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.

Worked great, put on my angle grinder, it cut thru glass like butter. Worth every penny if like doing projects.

In 25 years of custom remodeling, my grinder is perhaps the most important tool in my huge tool arsenal. I've used practically every blade on the market, from masonry to glass, metal cutting, and tile, as different blades are needed for various functions. THIS BLADE DOES IT ALL!!!!! I've used them a time or two for glass, and for that purpose, they're great, but they can do so much more. For example, I recently had a ton of 2" pavers I had to cut. I was struggling with my $45 Dewalt double rimmed cut-off wheel, and my Spyder diamond segmented blade wasn't cutting the paver well either. Knowing this was my favorite blade for porcelain tile, I decided to try it on masonry. Let me tell you, these babies (3 blades) cut through over 60 pavers like butter. They are honestly the strongest and most versatile grinder blades I've ever used, and I highly recommend them for use in every construction project conceivable!!!

The price was good and it did a work, but id doesn't last long.

I have used these on a few jobs and they worked well.

I’m a contractor and use these discs for cutting porcelain and ceramic tiles. They deliver clean, precise cuts with minimal dust. Excellent quality and durability for the price. Definitely recommend for any tile installer.

great for cut

From what other reviews have said, I'm sure it works on most glass, but it didn't on safety glass. I has water running over it, and even so it literally took one second before the entire piece shattered. I got maybe 1/8" inch before it all blew. The blade is in good condition still, and they're packaged pretty cleanly. They look and feel good, but I can't do more because the only reason I got it, turns out it couldn't quite cut that type of glass.

Great product. I was able to cute porcelain tile and take a couple inches off of a large granite countertop
