It measures 7\/8 inch in diameter and 3\/16 inch thick, with a 1\/16 inch arbor hole. The wheel is constructed from silicon carbide abrasive bonded in a rubber matrix at a medium grade, allowing it to cut aggressively enough to remove material while maintaining enough compliance to avoid damaging delicate surfaces. It is rated to 25000 RPM. Machinists, tool and die makers, jewelers, and precision instrument technicians are the primary installers and users of this type of wheel.\u003c\/p\u003e\n\u003cp\u003eThis wheel is suited for precision grinding and deburring applications where surface finish and dimensional control matter more than stock removal rate. Typical applications include grinding on aerospace components, electronic parts, jewelry, instruments, dies, molds, light castings, plastic articles, and super sensitive scientific devices. Its small diameter and rubber bond make it a strong choice for confined areas and workpieces that cannot tolerate the aggressive action of vitrified or resinoid wheels. It is sold individually with a minimum order quantity of 100 units.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSilicon carbide abrasive for effective cutting on non-ferrous metals, plastics, and hard non-metallic materials\u003c\/li\u003e\n  \u003cli\u003eRubber bond provides a degree of flexibility and surface compliance not found in vitrified wheels\u003c\/li\u003e\n  \u003cli\u003eMedium grade abrasive balances cut rate with surface finish quality\u003c\/li\u003e\n  \u003cli\u003e25000 RPM maximum speed rating supports use on high-speed rotary tools and spindles\u003c\/li\u003e\n  \u003cli\u003eNo-recess design for straightforward mounting on compatible arbors\u003c\/li\u003e\n  \u003cli\u003eSmall form factor at 7\/8 inch diameter suits tight clearances and intricate workpiece geometry\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with aerospace components, control mechanisms, dies, electronic parts, instruments, jewelry, light castings, molds, plastic articles, and super sensitive scientific devices where fine surface grinding is required.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eThis wheel is installed by machinists and precision tooling technicians on rotary tools, die grinders, or spindle machines. Before mounting, verify that the machine spindle speed does not exceed the 25000 RPM rating marked on the wheel. Inspect the wheel for chips or cracks prior to mounting and never use a damaged wheel. Follow ANSI B7.1 safe use guidelines for abrasive wheels, including proper guard installation and secure arbor nut torque per the machine manufacturer specification.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDiameter\u003c\/strong\u003e: 7\/8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 3\/16 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHole Size\u003c\/strong\u003e: 1\/16 inches\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: Rubber\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGrade\u003c\/strong\u003e: Medium\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum RPM\u003c\/strong\u003e: 25000 RPM\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRecess Type\u003c\/strong\u003e: No Recess\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWheel Color\u003c\/strong\u003e: Brown\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Weight\u003c\/strong\u003e: 1.25 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\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: CRATEX\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 76 M\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CRATEX","offers":[{"title":"Default Title","offer_id":67906258338098,"sku":"76 M","price":20477.89,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/439c1826bef800895776b74e1bc23911.jpg?v=1791166643","url":"https:\/\/voomisupply.com\/products\/cratex-76-m-surface-grinding-wheel-7-8-in-silicon-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
