Shit dude.. you most likley walked away lucky on that one.. I think we've all had a few close calls with this type of thing.. When i first got started in this trade, i had to go in a few times for wood chips i couldn't get out. Knock on wood, i now have a half decent technique i use directly on site to get stuff out. (Just a truck mirror & makeup/mascara pointed q-tips to dig debris out. I'd have to believe flying metal would be allot harder to find or remove though.
I will say this.. noticed the cheaper harbor freight wheels/disks/wire wheels will throw a ton of debris at me vs higher quality ones. I've also noticed i can't just use any old pair of glasses for protection & be able to relax my eyes while cutting metal or wood as I've had exactly what happened to you, happen to me while wearing glasses. This is because alot of glasses leave a big opening underneath the bottom of the lense. To prevent this, i will test fit the glasses to my face & I'll only buy glasses that will touch the tops of my cheek/cheek bones without haven't to squint very hard. They're even better for me if they touch without doing any squinting. Knock on wood again.. since I've adopted that standard, I've not had anything get past. I know it sounds silly, but try it out.
