Thicken corundum coating on the tops offers superior cutting strength for maximum drilling outcomes.Extraordinarily Sharp Each diamond drill bit was processed by a smooth and exact finish that lower the incision resistance and drill pressure, increase the sharpness and the use of water lubrication. Excellent for making clean and precise hole on glass or ceramic and considerably extending drill bit life.Large Clearance Hole These ceramic drill bits along with large clearance hole facilitate the entrance of cooling water and escape of chips. Making the drilling process more easy and relax.Widely Application There are 5 different sizes included with this glass drill set to meet various demands. Perfect for drilling glass, tile bottles, blocks jars, fiber glass porcelain tile ceramic, vitrified, brick and stone. 5 Sizes Each drill bit set includes: 4mm/0.16", 6mm/0.24", 8mm/0.31", 10mm/0.4", 12mm/0.47" Total length: about 2".Package Contains 5pcs* Diamond Coated Drill BitAttention: Please keep the speed within 800-1000 per minute, low drill pressure and increased use of water lubrication will extend drill bit life. And please keep adding water when the diamond drill bits are working on the glass or ceramics. Review: They either need a drill press or have something with a hole the same diameter that it passes through as a guide. like a little wood block with a predrilled hole stuck to the glass so it doesn't slide around. They have no pint and rather cuts a little circle out like a hole puncher. A guide that is water fill-able gives the bits a little longevity. without cooling they last about 2 holes. With water they seem to last a long time. They should come with a predrilled plastic block with different sized holes and double sided adhesive tape to stick it where the hole is needed. I'd give them a 5 if they came with that. That makes them last as one can then wet drill. Review: If you are trying to drill a glazed pot, angle the bit to rough up the surface where you intend to put a hole, otherwise if you try to drill straight down the bit slides all over (for me it did, anyway). And it really took what seemed to be a loooong time and lots of pressure to make a hole all the way through. Hope it goes better for you! ## Features - 【EXTREME HARD 】These diamond drill bits are made of industrial grade carbon steel with nickel-plated coated body to resist corrosion.

The diamond drill bits are compatible with most drills Warmest regards, StarQualityBargain Team **Q: Why are these called "diamond hole saws" if they are made of corundum? corundum is not diamond.** A: Thank you for inquiry.

And it really took what seemed to be a loooong time and lots of pressure to make a hole all the way through. Hope it goes better for you! ### ⭐⭐⭐⭐⭐ Review *by E***D on 25 September 2022* These are awesome. As other reviews have mentioned, put a little water on your drilling surface, start drilling at a slight angle, and PRESS DOWN. You also have to start the drill BEFORE you press into the surface of whatever you’re drilling (not like driving a screw, where you touch the screw head first, then start the drill). Made perfect drainage holes in a number of ceramic pieces I can now use as planters. --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.dk/products/541128496-glass-drill-bit-set-5-pcs-diamond-drill-bits-hole](https://www.desertcart.dk/products/541128496-glass-drill-bit-set-5-pcs-diamond-drill-bits-hole) --- *Product available on Desertcart Denmark* *Store origin: DK* *Last updated: 2026-04-27*
