          Worked perfectly to cut a drain hole in porcelain tile in my laundry room. I haven't done much tiling and have never tried to cut a hole like this and was a bit apprehensive. I used this in conjunction with the Bosch HDGQA 3/8 in Autostart Carbide Hole Saw Quick Change Mandrel to allow the drill bit to connect to my standard drill and to align the 3 1/4 in saw perfectly on the center of the hole. First I marked the hole and the center. Then I used a small tile bit to make an impression in the center of the hole (to line up the saw later). Per another reviewer's recommendation, I built a dam around the outside of the 3 1/4 in hole with plumbers putty and added ice chips and water to keep the saw cool. Then I lined up the mandrel in the prestarted hole (since it was getting hard to see the lines with the water) and drilled. It was the easiest part of the job.

          We used this hole saw to cut through some ceramic coated metal panels. Worked great.

          Works very good. Use a battery drill as they recommend.
