The wheel measures 7 inches in diameter and 1.5 inches thick, with a 5\/8-inch arbor hole for secure mounting on compatible angle grinders and surface grinders. Rated to 8700 RPM, the medium-grit diamond abrasive delivers consistent stock removal while maintaining dimensional control. It weighs 2.4 pounds and is sold individually. Licensed tradespeople working concrete floors, cured coatings, or similar hard substrates will find this wheel suited to production-level surface prep.\u003c\/p\u003e\n\u003cp\u003eThe DW4775 is intended for use in surface grinding applications where a diamond abrasive is required. Typical use cases include prep work on concrete slabs prior to coating or overlay installation, removal of surface contaminants or high spots, and general masonry grinding. It is appropriate for both residential and light commercial project environments. The medium grit designation makes it a practical choice when a balance between cut rate and surface finish is needed, rather than an aggressive coarse cut or a finishing-grade fine grit.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eDiamond abrasive blade material for cutting hard substrates such as concrete and masonry\u003c\/li\u003e\n  \u003cli\u003e7-inch diameter provides broad contact area for efficient surface coverage\u003c\/li\u003e\n  \u003cli\u003e1.5-inch wheel thickness supports stable, even grinding passes\u003c\/li\u003e\n  \u003cli\u003e5\/8-inch arbor hole fits standard angle grinder and surface grinder spindles\u003c\/li\u003e\n  \u003cli\u003e8700 RPM maximum speed rating for compatibility with common grinder platforms\u003c\/li\u003e\n  \u003cli\u003eMedium grit grade balances material removal rate with surface finish quality\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or direct-use diamond grinding wheel for 7-inch surface grinders and angle grinders equipped with a 5\/8-inch arbor spindle.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified tradesperson familiar with abrasive wheel safety. Before mounting, disconnect power and verify the grinder spindle arbor matches the 5\/8-inch arbor hole. Inspect the wheel for cracks or chips before each use and never operate above the rated 8700 RPM. Always follow ANSI B7.1 abrasive wheel safety standards and use appropriate personal protective equipment including eye, face, and hearing protection.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBlade Diameter\u003c\/strong\u003e: 7 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBlade Thickness\u003c\/strong\u003e: 1.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eArbor Hole Diameter\u003c\/strong\u003e: 0.625 inches (5\/8 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum RPM\u003c\/strong\u003e: 8700 RPM\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGrit Grade\u003c\/strong\u003e: Medium\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBlade Material\u003c\/strong\u003e: Diamond\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 2.4 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 27112800\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: DEWALT\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: DW4775\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"DEWALT","offers":[{"title":"Default Title","offer_id":51563803377970,"sku":"DW4775","price":150.59,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/9065212cd3352e6f5cb89908802ecf2a.jpg?v=1786503817","url":"https:\/\/voomisupply.com\/products\/dewalt-dw4775-diamond-surface-grinding-wheel-7-in-medium-grit","provider":"Voomi Supply","version":"1.0","type":"link"}
