How do I plane an installed slate countertop? (self.diy)

Simply put, our slate countertops are uneven, creating issues in daily activities. I've considered using an angle grinder with a grinding disc, but I'm hesitant. Seeking advice on practical solutions for making installed slate slabs even.

The slabs in question varies in thickness by at least ±6mm, in some spots the extremes are within 80mm of each other.

A belt sander with a medium grit paper, like 120 or 150 particles/cm2 may be the way forward for evening the slab out and then something really fine to finish it off with manually. I hadn't considered that. I too was worried about the angle grinder approach, it's a tool to be respected.

I hope you can move the work outside because it will create a lot of dust.

I would like to do that. But the slab is installed, and supports half of the kitchen sink. So no dice. I've just got to seal it off and use a vacuum cleaner at the same time.
