4 3/4 inch Diamond Hole Saw for Cutting Porcelain, Ceramic, Glass, Tile, and Granite Perfect Circle Tile Cutter Diamond Coated Porcelain Ceramic Tile Hole Saw

Worked okay, but the 4 3/4" hole saw is definitely squirrely when you load it into a power drill. Placement is also difficult since the drill doesn't spin as fast as a grinder, so it takes a second longer to bite into the material and it wants to skate away across the tile. Overall, it's hard to control, but cuts a decent hole. I used a constant stream of water to keep it cool, and placed a scrap tile underneath to prevent blowout.I cut one porcelain tile, and I'd expect to get "maybe" one or two more holes out of this tool before it goes dull. For the price though, it's hard to beat.

Worked like a charm. We needed this to put hardware in our remodeled shower. Worked great. We were told by a professional to spray water on hole saw while using to extend life so we did. Only downside is the is no pilot drill

I was skeptical at first because of the lower than expected price but was absolutely amazed at the quick and precise cuts I made with this. As a tile-r for over 40 years your end product depends on quality tools. This is definitely a quality tool.

As long as you keep the tile wet as you’re drilling the hole, it works pretty good. Good value for the money in my opinion.

Fast cutting and long lasting as long as you use water as you cut.

About the only way to get a clean hole in porcelain or stone tile

I sent it back

Have cut three perfect holes so far with little visible wear. I recommend water to keep everything cool and something to back up and support where the hole is being cut will help.
