.. Grinding carbide is
also fairly dangerous to your health. As I've gotten older Carbide dust
will make my heart pound. Probably the Cobalt. The dust from carbide
grinding is carcinogenic as well.

I've always been quite sensitive to the dust from ductile or cast iron.
Luckily, very few of the jobs I ever held machined very much of either one.
When I had to do it in my own shop, I used a vacuum cleaner that discharged
outside, so the dust wasn't much of a problem. It's not a bad idea to
avoid breathing these things, given a choice.
