Can you grind concrete with an angle grinder?
An angle grinder can be used to level, smooth and polish concrete by grinding it down. They can also be used to remove paint and floor adhesives. To grind concrete with a angle grinder you need a diamond cup wheel, a dust shroud attachment, and a vacuum cleaner.

If your concrete cutting work are really occasional, a manual angle grinder works fine for light-duty cutting work. A concrete saw is essential for heavy duty concrete cutting.
How do you grind high spots on concrete?
For a small job, rent an angle grinder equipped with a diamond grinding wheel ($50 a day or less). It’s the perfect tool for taking down just a few high spots or tough-to-reach areas near walls. Be sure the one you rent comes with a means of attaching a vacuum to suck up the dust.
Why do you grind concrete?

What is the best blade for cutting concrete?
Diamond saw blades are typically the best choice when it comes to making clean, professional cuts in concrete.
Can I cut concrete with a circular saw?
Use a standard circular saw, equipped with a corundum or diamond blade, for small tasks. For slabs, it’s best to cut through the top inch, then use a sledgehammer to break off the rest. The jagged edge left below the cutting line provides a good rough edge for the new concrete to bond to.
How do you sand a concrete floor by hand?
Attach 180-grit sandpaper, which is a fine grit, to a pole sander, hand sander or floor sander. Put on a respirator, and sand the entire surface of the floor lightly. When the sheen is off the surface, scuff sanding is complete.
