Built from silicon carbide abrasive with a vitrified bond, this wheel delivers consistent cut rates and good form retention through the grinding pass. It measures 7 inches in diameter, 1\/4 inch thick, with a 1-1\/4 inch arbor hole, and carries an 80-grit rating with an I hardness code — a medium-grade specification well suited to moderate material removal where surface finish matters. Maximum operating speed is 3,600 RPM. At 2.86 pounds, it fits standard surface grinding machine spindles without balance issues on typical benchtop or surface grinder setups.\u003c\/p\u003e\n\u003cp\u003eThis wheel is intended for surface grinding operations on carbide tooling, ceramics, cast iron, and similar hard or brittle workpiece materials where aluminum oxide wheels are less effective. The silicon carbide grain fractures sharply and consistently, making it a practical choice for tool room applications, maintenance grinding, and production surface finishing in metalworking and fabrication environments. The vitrified bond provides rigidity and porosity control, which supports cooler cutting and accurate form holding over the wheel life. It is sized for use on standard 7-inch surface grinders common in industrial and trade shop settings.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSilicon carbide abrasive grain for effective grinding of hard, brittle, and non-ferrous materials\u003c\/li\u003e\n  \u003cli\u003eVitrified bond construction for rigid form retention and consistent cut rate\u003c\/li\u003e\n  \u003cli\u003e80 grit, I hardness (medium grade) balances material removal rate with surface finish quality\u003c\/li\u003e\n  \u003cli\u003eNon-porous, non-recessed Type 1 flat wheel profile for standard surface grinding spindle mounting\u003c\/li\u003e\n  \u003cli\u003e3,600 RPM maximum operating speed rated for safe use on compatible machines\u003c\/li\u003e\n  \u003cli\u003eGreen wheel color consistent with silicon carbide product identification convention\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use on surface grinding machines that accept a 7-inch diameter, 1\/4-inch thick Type 1 wheel with a 1-1\/4-inch arbor hole running at or below 3,600 RPM.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eGrinding wheel mounting and dressing should be performed by qualified personnel following ANSI B7.1 safety standards for the use, care, and protection of abrasive wheels. Always inspect the wheel for cracks or chips before mounting and perform a ring test. Power down and lock out the grinder before removing or installing any wheel. Never exceed the maximum RPM rating stamped on the wheel or listed in the product data.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWheel Type\u003c\/strong\u003e: Type 1 (Straight)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAbrasive Material\u003c\/strong\u003e: Silicon Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBond Type\u003c\/strong\u003e: Vitrified\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGrit\u003c\/strong\u003e: 80\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHardness Code\u003c\/strong\u003e: I\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHardness Grade\u003c\/strong\u003e: Medium\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWheel Diameter\u003c\/strong\u003e: 7 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWheel Thickness\u003c\/strong\u003e: 0.25 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eArbor Hole Size\u003c\/strong\u003e: 1.25 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum RPM\u003c\/strong\u003e: 3,600\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRecess Type\u003c\/strong\u003e: No Recess\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePorosity\u003c\/strong\u003e: Non-Porous\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWheel Color\u003c\/strong\u003e: Green\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 2.86 pounds\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: TRU-MAXX\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 66253246689\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"TRU-MAXX","offers":[{"title":"Default Title","offer_id":51739260354866,"sku":"66253246689","price":33.05,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/ac82f207b41c57b2c22da7264e76bd5f.jpg?v=1788812316","url":"https:\/\/voomisupply.com\/products\/tru-maxx-66253246689-surface-grinding-wheel-80-grit-7-in","provider":"Voomi Supply","version":"1.0","type":"link"}
