I needed to buy the referenced adapter to fit this in my drill chuck (as opposed to the native angle grinder connection). Worked great. Take your time - I counted to 10 during active drilling, and then paused to let things cool.To start I suggest masking tape and marking your hole location. Start the drill at an angle, and the tape will help prevent the bit from walking. Keep with water on the area while drilling too. ### ⭐⭐⭐⭐ 4.0 out of 5 stars drills through a concrete block like *by B***R on Reviewed in the United States on October 27, 2015* Wow ,,drills through a concrete block like butter ### ⭐ 1.0 out of 5 stars the second picture shown is not what comes in the ... *by A***N on Reviewed in the United States on November 22, 2014* the second picture shown is not what comes in the box. There is no drill adapter. This is the second one I have ordered and the pictures are misleading. Do not buy unless you have a core drill adapter already. see pictures below... --- ## 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.vu/products/31271466-apexx-22101-02037-bluecore-drill-bit-for-granite-marble-limestone](https://www.desertcart.vu/products/31271466-apexx-22101-02037-bluecore-drill-bit-for-granite-marble-limestone) --- *Product available on Desertcart Vanuatu* *Store origin: VU* *Last updated: 2026-05-02*
