I used the Grinder with a Masonry wheel to repoint my brick steps. It did an excellent job.
Purchased to replace a Craftsman grinder that was over 25 years that finally gave up due to a broken switch. Old grinder was an excellent product; new grinder seems much less so. Quite a bit of gear noise and the power switch appears to be substandard. Plus, new grinder shipped without the spanner wrench to remove the grinding wheel. Luckily, I had an old spanner wrench that would work. Not satisfied at all. Cheap Chinese but you get what you pay for.
