Review on 💎 Premium SHDIATOOL 4-1/2 Inch Single Side Coated Diamond Grinding Disc: Ideal for Granite & Marble Cutting - 5/8-Inch-11 Arbor by Marcus Price

Finally a grinding wheel that I can use to sharpen my teeth to grind tungsten carbide stumps. This works well to re-sharpen the teeth that round off on my punch. And it doesn't last a day. Good product! I will order more in the future if they ever wear out. Update 1/3/19: They are still amazing. The photo does not show the diamond coating reduction that I see. They don't seem to wear out and I've sharpened hardened steel chopper blades, cut through 5/8" bolts and various other steel plates, etc. Love the fact that they don't break like commonly used aluminum oxide discs.
