Query: This blade is the best I've seen in a long time!

I am a tile installer with about 30 years experience. I am using this blade in a chicago brand 4 1/2" grinder from Harbor Freight and it works great right out of the package. Usually I have to 'break in' blades like this. Especially if they are meant for using as a 'wet' blade. I am using it dry to cut tile. It cuts flawlessly on the tile I was setting this week. I was pleasantly surprised that it cuts so well in the dry mode with the grinder like that. If you are looking for a blade to cut tile without chipping this is the one. You will need a 4 1/2" grinder because this won't fit in a 4" one. Barely fits the 4 1/2".
