Made a plywood jig to make these drill bits work with precision since they don’t have a center drill and I couldn’t find any diamond hole saws in this size that did. Made a 4.5″ hole with a 4.5″ wood hole saw for my temp valve and a 2.5″ hole with a 2.5″ wood hole saw for my transfer value (both measured and aligned, of course). The piece of ply wood was routered out to be the same size as the tile exactly. Placed plywood perfectly on top of the tile, filled the two holes with water for cooling, and started drilling with my Makita cordless on the fast setting. I had my two perfect holes in probably just over a minute’s time and I didn’t have to hope and pray like I would have to using an angle grinder. The tile looks like it came from the factory with these holes, they are very precisely cut. None of that ugly, jagged (even though you don’t see it) crap you often see. The smaller and more precise the hole, the less likely water will find its way to wherever it wants to go.

Bottom line hit cut a hole that was 2 5/8 inches.
So here’s the review I cut three holes and my glass. The glass is a half inch thick. I didn’t have any problems with the drill bit drilling those three holes other than the holes turned out 2/8 of an inch bigger than they were supposed to. The best advice I found online for drilling glass was 1. Set your cordless drill to stall at the very easiest setting which is the number one position so you can stop the bit from turning even at full speed with just your hand 2. Drill a hole through wood with a wood hole saw to use as a guide to get the grinding started. 3. Use the least amount of pressure possible as the bit breaks through the back side of the glass.
This was the first time I’ve ever drilled glass. I would not buy this drill bit again just because the bit drill the hole that was bigger than it said it would drill. Again it did not drill a 2 1/2 inch hole it drilled a 2 5/8ths hole

Among other minor tile cuts I used this primarily to cut two overlapping holes for electrical switches & outlets (followed by only minor work with the tile nippers to remove the remaining little points between the holes). Only trick is to begin cut by holding saw at an angle to the surface and of course never run without water. After 25 or more holes cut in porcelain it was still cutting as good as new.
