These have smaller shafts than the traditional Dremel bits, which means you will use a different collet than the one Dremel tools usually have installed from the factory. Depending on your tool, you should have gotten more than one collet. Look at the accessories that came when you purchased your tool. If nothing else a quick Google search for Dremel collet will educate you on what needs to be done to make these bits work with your "Dremel" tool. As for these things... They are good you get a nice selection of sizes. What I really like is the smaller diameter bits .5 & .8 aren't blunt cut at the tip they come to a nice point. They are delicate don't try cutting through metal... Also if you wet them before each use it helps extend the life of the diamond coating. They aren't meant to last forever. They are best for detail work.... I would like to by the smaller ones in bulk. Unfortunately when looking to purchase these specific shapes in bulk I've had no success.... --- ## 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.sg/products/389739214-10-pcs-0-5mm-4mm-conical-expanding-hole-diamond-burr](https://www.desertcart.sg/products/389739214-10-pcs-0-5mm-4mm-conical-expanding-hole-diamond-burr) --- *Product available on Desertcart Singapore* *Store origin: SG* *Last updated: 2026-10-02*
