Diamond Drill Bits Set 10PCS, Glass Drill Bits for Drilling Holes in Glass，Procelain,Ceramic and Tile, Tile Drill Bit with 1/4 Inch Quick Change Hex Shank,3/16"-3/8"

Worked great for drilling small holes in stained glass.

Great product!! It had no problem drilling through the tiles in the shower to mount grab bars!!

I bought these to drill holes in my shells and they work very well.

Packaging is straight forward (NOT AMAZON) Drill bits in a plastic container. Container in a box (NOT AMAZON).I was needing to transplant some small plants into a couple ceramic pots, Hence the drill bits.Used a handheld drill. It probably would be better to have used a drill press instead.Drill bit did what it needed, which is not to crack or break the pot. Drilling from the outside in, the drill flaked on the inside but the exterior was well.I did not but would recommend using some lubricating oil to help keep the scale and make it easier for drilling. Currently have the hole clogged but not for long.Without the lubrication, it took a little while to cut through the ceramic pot but over all am happy

Worked perfectly

I drilled one hole used water to cool bit down then I started the second hole in ceramic tile the bit just twisted up and failed. This product should not have been made of alum...

You get what you pay for these days. Bought this set to drill mounting holes into tile above the fireplace to mount a TV. I did as the instruction suggested and started at a 45* angle before going straight into the tile. I constantly used water to cool/lube the bit as I drilled. Once I got to the largest diamond tip bit is where the quality came into question. The bits have a relief cut into the shank to allow debris to fall out while drilling. Turns out the larger sized bit warped while drilling into the tile. Luckily it was on the very last hole but the bit is now useless after enlarging four holes. I’ve yet to use the bits for brick and stone. They got the job done and cost a lot less than other bits.

Absolutely love these drill bits they are super easy to use and work like a charm. They aren’t super expensive like must others are and great quality.
