I bought these to do some DIY projects around the house and cut some holes into a stone countertop for a faucet and soap dispenser. They cut through the stone with no problems at all. If I was cutting holes in stone every day a more expensive option might be worth it but occassional use these are great. Review: Great value and many different sizes are perfect for anybody wanting to drill holes in bottles. - Understand that these are all in metric sizes and this purchase was for the smaller sized bits. There are many sizes to choose from in this kit, from I think 3mm or 1/8 inch equivalent up to I think 24mm or like 7/8 inch. The sizes are laser etched on the shafts and are a little difficult to see, but the holes that they make are relatively smooth rather than just a sharp edge. The reason is that the bits are simply metal tubes that have one end dipped with metal covered crushed industrial diamond, much like sprinkles on an ice cream cone. With this said they are not lab quality sized bits, and have some cutting surface disparity due to the various sizes of chunks around the end, and this disparity will create a more rounded or smoother edge on the hole that you cut through the glass. Start out slow and at an angle with just the weight of the bit against the glass, and spin the bit against the glass until a little edge develops (I used a rechargeable drill), then add a few drops of water and start to reduce the angle and the edge starts forming a circle on the glass. Slow and steady wins the race!! This is glass, and super tiny pieces of glass are now being broken off of what ever you are drilling through so wear a mask, and have a removable work space that you can just wipe and clump up into a ball and throw away, like some damp newspaper that the wet paper will keep the super tiny glass fragments/shards from blowing away and you can just crumple up and throw away the mess with minimum wiping. With this set I managed to drill a 1/2 inch hole in the side of an aquarium for a water overflow, on one of those 2 1/2 gallon rectangle super thin glass aquariums with the black plastic frame, that still had some fish in it (do not recommend this). The hole was a success, the fitting has been installed and still the aquarium has fish in it (that suspect nothing.) Slow and Steady, listen to the screeching of the bit against the glass, if too much screeching you are either too fast or pushing too much. Slow down, add a few drops of water, and then continue on until you start to see the point where the water starts running down the glass on the other side, then slowly continue on until you have a hole drilled through whatever it was you were drilling. Note: I do not know what it would do to tempered glass, from what I know this would probably shatter any tempered glass the instant the bit scratched the surface. My use with these bits has been just plate glass and bottles. Good luck. ## Features - 12 PCS DIAMOND HOLE SAW DRILL BIT SET INCLUDES: 0.16β€œ/4mm(2pcs), 0.23β€œ/6mm, 0.31β€œ/8mm, 0.39β€œ/10mm, 0.47”/12mm, 0.55β€œ/14mm, 0.62”/16mm, 0.7β€œ/18mm, 0.78”/20mm, 0.86”/22mm, 1.18β€œ/30mm.

I would strongly advise if you do try it, use water to help with the friction. It says that you can use it on stone , gemstones, rocks, and pebbles. Hopefully that answers your question **Q: what is the chuck size 3/8 or 1/2 , I have 3/8 inch chuck?** A: I have a dewalt drill with 3/8 in chuck its perfect. **Q: What maximum thickness are these suitable for? What is the thickness of the diamond dust on the smallest three cutters?** A: I can't tell you in exact dimensions how thick the coating of the cutters are. I can tell you that I cut a hole through a substantial hi-power electrical insulator big enough to run a 120-v plug through. Before using these bits-nothing could touch the ceramics it was made of. The secret to success is to run water on the project while drilling. **Q: What machine can i buy for the drill bits?** A: and drill will work, cordless or corded ## Customer Reviews ### ⭐⭐⭐⭐⭐ Really good value for DIYer *by W***T on September 14, 2026* I don't know how long these will hold up but I will probably never know.

The variety of sizes in the pack is excellent, covering almost any small to medium hole you might need for bathroom fixtures or kitchen backsplashes. They cut through ceramic and glass cleanly as long as you use enough water to keep them cool. In terms of durability, they don't last very long. You might only get a couple of good holes out of each bit before the diamond coating starts to wear off. However, considering the very low price for a 15-piece set, I knew exactly what I was getting. It’s much cheaper to buy this entire pack and use them as 'disposables' than to buy one single professional bit that costs five times as much. If you are a professional contractor doing this every day, you might want something higher-end. But for a DIYer or someone with a one-time project, these are perfect. They are effective, affordable, and get the task done without breaking the bank. Just remember to use low speed and plenty of water, and they will serve you well for the price! ## Frequently Bought Together - 12 Pcs Diamond Drill Bits for Ceramic, Diamond Hole Saw Drill Bit Set Kit, Premium Glass Drill Bit for Bottles, Pots, Marble, Granite Stone, Tile Cutting 0.16 Inch - 1.18 Inch（4 mm - 30 mmοΌ‰ YLYL - 6 PCs Diamond Drill Bits Set for Porcelain, Ceramic, Glass & More - Versatile Tile Drill Bits for Efficient, Precise Drilling - Professional Masonry Drill Bit Set (10PCS) for Glass/Brick/Plastic/Cement/Wood/Tile/Etc, Industrial Strength Carbide Drill Bit Tip, 1/8"-1/2" by TITGGI --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.ec/products/448671560-12-pcs-diamond-drill-bits-hole-saw-for-glass-ceramic](https://www.desertcart.ec/products/448671560-12-pcs-diamond-drill-bits-hole-saw-for-glass-ceramic) --- *Product available on Desertcart Ecuador* *Store origin: EC* *Last updated: 2026-09-30*
