GoYonder 4 Inch Super Thin Diamond Saw Blade for Cutting Porcelain Tiles,Granite Marble Ceramics (4"-Blue 2PCS)

I used the blade to cut ruby. It is a bit wide and wastes material but cuts easily, stays sharp. The center hole is a one inch diameter, not the smaller size quoted! Over all, the blade is well made with diamonds well mounted and showed no wear after 10 cuts and inch deep. After mounting in the saw, the blade ran true. I use water as a cutting coolant. It works better if you can feed really hard material slowly and evenly, with the material ether clamped or glued down to avoid breaking the last little bit, sort of a sled with a screw feed.

Very nice blades, nice and thin and hardly any chipping will definitely buy again

We bought this to make a small 1/4" cut along a granite countertop to put in a stove. It worked perfectly and cut the granite nicely and quickly.

I didn't know what to expect but was very pleasantly surprised. I used a 4.5" angle grinder to cut 2" deep grove into concrete that had embedded pea gravel throughout. It went very well; took 45 min and the blade is worn, 30%+ left (80+ of diameter left) but I literally cut 20+ linear feet through concrete with stone in it and no water cooling. yes I tool very short 10-30 second brakes to cool blade but it went very well. I am using a cheap harbor freight saw/grinder.

Great blade that cuts like butter

excelente producto

Disco de muy buen corte, muy fino

I bought this blade to cut rocks on a wet tile saw and of all my previous blades, this one is quick! It's also pretty aggressive while cutting, leaving no room for error if you have to turn the rock. When installing, I realized the radial center of the blade was thicker than other blades, and made it nearly incompatible with my saw. It's blue paint wore away quickly on the rock as I was cutting, but otherwise the blade is fine. It does as described but doesn't leave the cleanest surface. Overall, if you are trying to get through a rock with little regard for a clean cut, this one's for you!

Super produit je recommande fortement découpe Propre

Coupe super bien

I only had to make a few cuts in porcelain, but the cuts were perfect!

全然切れん

I have taken my time, since i received the product, to test it extensively. So far i have cut through ceramic, porcelain, sinks, toilet units, you name it. I absolutely love this product and will order more in the future. The disc, as stated in the description, is very thin, which allows for precise cuts. It is not aggressive, compared to the standard diamond/ruby-coated ones. The cuts are clean, depending on the material of course. I find that ceramic, when cut with this disc, tends to chip a bit on the edges, but i expected it to be honest. The durability of the product is immense. I have cut through countless pieces and it still is pristine. When cutting, there is less attrition/friction with the material so u find that i am using less force compared to other discs. Now, please bear in mind that you should take all the precautions possible when using this product. It produces noticeably thicker dust than your standard coated disc. This dust gets shot at high speed, so use a shield on your power tool. Also wear glasses and a dust mask, mandatory. Being the disc thin, you need to have a very steady hand when operating it or risk snapping the disc and causing some damage. Always use two hands, don't do any cowboy show. Ultimately, the big question: water, yes or no? Normally i would always recommend plenty of water with these kind of cuts. Why? Cools the blades, preventing expansions (and then cracking), greatly reduces airborne dust Hope this
