I use a 9 inch angle grinder, the discs are cheaper & when its worn down to 4 1/2 inch dia, you can put it on a smaller grinder. It takes a lot less energy to use & its way quicker, I get about 12-15 compressors to the 9inch disc.
I have used grinders for decades & have never really had a bad incident with them, 'cept a small cut in a left hand knuckle I had to get stitched together with 3 stiches, tiny deal...
HF has this 9 inch grinder 9" Heavy Duty Angle Grinder
Incidently, they guys holding it wrong... Handle should be in the left hand sides position & the grinder should grind in the 2 to 5 o'clock position on the disc, so if it grabs, it pulls the grinder away from you.
Cutting vertically, right hand on the switch grip, left hand - thumb up- on the handle. If it grabs it will pull the grinder up & away from, and to the right of the operator.
ALSO, make sure the bolts holding the angle geardrive together are always tight, if they loosen even the slightest it will wear away the gears teeth real quick & they will strip & the grinders ruined, all in 15 mins.....
