The item is more than capable of drilling into both metal materials with little effort. Amazing, will definitely buy more! ### ⭐⭐⭐⭐ Did the Job *by on Reviewed in the United Kingdom 12 August 2025* Happy with item, although one small point, the drawing shows 9.8mm diameter for the screw wafer head, the ones delivered were 10.4mm.. I chose these, as they needed to fit into a 10mm recessed diameter hole. A bit brute force and they went in. --- ## 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/378795074-4-2mm-x-25mm-pack-of-50-self-drilling-phillips](https://www.desertcart.sg/products/378795074-4-2mm-x-25mm-pack-of-50-self-drilling-phillips) --- *Product available on Desertcart Singapore* *Store origin: SG* *Last updated: 2026-09-21*
