ROCKPORT Turbo 4 1/2 Diamond Blade for Angle Grinder Set - (3 Pack) Diamond Saw Blade & Grinder Blade for Dry/Wet Tile, Diamond Cutting Wheel for Stone, Granite, Concrete, 5/8" - 7/8" Arbor Tile Blade

Product arrived quickly and worked well for me. Cut some granite.

Exactly what I needed to turn a 24" square concrete paver into a 24" hexagon. Easily scored and cut through this with multiple passes for minimal effort. Easy to control it's aggressiveness. Every bit as good as higher priced diamond grit blades.

I wanted to improve the look of my cinder block chimney by facing it with some brick veneer. I used a couple of these blades to cut the brick (which was about an inch thick). They worked effortlessly and I'm certain if I had full brick would have been just as good. I'll be doing some tiling shortly, so I'll have a chance to use the tile blade on my grinder but if it works as well as the others, I'm not expecting any surprises. Overall, very pleased with these

I'm not cutting concrete, but I do cut a lot of tile. These do the job just fine but quality wise I am not sure how long they will last.

The media could not be loaded.  These Rockport diamond blades fit perfectly on my angle grinder. Used the segmented diamond blade to refurbish an old concrete window sill. Scored both sides of the piece I wanted to cut off and chipped off the rest. Gave an easy and consistent cut. Also tried out the turbo blade on a hollow brick wall and cut with ease. I have yet to try the tile blade. For the price point these blades are worth the buy.

Three diamond blades that feel and look like quality built blades. high concentrate of diamonds grit on the blades. Says on each blade what they are best for, and Fit grinder perfectly. Nice buy for the price.

I ordered this set of blades (along with some others) for some tile cutting. The blades are 4.5" in diameter and have a 7/8" arbor. These blades have a relatively thick cutting edge that is flat and blunt.I tested these blades by dry-cutting some limestone tile and concrete brick.I used the tile blade and the turbo blade to cut the limestone. Both blades chattered terribly while cutting and left hugely gouged and chipped canyons in the tile.I tried both the turbo blade and the segmented blade to cut the brick, and while they did cut the brick the cuts were sloppy compared to others.These blades are the worst performers of any I've tried. They're sold as diamond blades but I don't see a lot of diamond on either the cutting edge or the sides and their performance bears that out. I'm not inclined to try them again and can't recommend them at all.
