ZORUNNA Glass Cutting Disc for 4-1/2" Angle Grinder, 5 Pack Glass Ceramic Diamond Cutting Blade Disc 7/8" (Model 115/125) for Grinding Jade, Crystal, Wine Bottles, Tile.

Professional tile contractor... These blades work well and cut glass and porcelain tiles clean, but with caveats. The abrasive sides are more aggressive than the rim, so the blade will tend to wander with even a slight side pressure. Makes cutting straight lines challenging. The diamond bed on the rim is thin and wears out quickly. I only get about 8-10 linear feet of cutting before the blades are done. There's no gradual wearing out. They just stop cutting. Good deal for a DIYer small project. But not for larger professional settings.

Todo muy buena calidad

It did exactly what it was supposed to do. Only wish I had knew this product sooner used it on a angle grinder and felt comfortable after a couple passes.

Will cut specified items and WILL leave some abrassive areas.

These blades are decent for the price, but do not last very long. But if you want a good value product, you’re definitely getting your bank for your buck with these blades for sure.
