The best All Around grinder blade ever made!!!
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!!!

Good disc
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.

Works perfectly
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.

Good blades but they wear out quickly
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.

Son muy buenos para los cortes

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.
