Diamond Drill Bits Set 10 PCS Diamond Hole Saw Set Glass Drill Bit for Ceramic Tile Porcelain Marble

Worked very well for my needs. I'm sure there are better bits out there, however, for the price point and quick delivery you can't go wrong. I drilled holes into stones to make drawer pulls on a shop bench. Worked great! Would recommend this product. Read more

I bought these drill bits to add drainage holes to a small collection of ceramic and clay pots that I've accumulated over the years. Some are small - think 2" individual cacti and succulent pots-- a few in the 8-10'" range, and one 16" monster with walls an inch thick. I'm happy to report that all now have cleanly cut drainage holes, and that it took no more than a minute each for all but the big one, which nonetheless took only a few minutes with the one inch bit. It's crucial to follow the two pictographic instructions: 1) Start the hole with the bit at a 45 degree angle to the work surface and once it "bites" return to 90 degrees, and 2) keep the bit wet. When first starting, keep the drill speed low, and use both hands to hold it in place, as the bit will want to walk. I gave these 3 stars in the durability category only because while the 1" bit did its job, it is now completely worn out and in the trash. That said, these are inexpensive, they work just fine for my needs, and I wouldn't hesitate to buy them again. Read more

Top quality and a great design. I was able to use them in both my cordless and corded drills with ease. I used them to drill holes in acrylic and glass wall cubes from the 70's to put lights inside them for Halloween and Christmas decorations. Multiple sizes for multiple projects. I bought more sets as gifts for Christmas this year for other do it yourselfers as they are a great value for the money. Read more

The great advantage, and only use, of these bits is to cut holes in glass. I use them to drill holes in containers to make transparent orchid pots out of old/cheap glass containers. The thing you need to know is that they require a guide to get started, and you have to keep the bits and surface cool while using them. Guidance is most easily achieved by drilling a hole in a piece of wood first with a conventional bit, then putting the wood on your glass where you want to do the cutting. To keep the bits cool you can set up a water drip, My preferred method is to drill under water. Put the glass you're drilling in a bucket fill to 1/2 inch or so above your object, and start drilling. Ideally, keep object full of water as well. Drilling rigid materials under water helps to reduce the possibility of cracking. Read more

The drill bits work fine for small jobs and soft materials like ceramic or glass. There are many sizes in the set, which is nice. But they don’t last long — some bits got dull after just a few uses. They also heat up fast if you don’t use water. Overall, it’s an average product. Good for light work, but not for heavy or frequent use. Read more

Work very well. Read more
