Review on Diamond Countertop Porcelain Bathroom Installation Cutting Tools via Hole Saws & Accessories by Brian Samuel

Affordable hole saw that gets the job done. Cuts effortlessly through concrete tiles. The shallow depth of cut worked in my application, but keep in mind that the actual hole cut depth is pretty shallow at about an inch. The diamond edge is also narrow, but that's part of the bit's affordable price. Use water to cool down and slow down the cutting speed to extend the life of your hole saw.
