Grinders are scary tools. At least the pneumatic are controllable. Electrics not so much. Wonder why adjustable electrics are rare?
I better put the guard on mine!
Glad you're ok.
I was cutting a bolt with a 3" wheel on a die grinder. It grabbed once and I said to myself WTF am I doing? grabbed the 4.5" grinder with the guard and zipped the bolt off.
Adjusting an electric A/C is harder than a rheostat on a D/C. A/C needs to be duty cycled or frequency modulated. Expensive on a 15-$35 device, although buffers have them. Maybe its the amperage they draw.
