Why cannot it be used as a cut-off tool (as per manufacturer's manual)?? Very disappointing, since cutting-off is the main use for cordless tools.
Asked by: Neil
It's mainly because of the guard, however you can buy and put the Ryobi guard on the Ridgid grinder to have the correct guard for a cutoff wheel. The Ryobi cut off guard covers the back side of the wheel.

Does This Tool have a paddle on-off switch

Does This Tool have a paddle on-off switch
Asked by: Terry
No, it has a thumb operated switch on top that when pushed down and forward locks in place. A touch on the rear of the switch then disengages it which turns the machine off. I struck mine on it's side with my gloved fist while it was running and it turned off so if it were dropped while operating I believe it would stop.
