Does what it should and seems to be a long lasting product! ### ⭐⭐⭐⭐⭐ Review *by V***N on 13 April 2026* Ok ### ⭐⭐⭐⭐⭐ Review *by H***N on 31 December 2025* I needed to slightly enlarge the 1 inch hole of a cast iron barbell weight plate that wont accept my 1 inch barbell. I was only using the last level (1-1/8 inch) of this bit to take off maybe a half-millimeter. After about 15 minutes, this bit was able to grind through about half the plate's thickness before the bit no longer had any bite. Afterwards I used a 1 inch flapper wheel abrasive grinder which smoothed the cut edge but it would take many wheels and hours to only use that to grind out the hole, and likely burn out my hammer drill. A half-round file was too big to file out the hole. Otherwise, I bet this bit does a great job on steel, just not cast iron which is asking too much. ## 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.it/products/407124632-10185a-step-drill-bit-for-metal-3-16-to-7](https://www.desertcart.it/products/407124632-10185a-step-drill-bit-for-metal-3-16-to-7) --- *Product available on Desertcart Italy* *Store origin: IT* *Last updated: 2026-09-24*
