When cutting Porcelain tile or the tile most commonly used in quality residential construction this blade is just average. Now in the $60 range I have had much better results with a M&K "Hot Dog" porcelain blade and my favorite is a Pearl DTL HPXL porcelain blade. I have been cutting this hard tile quite often in the past 10 years and can say this Dewalt blade is just average. I had my doubts and had picked it up locally to complete a job when my blade was failing. The Pearl seriously lasted through 15 or more jobs and thousands of cuts where I paid even less at about $55. In summary I would not buy this again unless I'm stuck and don't have time to place an order for a different blade.
I have a 'cheap' (off-name) but powerful wet saw. I've cut 12x12 3/8" granite tile in diagonals and 6x6 1/4" tiles with ease. The blade it came with was ok, but left some chipping. The new Dewalt blade has helped immensely. There is still a small bit of chipping, but much less and less frequently; nothing that is unusable. Overall, I'm really pleased with the blade.
This blade had cut about 400 inches (20 tiles) of porcelain before wearing out. I purchased this blade for cutting 20" x 20" porcelain floor tiles. This is a decent blade for the money. It cuts great with little chip out when new. Chip out became a problem after about 200 linear inches of use. Overall this is a great blade. If your cutting anything other than porcelain I expect this blade would be all you need for a while.
Great blade, I cut over 100 - 3 1/2" thick bricks with it. And it is ready for more.
In fact, unless inspected closely, it would be hard to tell which edges are original and which are cut edges. However, once I adjusted the saw to cut straight and the trailing saw edge did not rub either side of the kerf, the blade made very clean cuts.
I wanted clean cuts, with no chipping, so I could use as much of each tile as possible. I have an inexpensive Wet Saw which I am using for cutting 20x20 Porcelain tiles with square edges, that is, no bevel.
This caused massive chipping on the tile surface. According to Dewalt, the DW4762 blade is designed specifically for porcelain so I decided to try it to get the clean cuts that I needed.
At first, the saw was not adjusted properly, and the trailing side of the blade was rubbing on one side of the kerf. Both sides of the kerf are very straight with no chipping on the edges.
I don't know how other blades would compare, if they would do the same quality job, but for what I needed, this worked very well.
