I've missed the return time as I didn't use them for a while. Only one of them is good , other two either not fit in or fall down of the impact driver. ### ⭐⭐ not very impressed *by C***N on Reviewed in the United Kingdom on 22 April 2020* ok if you want to drill plastic or wood...worked ok first time cutting 3mm plate then went blunt. you get what you pay for. ### ⭐⭐⭐⭐⭐ CUmplen *by J***S on Reviewed in Spain on 14 April 2020* Buena relación calidad precio, el estuche está muy bien.Las he usado para taladrar acero inoxidable AIS316, que es un material muy duro y complicado de taladrar y han respondido mejor de lo que esperaba. --- ## 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/131269384-step-drill-bit-set-high-speed-steel-titanium-coated-spiral](https://www.desertcart.be/products/131269384-step-drill-bit-set-high-speed-steel-titanium-coated-spiral) --- *Product available on Desertcart Belgium* *Store origin: BE* *Last updated: 2026-10-24*
