You will need a large 3/4" drill and an 5/8 arbor. I wouldn't recommend it. **Q: do they make these to fit the 7 inch dewalt angle grinder?** A: Yes. When the 4 inch was too small for my project I purchased a 7 inch grinder, grinding wheel, and shroud through amazon. The 7 equipment is a significantly larger investment than the 4 1/2. 7 inch equipment: Grinder - DWE4557, floor grinding wheel - DW4775, and shroud DWE46170. **Q: Has anyone used this with the herzo dust shroud? I had issues with another disc being too shallow for the dust shroud so im looking for a different di** A: I had no problem **Q: Will this grinding wheel grind down a high spot pushed up by roots on my driveway? I have a raised section about 3/4” high causing a tripping hazard.** A: We recommend our 4-1/2" double row diamond cup grinding wheel for dry grinding of concrete and other masonry materials. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Good *by S***. on 12 June 2025* ### ⭐⭐⭐⭐⭐ Great Product *by E***K on 22 December 2021* ### ⭐⭐⭐⭐⭐ #1 *by M***. on 5 April 2021* DE LO MEJOR Y ME A DURADO , TRABAJE EN UN PISO DE 50 METROS CUADRADOS Y SE GASTO EL 30% MUY BIEN ## Frequently Bought Together - DEWALT Grinding Wheel, Double Row, Diamond Cup, 4-1/2-Inch (DW4774) - DEWALT Concrete Surface Grinder Kit, 5-Inch (DWE46253) - DEWALT DW4777T 5-Inch XP Turbo Diamond Cup Wheel --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.id/products/335941356-dewalt-grinding-wheel-double-row-diamond-cup-4-1-2](https://www.desertcart.id/products/335941356-dewalt-grinding-wheel-double-row-diamond-cup-4-1-2) --- *Product available on Desertcart Indonesia* *Store origin: ID* *Last updated: 2026-04-24*
