mitre saw. Some might call them
chop saws. The miter saw that I have allows for clamping the stock then
angling the saw and angling the blade for a compound cut. This might be
great for metal stock if the correct blade is used.
