Alpha Porcellana Wet Diamond Blade

Had purchased several blades (all supposedly the top of the line per manufacturer) at local stores and was not happy with the chipping I was getting during cuts. I contacted contractors direct and asked if they could recommend a good blade. they responded "Our best diamond blade available is the Alpha Porcellana. Some other well reviewed blades are Pearl DTL10HPXL and Terminator." So I decided to try the Alpha Porcellana. This is by far the best blade I have ever used. Fast cutting, almost no chipping and difficult to tell which side is the cut side. I definitely recommend this blade and thank contractorsdirect for their recommendation.

Purchased this specifically for a home project that involved cutting 18x18 tiles (diagonally) - the advertisement "best blade to cut porcelain" was the main driver for this purchase. The blade did not disappoint - clean cuts with no noticeable chipping. In hindsight, I should have purchased the smaller 7" blade (or even 5") instead of the 10" - might have drifted a bit less than the larger blade when making small adjustment cuts.

Overall this is a fantastic blade, much better than the original blade that came with my wet saw. After reading all of the reviews, I expected a blade that didn't chip the tile at all. Granted I was a little disappointed when small chips appeared, but they are dramatically smaller than the original blade. When making small adjustment cuts, it has a tendency to drift, but again much less than the original blade. Let's just say that I would buy one again.

First of all, this 4-3/8" blade make fantastic glass smooth cuts with no chipping. The bad, the description say it required no dressing, but that does not seems to be in my case. I used it for cutting 18 x 36 porcelain tiles with the Alpha AWS-110 wet saw and rail guide system. The first time, I was impressed how fast it cut the tile, leaving smooth cut. The next few cuts, I had to put more force on the saw to cut into the tile to the point where I fear the tile will crack. The cuts were no no longer straight as the blade had wandered off the mark. I dressed the blade on a concrete paver following the website instructions making a dozen cuts into it. After that, it just barely cut the next tile without too much force. Finally, I reversed the blade, and now it cut much better. Not sure if that is a good thing.

I am using this blade to make 3 1/2 x 3 1/2 tiles from 20 x 20 tiles we had left over from a floor job. The smaller tiles will be used for a back splash and edges will be very visible. We needed clean (not ragged) cuts and are getting this with this blade. I still have more to go, but this blade has out shown any other porcelain blade I have owned.

I read all the reviews of this blade and thought I had found what I was looking for. This blade does not even come close to the raves about. It dulled after the 3rd cut. Maybe my saw needs to be adjusted, I don't know, but I am not happy with this purchase.
