As the title says. Is it ever NEEDED to be removed? I read somewhere that when sanding or using the flat wire I should remove it, elsewhere I read that wire cup brushes must be used with a guard. Is there any truth to that?
I'm not asking about personal preference, or "better viewing", etc, I asking about a situation where using a guard would be more dangerous or worst than not using it.
After some research on safety and dangers of the angle grinder, I find a aptly quote that sums my thoughts: "If I need to remove the guards of a tool, maybe I'm using the wrong tool for the job".
