5 Inch Diamond Drill Bits Glass Hole Saw Drill Bit Set for Glass Ceramics Porcelain Ceramic Tile Marble

Worked as expected. Cut a very pretty, clean, circular hole in the shower tile and cement board when installing a new shower faucet. I highly recommend using the "cut a hole in scrap plywood and use that as your cutting guide for the tile" approach rather than the "start at an angle on the tile, then rotate to the circular cut" method. I cut my circular hole in the plywood then taped it to the wall where I wanted the hole. I paused every 10 seconds or so to dip it in water and clear debris from the cutting surface.

Was skeptical because it took so very long to drill through the tile with a diamond tip bit. Had to make a pilot hole because of a specific need for an exact location in a closet. Read all reviews and followed instructions using water and drilling slowly. Was amazed how easily it cut through the tile. Clean cut! Thanks to Amazon for sending me this suggested tool. So much less cost than buying Bosch, adapter etc. Only needed to drill one hole. Couldn’t see spending about $100 for another name brand.

Works great

Best hole for a toilet.

Cheap and it worked but without a pilot drill it wandered too much and the hole in the tile is not perfect.

It did the job in drilling thru stone but not easy, did not like the shaft it is way too shorter than others and being round. Why round and not hex?

My wife uses these to cut holes in bottles and these are the best she has had, they are the sharpest and the fastest cutting diamond hole saws that she has had.
