Review: Does the job - I got this to remove thin set in a small area where i was changing tile. It worked very well and got down to the concrete quickly. I would not recommend using it indoors without a dust shroud and vacuum attached, and if you are using it outdoors, you should wear a mask at the very least. I did manage to create a couple of crescent shaped gouges in my slab, but since I'll be tiling over them it doesn't matter. Review: Good - Seems like it will last a good while before wearing. ## Features - Extended performance diamond matrix provides 350x's the life of conventional abrasives and aggessive material removal - Large Grinding segments with heat treated steel bodies which provides increased durability and wheel life - 4-1/2-inch wheel with 5/8-11 arbor - Ideal for dry grinding concrete and other masonry products - Double rim provides longer life and more aggressive material removal ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B003XXE0RA | | Best Sellers Rank | #147,049 in Tools & Home Improvement ( See Top 100 in Tools & Home Improvement ) #180 in Diamond Blades | | Brand | DEWALT | | Brand Name | DEWALT | | Compatible Devices | Angle Grinder | | Compatible Disc Grinder Tool Models | DEWALT DCG416B | | Compatible Material | Concrete, stone, metal | | Compatible devices | Angle Grinder | | Construction Type | Super-Abrasive | | Country Of Origin | China | | Customer Reviews | 4.7 out of 5 stars 1,736 Reviews | | Global Trade Identification Number | 00028877588773 | | Grit Material Type | Diamond | | Grit Number | 36.0 | | Grit Type | Coarse | | Grit material | Diamond | | Grit number | 36.0 | | Grit type | Coarse | | Housing Material | Steel | | Included Components | 4-1/2IN DBL ROW DIAMOND CUP WHEEL | | Industry Standard Identifier | DW4774 | | Item Diameter | 4.5 Inches | | Item Dimensions | 12.7 x 11.4 x 10.2 centimeters | | Item Dimensions L x W | 11.4L x 11.4W centimeters | | Item Type Name | Dewalt - DW4774 | | Item Weight | 0.45 Kilograms | | Manufacturer | Stanley Black and Decker | | Material Type | Blend | | Maximum Rotational Speed | 350 RPM | | Model | DW4774 | | Number of Items | 1 | | Number of Packs | 1 | | Part Number | DW4774 | | Product dimensions | 11.4L x 11.4W centimeters | | Recommended Uses For Product | Grinding | | UPC | 028877588773 | | Unit Count | 1 Count | | Warranty Description | 30 Day Money Back Guarantee | ## Product Details - **Grit material:** Diamond - **Product dimensions:** 11.4L x 11.4W centimeters - **Brand:** DEWALT - **Compatible devices:** Angle Grinder - **Grit type:** Coarse ## Images ![DEWALT Grinding Wheel, Double Row, Diamond Cup, 4-1/2-Inch (DW4774) - Image 1](https://m.media-amazon.com/images/I/71OF0-jmb7L.jpg) ![DEWALT Grinding Wheel, Double Row, Diamond Cup, 4-1/2-Inch (DW4774) - Image 2](https://m.media-amazon.com/images/I/711b2XWyi5L.jpg) ## Questions & Answers **Q: Can this be attached to a standard drill?** A: This has a threaded 5/8" arbor for a hand grinder. 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 ### ⭐⭐⭐⭐⭐ Does the job *by R***G on 14 April 2026* I got this to remove thin set in a small area where i was changing tile.

Getting lots of use out of it. But you need to buy the dust shroud attachment or spent days cleaning afterwards. With the dust shroud I used it inside my house in the basement even. DeWalt shroud doesn't fit vacuum hose, but I bought a rubber plumbing (fernco) fitting with hose clamps to connect it to the vacuum hose. perfect. Doesn't do a really smooth job on concrete, but I might buy a finer one to clean it up a bit after. Cleaned up my shop floor and more. Looks great now. about 2hrs of grinding. bit tough on the knees. ## 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? - 🛒 **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.ie/products/335941356-dewalt-grinding-wheel-double-row-diamond-cup-4-1-2](https://www.desertcart.ie/products/335941356-dewalt-grinding-wheel-double-row-diamond-cup-4-1-2) --- *Product available on Desertcart Ireland* *Store origin: IE* *Last updated: 2026-08-11*
