Built with an aluminum oxide abrasive bond in a resinoid matrix, this wheel delivers consistent cutting action across a range of grinding applications. It measures 4-1\/2 inches in diameter with a 7\/8-inch arbor hole and is rated to a maximum of 13,300 RPM. The 46-grit designation places it in the coarse range, suited for weld grinding, surface prep, and stock removal. Fabricators, pipefitters, and metalworkers use this wheel with standard 4-1\/2-inch angle grinders. At 0.1 pounds, it adds minimal weight to the tool during extended use.\u003c\/p\u003e\n\u003cp\u003eThis grinding wheel is intended for use on steel in fabrication shops, field welding operations, and maintenance environments where fast material removal is the priority. The Type 27 depressed center profile allows the wheel to lie nearly flat against the workpiece, making it well suited for surface grinding and weld blending. It mounts via a standard arbor connection compatible with 4-1\/2-inch right-angle grinders. The aluminum oxide abrasive and resinoid bond perform reliably on mild and carbon steel in both shop and field conditions.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eType 27 depressed center profile for flat surface and weld grinding\u003c\/li\u003e\n  \u003cli\u003eAluminum oxide abrasive with resinoid bond for durable, consistent cut rate\u003c\/li\u003e\n  \u003cli\u003e46 grit for coarse stock removal and weld grinding on steel\u003c\/li\u003e\n  \u003cli\u003e13,300 RPM maximum speed rating for 4-1\/2-inch angle grinders\u003c\/li\u003e\n  \u003cli\u003e7\/8-inch arbor hole fits standard right-angle grinder spindles\u003c\/li\u003e\n  \u003cli\u003eLightweight at 0.1 pounds for reduced operator fatigue\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement grinding wheel for use with standard 4-1\/2-inch right-angle grinders accepting a 7\/8-inch arbor.

Always power down and unplug or lock out the grinder before mounting or removing a wheel. Inspect the wheel for cracks or chips before each use and never operate above the rated maximum RPM. A proper flange and locking nut appropriate for the arbor size must be used to secure the wheel correctly.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWheel Type\u003c\/strong\u003e: Type 27 Depressed Center\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWheel Diameter\u003c\/strong\u003e: 4-1\/2 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHole Size\u003c\/strong\u003e: 7\/8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAbrasive Material\u003c\/strong\u003e: Aluminum Oxide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGrit\u003c\/strong\u003e: 46\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum RPM\u003c\/strong\u003e: 13,300\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBond Type\u003c\/strong\u003e: Resinoid\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eConnector Type\u003c\/strong\u003e: Arbor\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Application\u003c\/strong\u003e: Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.1 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23131503\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: PFERD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 64185115\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PFERD","offers":[{"title":"Default Title","offer_id":51542486942002,"sku":"64185115","price":105.23,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/b924d9f1b8ec8011dfa7a7042c4a9aa7.jpg?v=1785901661","url":"https:\/\/voomisupply.com\/products\/pferd-64185115-type-27-grinding-wheel-4-1-2-in-46-grit","provider":"Voomi Supply","version":"1.0","type":"link"}
