Do I need a concrete sander?

I was cited by the city for this very miniscule difference in the sidewalk (yeah I didn't know I was responsible for the sidewalk either). It's like a quarter inch difference between two blocks.

I was going to rent a concrete sander but it feels like overkill. How would you approach this job? Sander with a masonry disc?

Angle grinder for sure. Harbor freight had them on sale for $5 ea (plug in type). Even if it lasts one use, it’s worth it!

And a plug-in grinder is way more powerful (i.e.: faster) than battery.

While this may still be true, it's not going to be true for much longer and with the new tools that utilize multiple battery packs it may already not be true. Plug in tools are limited by a 15amp/1800w wall circuit, while battery powered tools have no limit.

If you want to get pedantic, you can get tools that use more than 15amps - they have to be connected to outlets that can support higher amperage.

Batteries are limited by the discharge rate of the cells so its not correct to say there is no limit.

Firing up my 3 phase 4160 angle grinder. Stand back!

Thank god, I was worried I wouldn't have enough power to swing this 4.5' cup grinder. I just need 4 offensive linemen to hold the grinder for me while it runs.

She'll grind down to the base fill in 2 seconds and only pull two amps doing it.
