It was well worth the price and did just as good a job as others costing 4X the price. I can't say how it would do on hard steel or other similar tough metals since I haven't tried it on them. ## Frequently Bought Together - NEIKO 10185A Titanium Step Drill Bit, High-Speed Alloy-Steel Bit, Hole Expander for Wood and Metal, 12 Step Sizes from 3/16 Inch to 7/8 Inch - RAINPAL RBS005 Brass Water Container/Rain Barrel Quarter Turn Spigot(LF Compliant, For OPEN TOP BARRELS) - Owl Focus 37.5 Inch Mesh Cover for Rain Barrel,Rain Bucket Leaf Filter Screen Cover --- ## 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.sn/products/246314670-10185a-titanium-step-drill-bit-high-speed-alloy-steel-bit](https://www.desertcart.sn/products/246314670-10185a-titanium-step-drill-bit-high-speed-alloy-steel-bit) --- *Product available on Desertcart Senegal* *Store origin: SN* *Last updated: 2026-10-03*
