I got this one recently: "Can I use a disc grinder as a cut off tool?"
My first thought was - of course it can, but what are you trying to cut and why would you use a disc grinder to cut with?
I wrote back to ask what they were trying to cut, but since I'm not a woodworker or heavy tool user I never know if there's some inside jargon going on in these questions.
Does "cut off tool" mean anything besides, say, a SAW?
Is there enough in this question to answer reasonably?
