Take your Dremmel tool and the bit you want to use to Lows. The salesman will help you buy the collet that you need **Q: I am looking for diamond bits to drill holes in 6mm glass for jewelry. Would these work?** A: tThey are awesome, one trick to keep them from over heating and dulling, find u a stainless steel pan cover what u r drilling with water, then drill. the drill bits will last a long time, i have used them on steel when i make weapons to,water keeps them cooled down. they are a great set of bits. **Q: Do these work with a dremel tool? Some of them look very small.** A: The two larger bits do fit my old Dremel with a smaller chuck. The 1.5 mm fits the chuck on my drill press. Alas, the 1 mm needs a small chuck and the two I have bought from Amazon are tedious to align and do not work very well. Frankly, you would probably promptly break both the 1.5 and 1 mm in a Dremel because they are so delicate and need precise alignment for drilling. I have used all the bits with a drill press (with PLENTY of water and SLOOOW pressure) and they work great. One broke simply because I moved the vise and snapped it off. I broke a 2 mm, but simply used the broken bit for another bunch of holes. Broke again and I am now using a stub and it works just fine. Obviously, not deep holes! Drilling on polished rocks of different varieties. Work great. **Q: Need to drill 30 screw holes in plexiglass and Lexan panels, will the bit last through 30 holes and do I need to cool bit while using?** A: You're better off with regular drill bits you wouldn't want to use this type of drill bit with diamond bits it will cause additional heat and melt the plastic vs. drill through cleanly. These are a very abrasive way of drilling and only used for masonry or actual glass. ## Frequently Bought Together - Drilax 1mm 1.5mm 2mm 2.5mm Diamond Drill Bits for Stones, Sea Glass, Seashells Compatible with Dremel - 4 Collets Included 24 Pc Set - Dremel Drill Press Rotary Tool Workstation Stand with Wrench - Mini Portable Press & Tool Holder - 2 Inch Depth- Ideal for Drilling Perpendicular and Angled Holes - 220-01 - Drilax 1mm 2mm 3mm Diamond Drill Bits for Glass, Stone, Sea Glass, Shells, Jewelry Making, Gemstones - 30pc Mix Set Compatible with Dremel Standard Shank --- ## 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.tn/products/782624964-assorted-pack-of-20pcs-4-sizes-1mm-1-5mm-2mm](https://www.desertcart.tn/products/782624964-assorted-pack-of-20pcs-4-sizes-1mm-1-5mm-2mm) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-09-03*
