Bosch= Good Quality. ### ⭐⭐⭐⭐⭐ well worth paying a bit more for quality *by G***N on 6 May 2025* Normally use cheap drill bits but all the ones I had really struggled when drilling out a bolt. These ones made my life so much easier and saved me a lot of time. Always use a bit of cutting oil/spray when drilling metal and these are still sharp after use and hardly a scratch on them. --- ## 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/605936172-bosch-co2134b-7-64-in-x-2-5-8-in](https://www.desertcart.tn/products/605936172-bosch-co2134b-7-64-in-x-2-5-8-in) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-05-29*
