Drilax 4-1/2" Diamond Hole Saw with Guide | Tile Cutter for Porcelain, Ceramic & Glass | Granite & Stone Hole Saw for Large Drains, Recessed Lights & HVAC

Make sure to clamp the tile and guide down lightly and start slow. Once line is established run your drill or grinder at 2000 rpm's. It will take about one minute. Use very little pressure and keep filling the guide with water. Check when you hear chalkboard sounds. All in all it is a pretty fast process. I will buy again for sure!Thank you

Works great up to now that is.

It performed just as advertised. Worked great cutting porcelain tile for my bathroom showers.

Works great

As my Amazon user name may suggest, I work as an installer of ceramic tile and stone. I have been fortunate enough in recent years to work with many clients specifying high end materials in large scale custom installations. More and more, these jobs entail the use of large format porcelain ceramic floor and wall tiles. I love the look of these behemoth tiles (commonly 12 x 24 or larger) but they certainly present some challenges when striving for a neat, clean installation.The job I am currently finishing is a good example of these challenges, as the design features 12 x 24 shower walls in two showers with large, custom niches in both. Heavy gauge (3/8") tiles of this size can be very tough to work with, due in large part to the internal stresses which accumulate within the tiles themselves as they are double fired. Attempting to cut anywhere near the edges very often ends in failure as the internal stresses relieve themselves with a sudden, uncontrolled crack. Even harder still is the job of cutting a large diameter hole to accommodate a shower control valve.I have always used a 4" diamond edged wheel in an angle grinder to make these cutouts in the past. I've had instances where I've had two or three tiles break before I have finally gotten the piece right. That can get expensive, and I have adopted the policy of not making any more than three attempts without at least taking a break and/ or trying something different. On this particular job, after breaking a record four tiles attempting to make that large hole, I looked online for an alternative.This 4 1/2" hole saw is exactly the right diameter to accommodate the shower valve seal that comes with the Schluter Shower System, which I try to use in every shower I do. It came in two days, and the price was significantly less than I pay for similar bits of much lesser diameter. I was skeptical.I am very practiced in using hole saws in tile, so the set up for me was easy. There is no central pilot drill in these bits, so one must use other methods to keep the bit from wandering whilst starting the hole. You also must use a low RPM drill and keep the work and the bit wet. Go slowly.Long story short....it worked flawlessly on the very first attempt. Neat edged hole through rock hard porcelain tile very near to the edge of a 12 x 24 tile.Highly recommended.

Having to cut through porcelain was a bit intimidating but we knew it had to be done. I wasn't happy about having to pay this much for a bit we would probably only use once or twice but we didn't have much choice if we wanted the job done right. I wasn't familiar with this brand for tools either and I know that sometimes things on Amazon are hit and miss as far as quality goes. However, I'm so glad we selected this one. It worked great. The template is used not only to keep you centered but also worked to hold the water in. Don't forget the water - my husband almost did by the time he got a base set up for the bit to drop through. As others have said, be patient and don't force the bit through the tile.

The cut should speak for itself. I believe this tool did a great job on the first try. I have never used this brand before but I will keep it in mind from now on for future projects.I would have only one suggestion forthe company, the foam was good for holding the tool but it can be improved. I will be 3d printing one that is a little more steady and easier to hold the bit.Overall, great job and thank you for making my life easier!!

I ordered this item as another reviewer had said they had used it to cut tile for their shower mixer that had a Schluter seal; exactly my situation.I am tiling with 12" x 24" tiles and where the mixer was set spanned two tiles - just barely - you can see in the picture. I used a scrap of 1" plywood to make a guide by tracing around the edge of the drill bit and then using a jigsaw to cut out the circle (used a drill to make the initial hole). I then set up the two tiles using tile spacers and plumbers putty in what will be the grout line. I used more putty to secure the wood guide to the tile, and then duck taped it down as well. I filled the guide with water and started drilling. I made the guide just a hair too large so the drill was not as steady as I would have liked - I think that's where the chip you can see in the photo came from. Also because of the grout line - even though I had the plumbers putty - the water leaked out and so I ended up using a pitcher of water and pouring it while I drilled.I'm thrilled with the result. Had used an angle grinder for around the toilet and this was leagues easier and did a much better job.

Great product, great service.

Very for my job
