The 3-1/4" will work perfectly in the 3-1/8" bore as the 3-1/4" Flex-hones working range is down to 3.000". Thank you for the inquiry. **Q: Can i use this to hone out an old cast iron pipe? it's about 3 3/4" now and i want it at 4" id. thanks** A: This hone is not coarse enough to remove that much material. It would take forever and the hone would wear out first. You would need a lathe to remove that amount of thickness. **Q: I see that it says tool is oversized. For a cylinder bore of 3.66, should I be getting the 3.75 or the 3.50 model?** A: 1I bought a 4.50 and used it on a 3.55 bore with no problem I didn't hone as much as instruction said for large bore, hatch marks were beautiful so go bigger and you can use it over a broad area of bores. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Five Stars *by on Reviewed in the United States 15 February 2016* Awesome item thank you ## Frequently Bought Together - Brush Research GB45812 FLEX-HONE®, 4-5/8" (117mm) Diameter, 120 Grit, Silicon Carbide, For Mild Steel, Stainless Steel, Cast Iron and Softer Ferrous Materials - Brush Research FHG FLEX-HONE® Oil, Specially Formulated Honing Oil, 1 Gallon Bottle (128 fl oz) - Permatex 81950 Ultra Slick Engine Assembly Lube, 4 oz. , Red --- ## 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.fr/products/364481236-flex-hone-tool-brush-research-flex-hone-cylinder-hone-gb](https://www.desertcart.fr/products/364481236-flex-hone-tool-brush-research-flex-hone-cylinder-hone-gb) --- *Product available on Desertcart France* *Store origin: FR* *Last updated: 2026-09-13*
