Oudtinx Diamond Drill Bit Set, 10 PCS Glass Hole Saw for Tiles Glass Ceramic Marble Bottles DIY,6mm - 50mm

This whole set cost less than 1 big brand cutter. Ok not as durable but fine for the odd time you need them.Use at low speed setting on drill and plenty of water. Used a fair bit now and showing no wear.

The quality is basic, be careful as the table I the image shows larger sizes than available, this misleading information led to an erroneous purchase, luckily I was able to enlarge a hole in a ceramic sink, more by using the sides and cutting at an angle to create a whole a Mil or so larger than the 3mm.Advertisers should take care when showing images to show true data. The written text is correct, just the image which people refer to gives information about a product size not available in that purchase.The shaft broke away from the body, probably as a result of my using the sides to grind, but with little force, I noted they are weak spot welds .Given the quantity, the price is acceptable, I have marked down given quality, including a misleading table of sizes.They do work but I would consider them to only have a limited lifespan.

I bought these with the hope I could complete a craft protect. They are easy to fit and easy to use but we’re not as sharp as I expected and blunted quickly. Probably ok for smaller projects.

All right I guess to use a few times and throw away, if you are a proffesional you would buy more expensive ones but I am satisfied so would recommend for occasional use any day.

Really good for drilling holes in glass bottles.

Good value if you are only drilling ceramic tiles.

They did what I wanted of them, if you want them to drill more than half a dozen holes look for better quality

Great on ceramic tiles
