Review on DEWALT Diamond Cup Grinding Wheel, 4-Inch (DW4772T): Ultimate Precision and Long-Lasting Performance by Fred Meeks

Excellent grinding disc for leveling cement. Don't use it on a weak angle grinder. I burned out the motor of a cheap grinder in about ten minutes while leveling the cement ramp leading to the garden shed. I put it on a "fine grinder" and easily finished the job in minutes. Wear proper protection as the wheel ejects a lot of dust. Don't stop spinning the wheel as you will most likely crush the indentation. I leveled the pads on the forty-year-old concrete to secure the posts for the platform deck. This kid made it, although it took some work. In short, this is a very aggressive grinding wheel that works great when used properly with the right equipment. I did wear out the wheel badly on the old hard concrete, but that made the hard work a breeze.
