Toxicity of grinding (steel, carbide, etc)?

10/8/2009· Carbide on the other hand is very toxic to grind, well not the carbide itself but cobalt that is used to bind it together. Cobalt is not something you want inside of you. There doesn''t seem anyway to tell at what exposure levels its silly to worry about it or when you really should be so i err on the side of caution and wear a respirator when grinding carbide
