Yes I agree generally with that, but however not in this case as it is a different situation, you are not running a 9" full size disc at 12000rpm, you are now running probably a 4-5" disk at 12000RPM which mine does, so in effect the centrifugal force is no where near what it would take for the disc to fly apart and is probably the same as running the 9" disk at a slower RPM.Please do not do this, 9" discs are only rated for around 6000 rpm, smaller grinders turn at up to 12000 rpm! So you could be running the disc at twice its max rated speed a few inches from your body!
Put it this way - your car engine might red line at 7000 rpm. What do you think would happen if you could rev it to 14000 rpm?
At the end of the day, I have not had one fly apart on me in 45 years but it is up to each of us to decide if you want to do this.
My De Walt 9" has the soft start. Thing is that it also has a 2000watt motor. Wouldn't be without all the grinders in small 4" up to 9".
Then you can add the petrol Partner. or similar Cut Quick. Beauty of that thing for cutting through, is that it has a clutch that will stop drive if you go too deep so not the same kick back, as it just bogs down till you pull the blade out of the metal or stone.

I had to go yesterday and cut a vandalised security lock off a gate. Borrowed a Chicago battery grinder from my sons work. Put one of my discs on, metalynx pro. The two of them made very light work of the lock. I thought the lock would have put up more of a fight.
