EZARC 4-1/2 inch Super Thin Diamond Blade, Diamond Saw Blades for Angle Grinder, 4.5" Tile Blade for Smooth Cutting Porcelain Ceramic Granite Marble Tile, 7/8"-20mm-5/8 Arbor (2-Pack)

My trial cuts on 1" porcelain went very well. See below. I'm very happy with this wheel. My DeWalt DCS690 normally uses a 9" wheel. It has a 7/8" arbor. A 9" wheel is good for cutting bricks. Cutting 1" thick porcelain tiles is better done with a smaller diameter wheel - this 7" wheel seems to be ideal. See below. Watch out: there was no sign of the advertized 7/8" and 5/8" arbor reducers UNTIL I opened up the package. Printing on the packaging only mentions the 1" arbor. Nothing about the promised adapters. I almost sent it back, but opened it anyway, and found the needed adapter was hidden inside. The packaging needs to be updated or there will be a lot of needless returns.

Great grinder wheels, cut were clean and smooth. Highly recommend

Made cutting tiles a breeze. Used these over a conventional tile saw to try and reduce edge chipping on large format tiles and worked well. Steady hand and nice and slow to get the initial couple of passes and after you get the hang of it you will find it easier than the table saw.

Did a great job cutting porcelain tiles. Did one shower and the blade still seems brand new. I also really appreciated the thin kerf.

This blade cuts very well and was easy to install. I was able to complete my entire project using just one blade, which was impressive, and now I have a backup ready for the next job. Great value if you’re working with tile or similar materials.
