Works great!
Used this to drill a hole for a filtered water system in my porcelain/cast iron farm sink. Did great, no chipping or breaking on the sink. Perfect hole!

Excellent diamond bit for
This bit works very well for shower tile. The center bit helps to start the hole precisely, without any traveling. Once I’m about halfway into the tile, I switch to a different 1 1/4” diamond bit (without a center bit). You can also just remove the center bit with an allen key.

Worked as hoped for imported tool
Needed to drill a hole in brick front of house for irrigation plumbing. I used a 1/4" cement bit I had already to drill a pilot hole. Start slowly and while rotating the hole saw as your helper constantly sprays water on bit and in hole. I used an empty windex bottle and put water in for spraying. The brick was harder than I anticipated. I left the attached pilot bit in for my security. The stone was a little deeper than the hole saw, so I simply broke the stone plug off and finished cutting. Took about 10 minutes start to clean up. Wish the hole saw was a little deeper than about 1-1/4" but oh well. The pilot bit that came with fell out literally as we finished, but never checked how secure it was from the start or anything... Came complete with 2 hole saws inside of a nice plastic holder with allen wrench for pilot bit removal. I had my doubts but worked and the diamond grit was still intact on hole saw and will be able to use again + extra incase... My suggestion is to use a pilot bit if possible, and spray water non stop!

Cuts porcelain tile like butter.
Cuts much much faster and clearer than my cheap harbor freight bits very effective.Plenty of the diamond abrasive and it has a nice sharp pilot bit. Easy to use. Just put the bit in your drill, turn on the water and start cutting. It seems solidly made and the price wasn’t terrible considering you get two bits with the pilots included.

Easier than we thought to drill though granite
Works great on granite. A little time consuming because it takes a while to drill through.

WOW ! Drilling concrete paver
I can not believe how well this worked. I used the lowest speed possible on my cordless drill. Once hole was about 1/8" deep, I removed the pilot bit and continued. Gently rocking really works. Stopped every 1/2" of penetration and broke out the "plug". Note : breaking out the plug should only be done in concrete. Before breaking through, I used a pilot bit without hole saw to break through, then repeated procedure to drill from back to prevent spalling.
