I Had a cutting disc explode while putting new floors in my dart. Took part of my thumb off and had a piece of the disc stuck in my chest like a Ninja star. Gave me a new respect on safety issues. I was wearing a full face mask that day or I probably would be blind now. Take it from Me, NEVER EVER remove that small guard thats on an Angle Grinder for any purpose, its on there for a reason.
