Review on 💎 High-Quality 6" 150mm Grit 320 Diamond Grinding Disc for Jewelry Tools and Gemstone Glass Ceramics by Robert Hayes

These diamond blades offer excellent value for money. I have a GRS Power Hone and at $100 per drive it's very expensive. I really had to put a main circle or backer behind the discs or even double them to get rid of any wobble. All in all these are great wheels, I've ground many engravers and the wheels are still in great shape. I carefully sharpen carbide tools and some HSS to give you an idea of what I do with discs. I think I can sharpen more engravers with $10 for a x10 disc than with 1 disc at 100. I will buy them again if needed. And would recommend it.
