I could not find a porcelean wet saw blade at any of the retailers in my area. Have not tried it on softer tile yet. Cut extremely dense porcelean tile like butter. It would take 2-3 minutes to cut one tile. Installing a thick porcelean tile floor.

Does not chip the tile I am cutting. Destroyed a brand new high performance blade after cutting about 20 12 inch tiles. I ordered this blade and had it shipped overnight. Expensive but it will pay for itself in one job by saving time. Had it on the job by 11am the next day.

I ordered this blade and when it arrived the diameter was 7.75" NOT 8". However those considering this item should be aware that it is not the size advertised. Since I needed the extra depth I returned it the next day. So I have no experience on the performance.

Rips 16 inch porcelain tiles like a hot knife in cold butter. The MK-225 is a bit pricey, but well worth the investment. Just take your time and ease up a bit when you approach the end of a cut for virtually no chips or cracking.

Other blades require 1/2 inch cut depth or less to get any speed. The blade is a bit coarse but perfect for my use. I run clean water on the blade at all times while cutting. I don't reuse coolant. I use the MK-225 Hot Dog 8" blade for cutting obsidian, jasper and glass into triangles for knapping arrowheads. With the Hot Dog I wade through 2" thick pieces at the same rate. Chipped edges are easily cleaned up by holding them against the side of the cutting edge of the blade while running. I use the blade on a sliding table tile saw.

While the blade I received was not visibly damaged, it certainly did not cut as expected. This made the blade unusable. The real issue was that at the end of the cut, the blade consistently left an 1/8" little knob of tile on one side. I saw the other reviews and bought this blade to cut travertine tile. The first strange thing I noticed was that the width of the cut was substantially wider than the saw blade which is, I assume, due to the slots cut into the blade. I ended up going to a local tile supply store and found a truly continuous rim blade and replaced this blade with it. The width of the cut, while disappointing, was not a major issue however.
