Review on 🪓 GRAFF BLACK 4 1/2 Metal Cutting Diamond Cut Off Wheel - Angle Grinder Cutting Wheel - 60x Longer Life - 115 mm by Tom Tucker

Yes, the title is spelled correctly. Advantages: The diameter does not shrink as with conventional grinding wheels. Cons: Doesn't cut. Given the cutting speed of this wheel, the "3,000+ cuts" of 12mm rebar claimed in the ad probably took 3,000 hours. The ad said they used 12mm (1/2 inch) rebar for the 3000 cut test, and later the ad said 【Hacksaw blade is not suitable for cutting thick metal】. I don't know how they define "thick", but it's useless for .187" mild steel and not much better for .062" (1/16") thick. not a complete loss.
