Use the 9 inch angle grinder. They are not heavy at all. I have a 9 inch Makita a Bosch & a Hitachi one. P..cing around with a toy is for girls. Get hold of the thing & use it. You will be through the steel before you know it. By the time you have changed blades loads of times on a 4.5 inch grinder the job will be done. Do not bother with diamond blades. Adjust the guard so you get a comfortable position.
DO NOT FORGET THE GOGGLES for eye protection. Stand to one side so the sparks do not burn the embarrassing bit out of your trousers,Do not do it next to the wife's car & do not drop it on your foot with the blade running
Place the steel so the cut opens up, not closes so it jams the blade.
"do not drop it on your foot with the blade running" I've done that and I was only wearing
I managed to get to the house, couldn't find appropriate bandages immediately, the kitchen floor was awash with blood. But eventually I found an elastic tubular type bandage and used that as a sort of tourniquet. Then slipped a couple of tight sox on my foot. I then drove down to the Medical Center where they stitched me up.
As Daydream Believer says don't forget your goggles.
But I will add the need to wear full length trousers, wear proper shoes/boots and know where your emergency first aid kit is.
