If you are renting a commercial grinder from an industrial tool rental place get the largest grinder you can use. Insist on new bits of at least 20 grit or so. Otherwise you will be there for a long time grinding with worn out bits or a small dinky machine. If a Vac accessory is available for the machine, get it. There will be a lot of dust when you grind and Shop Vacs will not work, they will clog up in two minutes. Even with a good Vac system you most likely will still have to wash the floor to get rid of all the dust. Apply some duct tape to the floor and see if any concrete dust is stuck to the bottom of it when you pull it up. Dust on the tape is not clean enough, no dust or a miniscule amount means you're good to go.
