I used about 3-4 of these per year, sometimes I let my helpers use itThey tend to “learn” by burning the tool up….keep it wet, and let the tool do the work, it works finelet it dry out, or horse the tool around too much and you will cook it quickly

Let me say that the diamond drill was excellent, but I had never used one before. I was drilling porcelain tile. The 45 degree starting angle was tricky for me. But it was my inexperience, not the drill. The drill does a great job. It is not recommended to drill very deep, maybe a 1/2″ total. Do keep it watered while drilling to keep it cool.

I went through 2 other diamond bits trying to drill a single hole in porcelain tile—until I finally bought this bit. Just move the bit around in a small circular motion—and it will work itself through in no time. Very satisfied.

This was just what I was looking for to drill through ceramic tile to anchor shower rod. Highly recommend this product.

I was so scared that I would crack my ceramic tile when making holes to mount the grab bar in my shower. This little blue colored diamond hole saw made my fears go away. You use it like any other drill bit in your drill. However, you dip it it he tip in water before starting and about every 5 seconds while drilling through the tile. No need for running water for cooling. The tip is held at an angle to get the first little cut in the tile. Once you have that, it will keep the hole saw from slipping and scratching the tile. Then you can drill at the customary 90 degrees., perpendicular to the tile. Use light pressure while gently oscillating the drill while it is making the hole. You’ll need to dip the saw tip in water every 5 seconds to cool things down. This works and doesn’t crack the tile.

Used this on porcelain tile, found the right speed was not to fast. Cleaning it out could be easier.

One of the toughest jobs to do is drill a straight clean hole in your ceramic tile. If you’re installing a new shower door or a shelf in the shower, this bit is what you need to get the job done. The diamond chips make cutting through the glaze layer very easy. Important to follow the instructions carefully. Holding the bit at an angle to get started takes some practice, but once you start through the glaze, ease up to perpendicular and you’re home free. A helpful tip, I take an old sponge put a hole in it, soak up some water. Once I start drilling I slip the bit through the hole in the sponge and use the water to keep the bit cool. This will extend the bit life. Once through the glaze layer the bit goes through very easily. You’ll have a nice clean hole to put your anchors in.

the better grade hole saw was worth the money but the cheaper one didn”t even drill one hole before it was burnt out

Great quality. Good price. Cuts through both the plastic surround and the ceramic tile behind it, to mount the shower hangers.

Took a little longer to get through porcelain than I thought it would. However, it didn’t wander like mason bits once it gets started. The first QEP diamond bit I tried was the one that came in the kit that had the reservoir for wet drilling. The diamond tip disintegrated within 10 seconds leaving a beautiful sparkling mess.

The QEP 1/4 in. Pro Wet/Dry Diamond Drill Bit has a small cylindrical stem 2-1/4 inch long. On one end around the edge is a brazed diamond coating that cuts through porcelain, ceramic and glass. They recommend a quick dip in water before starting to increase the bits durability and to dissipate heat. First start at a 45 degree tilt until scoring the material and move to finish the cut at 90 degrees using high RPM. It seemed simple enough so I tried it first on a test tile. The drill seems to cut in a deliberate fashion at its own rate. It makes a small doughnut around the circumference of the hole and the center material goes into the center of the cylindrical drill stem and later pops out. It made easy work of the tile and cut a clean hole. This is a good drill to have in cutting screw holes for mounting fixtures such as towel racks to a tile wall.

Bought a couple bits expecting trouble. Used the guide and this bit to cut porceline very nicely. (It was a “made in UK bit.) The china one wouldn’t scratch the tile though.
