One review said these work well with a hammer drill, and I suggest using one for sure if you are working with tile.
I gave this 3 stars because the description said I could use a power drill and these did not work on tile with a power drill. I'm sure a hammer drill would work, but they should have NOT stated a normal power drill would work.
I use the larger hole drill bits coated in diamonds all the time to drill larger holes in tile. Those work great with my power drill and I thought it would be nice to make smaller holes too. So I ordered these bits (they were shipped fast, packed well), and I tried to make a hole in a tile... didn't do anything... so I pushed a little harder... and snapped the bit in half. I tried using water on the surface with the next bit I tried... and nothing.
So if you are buying these for TILE and you only have a normal power drill - DO NOT BUY. If you have a hammer drill, sounds like it will work fine. Think I'm going to go look for a hammer drill now.
