Diamond Drill Bits Set, 10 PCS Diamond Hole Saw Set, Glass Drill Bit for Ceramic Tile Porcelain Marble Granite Stone Bottles

Why I didn’t think about this before? Would have saved me a ton of trouble. This is now a life changer for sure. Works like a CHARM. I attempted to make holes on ceramic vase with this tool, and it just works wonderfully. Definitely recommended to use running water, set up bit at an angle and slowly drill until you get a purchase. Once you see the indentation, speed up your drill and gently allow the tool to cut. Does a nice smooth job. Very pleased. Took me literally two minutes to make a nice hole.

Needed to drill hole for RO system. Heated one time. Use store ones for over $35 a piece. This one worked great

Great product for the price! Does it job well. I use it to drill holes on vases.

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.

Worked great to make holes in my plant pots, just be patient

This work however it is easily broken

Hi, this is Lumpy once again with a review of the Diamond Drill Bits Set. I was able to use the bits over the weekend cutting into ceramic plates in order to make a kitchen clock. I drilled without any issues into the ceramic plate, set my battery clock, and now just need to attach the kitchen tool items(miniature) that reflect the hour for the clock. I used a spoon for 1 O'clock, an apple for 2 O'clock ect. These Bits are a must!

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.
