Review on ⚙️ Gunpla 4-1/2-Inch Diamond-Cup Grinding Wheel: High-Performance Tool for Concrete, Granite, Stone, Marble by Ronald Lunn

I usually tend to leave negative reviews or don't care. However, this wheel is unusual. I tried others and then I saw this. I had a large balcony with a cement floor that needed to be raised to replace the dry, rotting subfloor and create a slope for proper drainage. A lot of work. This thing ripped up concrete as fast as a wheel could turn. If I just wanted to remove the deck sealer I would grease the wheel and it would only remove the tip. I bought two but this bike looks like it will last forever after all the work. Make sure you have the proper protective gear (breathing mask, eye and hearing protection) as this wheel will cause a storm. You can't go wrong with this wheel.
