Drilled 3 holes in ceramic tile in less than 5 minutes. Cut through it like butter. Used less than 1 bar on my Milwaukee 5AH battery. Was prepared to use water, but it cut through so fast and never got hot, just slightly warm. So water was not needed. Bit still looks new except for the black paint rubbed off from wobbling it around into the sides of the hole. These will now go onto my shelf and possibly never be needed again. But if I do ever need them again, I will be happy I have them.

These were great and did the job perfectly! I just went slow, added water, and they cut through 1.5in granite easily. I bought these because of pilot bit in center, which helped ensure it wouldn't skip out of hole and scratch counter. You don't need to spend a lot on fancy brand names for this tool. I would definitely recommend.

I used this to mount an in wall bracket for moen shower hand rail. They’re used when the studs don’t line up. Cut right into tile. Not sure how long it would last but cheap and done worked for me. Might spend more if daily use was needed.

When using drill small pilot hole using a smaller carbide tile bit. The bit it provides does not go through ceramic very well. Once using the main bid and into material aways you can remove the center bit. The main hole saw at low RPM works great dry. Tried water with it and it stop cutting. Dried water and continued through tile without any issues. Nice clean hole. The side diamonds great for enlarging hole as well.

Works well. Used it to cut a hole into an 1850s antique bowl to use for a vanity sink--delicate job! Mission accomplished, with no chipping or breaking.

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.
