It did work well to get the bit started in the correct spots With out bit drifting around. But after awhile the sticky pieces would come loose from the tile or from the sticky tape. It then spun the whole thing dumping the water. So I used it at first then switched to spray bottle.

Was easy to work with if you read the instructions, but once we figured it out it worked great., was able to drill through the tile without any cracks or breaks, and only took a few seconds to complete hole.

Made 1/4″ sized holes in the tile that I had around my shower. Turned into a two person job with my wife refilling the water station while I held the drill in place. More messy than I had expected but what can you do when you HAVE to have a shower curtain in that exact spot. Great value and worked well, overall. Oh, the double sided sticky tape that is supposed to make a seal…doesn’t, especially after it gets wet.Don’t hesitate to use this drill bit, just be aware of the easily cleaned up mess afterward.

The water drain to fast out of the top cup and the drill cut to slow

The water system works good and the bit worked long enough to drill about 8 holes in my porcelain tile then broke in half. The shaft is slotted so be careful with how much pressure you use. It’ll do in a pinch but not as strong as a standard bit.

The guide allowed for a targeted stable drill point of contact. The water container was not utilized. Dipping into tuperware full of water often worked very well. Added hinges to install 3/8 inch glass shower door which weighed about 75 lbs.

This bit does the job but it’s not easy to use, the guides keep coming off and the stickies meant to keep everything from coming loose kept coming loose. Furthermore you have to keep on adding water to this tiny plastic container in order for the bit to work. When it ran out of water the bit bent.

My three stars are an average of the pros and cons of this hold saw. First, the pros: 1. if you need to drill a few holes in hard porcelain tile, you can spend a lot of money on useless carbide and/or diamond tipped drill bits before you figure out you need to use one of the hole saw bits, which can be very expensive (especially for a small job), but this one is inexpensive and worked just as well as the more expensive ones IF you keep it wet. 2. This is engineered to provide continuous water to the job when drilling into a wall tile, which is otherwise impossible (can’t use the putty ring, etc.)3. The initial cut into hard porcelain tile can skitter around with a guide, such as the one provided with this kit. Plus, the sticky holders allow you to handle your drill with two hands!Cons:1. This is SO cheaply made that it can break while just putting it together. Be careful.2. The water is supposed to slowly drip from the top container, but it drains too fast and dribbles down the wall (possibly removing marks you’ve made for other holes). Start at the bottom, and have a cup of water to replenish the reservoir, put a towel below it to catch the clayish water. 3. The bit will fill with ground up tile, so you have to use an allen wrench through the side slots to clear the build-up periodically to clear it. Don’t wait too long or it will reharden. So . . . I couldn’t have done the job without this kit, but it takes a bit of tweaking to make it work right. Unless you’re willing to invest in a more expensive saw bit, which don’t come with a guide or water well, and will wear out after a few holes anyway . . . save some money and be prepared by reading the suggestions in these reviews.

It’s a little messy but it certainly does the job.

This was far better than I expected. Had to drill porcelain tile and tried many nits, and this was only one that worked as advertised

Under all the gimicks of the plastic box and sticky pads is a diamond drill bit that worked just fine. I would have preferred to buy only that but they were out of stock so I bought this in store. Works just fine but the gimicks of the box and water and all that is not useful. The whole thing only works if you are drilling a hole into a wall as it uses gravity to dispense water and would just spill everywhere on a floor.Ended up throwing out everything but the double sided sticky pads and the bit.Would recommend buying just the bit rather than this whole kit.

It took some experimenting but here’s my advice. I had some very hard ceramic tile. Installing a shower door start at bottom hole and work up. Clean area with alcohol, then apply double sided sticker to tile and press firmly. Leave for a couple of minutes and then apply lower portion of jig to sticker. I kept a bottle of water hext to me to initially fill the upper water tray and to keep filling as needed. Run your drill at a slow speed (100 rpm).

It pretty much works like it says. The first few holes were pretty smooth. It seemed to get tougher as each hole was done. I was putting in a shower frame and I have to drill 4 holes on each jam. The part I did not like was after several holes I noticed that the shavings that come of during the drilling and fall into the little water reservoir stopped coming out. The drill was drilling much harder as well. I looked at the bit and all the debris was packing into the core of the bit. Once I got a small punch and cleared the drill bit core, it worked a lot better. Keep the core clean or it really slows down and packs in harder.

Great little tile drill, made nice clean holes. did exactly what it was supposed to. i was able to install pedestal sink as well as a shower stall no problem.

The bit was by far the best I have purchased for cutting through porcelain. I went through several bits and could only get a couple of holes drilled with them. Then I bought this one and it drilled nearly 50 more holes for me with ease. Be sure to keep the clean out washed out after every hole or else you will burn it up. The water flowing through the clean out is what keeps it from burning up.

Needed to drill holes in porcelain for shower curtain bar. This worked best to get the hole started. The water drains out of the top part pretty quickly and you have to take the whole thing off to empty the bottom part. I used it to just get the hole started, took the thing off the wall and continued to drill this time using a wet tile sponge to keep water dripping over the bit. Slow and steady is the way to go. Would use again.

The bit and watering mechanism were awesome for drilling precisely into Porcelain. Thank you so much.

We were almost finished with our bathroom remodel and realized a regular ceramic tile bit wouldn’t cut through the porcelain tile. It made installing the towel rack brackets a breeze! Thanks Home Depot for carrying this product in stock!
