I've eaten up a number of conical mounted stones for cleaning up the insides of
mushroomed chisel sockets, though I have to confess I've usually bought them
new. In my experience, if a power grinder is the same diameter as the curve I am
trying to make, it grabs and tries to throw the tool off somewhere. So far I've
been lucky and it hasn't thrown it at me. So now, I always grind with a tool of
smaller diameter than the surface I am trying to make; with a conical stone,
with a part of the cone that is smaller.
