Grinders are very unforgiving if you are careless. I was using a flapper disc briefly, did not worry about eye protection a mistake; caught a little piece in the eye blurry vision for 4 days and the light transistion when going outside caused instant headaches, I wont touch a grinder without a full face shield and thick gloves now!

Eyesight is precious!
