QEP 1-3/8 in. Pro Wet/Dry Diamond Hole Saw

Took about 10 minutes for each hole in ceramic tile, but it worked and that’s all that matters. Had to make a special trip because not every store has these in stock.

The drill cut really well and did not a walk

Did a great job on ceramic and porcelain tile.

I used this to drill holes through porcelain tile used on a shower wall. It would have been easier to use with a bit in the middle to serve as a pilot, but it still worked fine. I just put small piece of OSB behind it and it drilled through with no cracks to the porcelain.

This was easy too use. Just need too practice with it on some scrap pieces first. I would start at an angle and slowly move it to a straight position.

Excelent

Cuts like it’s supposed to it’s a really good unit hopefully I will get lots of cuts out of it

It got the job done perfectly.

Let’s not forget your not buying a boring machine so don’t expect this to act like one. This is the second one of these I’ve had and used up the first after numerous jobs. I drilled a hole just yesterday on some softer clay tile, but have used it one porcelain. Three key points: Start the cut at just the slightest of angles or it will want to walk on you, and use water to keep down the dust. Start the cut before using a lubricant as you will lose the friction of the initial groove and then when started just a little. Remember this is not a commercial billion dollar bit so go slow. It will cut just as fast and it won’t be so hard on your body. As in all diamond coated blades/bits they are only made for a limited amount of cuts so you’re not buying a bit that you think should last forever but it will be cheaper than marking your pieces and taking them to a masonry. A better bit than others of it’s kind I have bought over the years.

I spent an hour trying to drill a bunch of pilot holes / use a dremel to cut a hole in porcelein tile for a shower spout, but ultimately gave up and bought this thing which zipped through in 60 seconds.
