Review on 💎 4" Concrete Grinding Wheel: Heavy Duty Turbo Row Diamond Cup Grinding Disc for Granite, Marble, Masonry & Concrete – SUNJOYCO by Rodney Nelson

It never fails. You ALWAYS get what you pay for in life, but for some reason I still try to go the cheap route sometimes. Well, this cheap "diamond" saw is complete junk. It won't fit in a 5/8 mandrel regardless of whether you use the ridiculously thin washer/sleeve they provide.2. After the jury tried it with my wide variety of tools and jigs, it didn't work well on concrete.3. You know, when something costs 1/3 the cost of port freight, beware the buyer. Finally, HF is not known for quality tools and attachments, but they are too cheap and poorly made for Harbor Freight to sell.4. In my opinion you are wasting your $10 if you try this. If you need this for a project you will be very disappointed.
