lso, is there a chance of the brazed tungsten tooth flying off the cutter
It has happened.
But far more commonly the tooth breaks, so less than a full tip flying at you.
Trusting you at least always wear eye protection for any sort of chip?
And keep important body parts well below the line of radial fire?
A friend once told me that another friend's dad lost an eye to starting up a new carbide tipped saw blade without face protection.
The warning it good enough i never verified it. (Sometimes as a kid you hear things that were not quite how it happened, although the fact of more or less severe eye injury was true)
Safety, including respiratory, is a good practice so you can keep doing all the things you love into a healthy old age.
