I would also think this would work for other tools that are used on common die grinders. It was easy to install, and easy to remove. Overall would recommend. It has a black coating that did not chip or peel during my testing. ## Frequently Bought Together - DaduoRi 1-1/4"-7 Female to 5/8"-11 Male Thread Core Drill Bit Adapter for Concrete Coring Drill, Convenient Converter, Premium 1-1/4-7 Inner Female to 5/8-11 Outter Male Thread - DaduoRi 1 1/2 Inch Wet Core Drill Bit, 1.5" Core Bits for Concrete, 14" Drilling Depth, 1-1/4"-7 Thread Diamond Core Drill for Cured Concrete, Hard Masonry, Brick, Solid Cement, Stucco, Stone (38mm) - 5" Diamond Core Drill Bit with 17.7inch Total Length, 1-1/4"-7 Thread, Laser-Welded Segments for High-Performance Drilling Cured Concrete, Brick, Stone, Masonry Walls and Floor --- ## 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.vn/products/652684167-1-1-4-7-female-to-5-8-11-male](https://www.desertcart.vn/products/652684167-1-1-4-7-female-to-5-8-11-male) --- *Product available on Desertcart Vietnam* *Store origin: VN* *Last updated: 2026-05-19*
