ZORUNNA 5 Pack Glass Cutting Disc for Angle Grinder, 4" X 7/8" Tile Cutter Blade, Ultra-Thin Glass Cutters Tools for Grinding Ceramic, Crystal, Tile, Jade, Wine Bottle.

Works great at a fair price. I actually purchased it to cut one piece of tile. Overall very satisfied with the product and the price point is reasonable for the quality.

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’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.

Love these for tile work, I would definitely buy again

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

These disc are amazing gives an extremely clean cut

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.

Funciona bien pero un tanto grueso

Bought these blades for cutting large format porcelain tile with a glass glazed surface. I used it on my 18 volt grinder with speed control. Discs made cutting easy. Scored the surface of the tile first and then went back for the plunge cut. Noted that I used a spray bottle with water and sprayed the disc blade as I cut. This reduced the chipping and provided a more clean cut of the tile. I also cut the tiles dry and there was a lot of dust produced. But this also feels like the blade wore down quicker and was not cutting clean. I replaced the disc with a new one again and applied water to prevent disc wear. You know the disc blade has worn down when the cut is no longer smooth and its takes more time to cut the tile. I also used these blades for glass style back splash mosaic tiles. Cuts were clean and made the work easy.

EDIT: My original post below was a bit premature. I changed the setup and used the grinder freehand cutting mosaic tile (glass and aluminum strips) in sheets. I taped the cut line with Frog Tape at least an inch each side . The difference was remarkable. No chipping of the glass strips and the blade cut through like butter. The frog tape is definitely a game changer. Used this blade on an angle grinder mounted on a stand to cut mosaic glass tile. It failed every attempt to cut the tile without chipping. Went back to a $2.50 30 year old glass cutter to get the job done. Works on aluminum.

These blades cut very nice. I only wish they would last a bit longer when cutting hard floor tiles.
