Will it fit in a standard pin vise?** A: Diameter of the shaft is 1/8" or .125 **Q: Can I put these in a dremel tool?** A: Absolutely, but you have to remember these are extremely brittle. ANY side force will break the bit. You are best served using them in some sort of press but with very steady hands and a thoughtful method, operating by hand is possible. **Q: can these be use by hand twisting on brass jets in carburetors to enlarge the one increiment at a time?** A: I'm going to say yes. I twist them by hand, but I should also mention that I'm drilling into wood. I build model ships. Drilling into brass might be possible, but be aware that these bits, although very effective drilling into wood, are very brittle. I can't tell you how many have snapped on me when I least suspect it and I have to break out another set. I've learned to drill carefully and with patience. Other than that, I do like these bits and have started using them in my Dremel. **Q: Are these recommended for drilling into raw semi-precious stones (like Crystal Quartz, amethyst, agate etc) for the purpose of creating pendant holes?** A: No. You really need a diamond bit or hole saw, depending on the size. You'll also want to have a water drip going or at least use some sort of lubricant such as beeswax or gem lube. ## Frequently Bought Together - WayinTop 50pcs PCB Drill Bits Set Spiral Flute Carbide 0.3mm-1.2mm for Print Circuit Board Stone Dremel Jewelry CNC Engraving (5PCS Each) - Mudder 57 Pieces Hand Drill Bits Set, 46 Pcs Pin Vise Micro Twist Drills and 10 Pcs PCB Mini Cutting Bits for Resin Polymer Clay Craft DIY Jewelry(0.1-1mm,Random Color PCB Drill) - 0.3-1.6 mm Micro Mini Drill Bit Set Tiny Drill Bits Small Shank Full-Ground HSS Twist Drill High Speed Steel Boards Tiny Drill Bits for Dill (40 Pieces) --- ## 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.be/products/564080750-50pcs-pcb-drill-bits-set-spiral-flute-carbide-0-3mm](https://www.desertcart.be/products/564080750-50pcs-pcb-drill-bits-set-spiral-flute-carbide-0-3mm) --- *Product available on Desertcart Belgium* *Store origin: BE* *Last updated: 2026-09-22*
