Review on 🛠️ Efficient Grinding Wheel: POWERTEC 15508 6" x 3/4" with 1/2" Arbor and 150-Grit Silicon Carbide by Bishnu Bush

As far as I can tell, this is not a silicon carbide wheel. I had not finished sharpening a dull carbide blade and was covered in dust with a huge groove on the wheel that was almost 1/2 inch deep. If you look at the carbide on the tool, it wasn't even scratched. on my hand grinder did all 32 cutting blades on my machine and showed almost no wear. If you need to sharpen carbide tools, check out other silicon carbide discs. Update: I got a real Green Wheel silicon carbide and took a picture with it and it is left of Powertec and the normal whetstone. You can clearly see that the POWERTEC stone is closer to the normal whetstone. DO NOT BUY, even as a normal stone, because they claim that it contains silicon carbide, you would be stupid, this without using a respirator, and it works no better than an ordinary stone wheel.
