Excellent product, much easier to use than a conventional 'spade' tile bit
This QEP drill bit is very easy to control when positioning the bit to start the hole in the tile, drills clean holes and seems to be a lot more durable than conventional 'spade' shaped tile bits I have used. Drilling into tile can be laborious and also risky in as much as you can damage the tile if the drill bit skids over the tile surface when starting the hole however these bits are a real confidence builder in this respect. Its the first time I've tried one of these and I would highly recommend it. We recently installed a small grab handle in our bathroom to make it safer to get in and out of our deep soaker tub. We remodeled our bathroom recently and put some 1/4" thick ceramic tile over 1/2" cement board. I previously used a more conventional spade shaped tile drill to drill holes for our shower door and was looking for an alternative that is easier to control and more durable than a spade bit. This QEP bit is very easy to use if you follow the very simple instructions. Have a small bowl of water handy to keep dipping the drill bit in to keep it cool and lubricated and you will have no issues. To start drilling a hole, you angle the bit at 45 degrees and have the drill on full speed before contacting the tile. A firm grip will stop the drill from skating over the tile and after a few seconds you can change the drill angle to be square to the tile and drill the hole conventionally. Every few seconds you should take the bit out of the hole and dip it in water to keep it lubricated and cooled. In my case, if it dried out, a puff of tile dust would be forced out of the hole letting me know it was time to dip the bit into the water. I drilled 5 holes and the fifth was as easy to drill as the first so the drill is certainly durable. By comparison I obliterated a spade tile bit after a couple of holes when hanging the shower door in the same ceramic tile a few months ago. Between each hole, I used a smaller drill bit to clean out the tile residue from the inside of the tile bit. This stopped the center of the drill plugging up with the tile and backer board core it was removing. I also found that the bit was less prone to 'wandering' and gave straight, true holes when the bit was progressing through the different material in the hole. When I was drilling with the spade bit, I found it would go awry when I made it through the tile and into the cement backer board and I had no such issues with this QEP drill bit.

Excellent bit!
I got one of these because am doing a bathroom reno using travertine tile from the floor to the ceiling. So in need of something to drill holes for passing electrical wiring through and such, and this little guy works quite well. You have to follow the instructions however and come in at an angle very delicately to start your groove cut or the bit will dance all over your tile.

        The diamond bits wore off before I could get halfway through the first hole I drilled. Total waste of money.

        Used to drill through porcelain title with no problems. Basic masonry bits would not even scratch the porcelain. You MUST Keep the bit wet while drilling, so stop every 20 seconds. Take your time. Strart holding the drill at a 45 degrees and then very slowly turn to 90 degrees. Don’t move past 45 degrees until the bit has dug in at least a 16th of an inch. I had no problems and the bit is still in good shape after 8 holes.

        Not Recommended!!!
        Could not give zero stars, so I picked lowest possible rating. This bit wil not stay in place when starting the hole. Unless you plan to use a drillpress, which seems unlikely, I’d steer clear. Just my thoughts on this product. Hope it helps someone else save $10-$15.

          Perfect and long lasting
          I tried all other hole saw I had and nothing worked on my ceramic which had a high density. I was afraid of the comments saying it doest last long or works for only 5-6 holes... Let me share.my experience: I did 21 holes in a very hard ceramic and it's still working like a charm. I believe people saying it doesn't last long did not read the instructions of the hole saw. You have to pour it in water every 5 seconds. Personally I did every 3 seconds to make sure it lasts longer after seeing the comments. I bought 2 of this item because I though it wouldn't last long enough, but surprise, it did very well! I'm returning the second hole saw.

            Bought this item to drill through porcelain tile for bolt holes for deck rail posts. It didn't drill through the tile so I tried some other bits. Masonry bits did not work but there is a pointed bit from Ryobi that did the job. Each post had four bolt holes so I had quite a few holes to drill.

            Cheaper hole saws gave out after 2 porcelain holes. This PRO version is the way to go. Don't buy cheap hole saws - they will waste your time and money.

            It cuts ceramic but walks without a pilot hole. It is a hollow tube, so maybe there was an center point arbor that I was missing. Overall, until I resole the walking issue won't be using them.
