- Delta Diamond Piranha Premium 10 Inch Tile Saw Diamond Blade, 5/8" Arbor, Continuous Rim, Wet Cutting Porcelain Tile, Ceramic Tile, Stone (10")

bought this for cutting hard agate and petrified wood. Cuts very well, much faster than other blades I've tried. I noticed in some of the other reviews that folks complained about the blade getting dull. The cutting does slow down after cutting a dozen or so hard stones, but sintered blades need to be peened to remove the glaze that covers the diamond. Once peened, new diamond is exposed and the blades cut like a champ again. Apparently, some folks do not know this and it extends blade life a lot.. Overall I'd rate this as a very good blade.

Worked great on porcelain tile. Very limited chipping and usually was because I needed to do a pass on a dressing stone. After sharpening it cut like butter again. The only thing I didn't like was how fragile the middle insert was. I bumped it on my first blade, it fell out, and I could never get it back into the middle. Ended up having to get a second one. I treated the second one more gently and it worked great.

Rock hound here, this thing cuts rocks faster and better than a slab saw...on a trim saw. It would cut through anybody else's saw. I cut several Brazilian agates in about 2-3 minutes each, it went Beast-Mode on them. Only caution I wouldn't use it on the small agates.

These worked pretty well cutting rocks but the quality isn't that good and they dulled rather quickly. won't purchase again.

I used the blade to cut 1" × 2" stone on a mesh 12x12. Needed to cut slowly or stone would chip toward the end of each piece. The center of the blade had a round insert instead of a diamond shape to fill the void. When I removed the blade to clean the wet saw the center fell out and I had to replace with a insert from an older blade . Having a better center would make the blade a much better product. Cut well and did the job

I made several dry cuts to a marble countertop with my old grinder. The Grinder got very hot and I was afraid that the grinder would not withstand the harsh treatment that I was subjecting it to, or that the disc would melt due to the friction caused by cutting the marble stone dry. But I managed to finish everything without a hitch. The cuts came out perfectly aligned and without splinters. And the disc was left as if it had not been used. Ready for another project

Nice! I had to cut through about 48” total of 5/8” marble countertop for a kitchen remodel. This worked well. Put it on a Dewalt circular saw, had the area enclosed with taped-up plastic, and a shop vac running the whole time. Cut well and dust was minimal. Beat the $800 local shops were quoting, and it is done where as they were to 8 weeks out. January 2021 - cut about 8 lineal feet of (soft) slate and then another 4 feet of granite with the original blade. That pretty much used up its life. Not bad for the price. By this time I had upgraded to a Skil saw with a wet cutting attachment (outside of course for these wet jobs). I ordered another one and got through the last of my granite job.

After about 30 cuts the bushing for the blade mount came loose. Once the bushing came loose, the blade would vibrate during a cut and began chipping tiles. I bought this blade to cut ceramic floor tiles. It worked good for a while, then it began destroying tiles. The bushing was not part of the blade and was staked to hold it in place. I purchased a different blade to finish the project.
