It measures 7\/8 inches in diameter, 1\/8 inches thick, and accepts a 1\/16 inch arbor. The abrasive matrix combines silicon carbide grit with a rubber bond at a fine grade, producing a controlled, smooth cut that minimizes surface damage on sensitive substrates. Rated to 25,000 RPM, this wheel is suited for high-speed rotary tools and precision spindles. It ships in a package quantity of 100 units and is appropriate for machinists, toolmakers, jewelers, and electronic assembly technicians.\u003c\/p\u003e\n\u003cp\u003eThis grinding wheel is designed for fine finishing and deburring applications across a broad range of industries. Its small form factor and rubber bond construction make it particularly well-suited for work on aerospace components, dies, molds, electronic parts, instruments, jewelry, light castings, plastic articles, and super sensitive scientific devices. The silicon carbide abrasive cuts efficiently on non-ferrous metals and non-metallic materials, while the rubber bond provides cushioning that reduces the risk of workpiece damage in precision or close-tolerance finishing operations.\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 and non-metallic materials\u003c\/li\u003e\n  \u003cli\u003eRubber bond construction delivers cushioned, controlled material removal\u003c\/li\u003e\n  \u003cli\u003eFine grade abrasive minimizes surface roughness on precision workpieces\u003c\/li\u003e\n  \u003cli\u003e25,000 RPM maximum speed rating compatible with high-speed rotary and spindle tools\u003c\/li\u003e\n  \u003cli\u003eNo-recess design for straightforward mounting on standard arbors\u003c\/li\u003e\n  \u003cli\u003eCompact 7\/8 inch diameter allows access to tight geometries and small features\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eIntended for use with aerospace components, control mechanisms, dies, electronic parts, instruments, jewelry, light castings, molds, plastic articles, and super sensitive scientific devices.

Ensure the tool or spindle is fully powered down and secured before mounting or removing the wheel. Verify that the tool RPM rating meets or exceeds the 25,000 RPM maximum of this wheel before use, and inspect the wheel for cracks or chips before each session. Follow ANSI B7.1 safety requirements for the use, care, and protection of abrasive wheels.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWheel Diameter\u003c\/strong\u003e: 7\/8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWheel Thickness\u003c\/strong\u003e: 1\/8 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: Fine\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum RPM\u003c\/strong\u003e: 25,000\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWheel Color\u003c\/strong\u003e: Brown\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRecess Type\u003c\/strong\u003e: No Recess\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 100\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.89 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: CRATEX\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 74 F\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CRATEX","offers":[{"title":"Default Title","offer_id":67906030698802,"sku":"74 F","price":153.18,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/c2eaf17fc10665ecbde0a3bdb1af3f04.jpg?v=1791163259","url":"https:\/\/voomisupply.com\/products\/cratex-74-f-surface-grinding-wheel-silicon-carbide-fine","provider":"Voomi Supply","version":"1.0","type":"link"}
