It measures 3 inches in diameter and 1\/4 inch thick with a 3\/8 inch arbor hole, and carries a 24-grit aluminum oxide abrasive bonded in a vitrified matrix. The T hardness code indicates a hard wheel grade suited to softer and medium-hardness workpiece materials. Rated to 20,370 RPM, it is used in flexible shaft grinders and ID grinders where controlled, high-speed stock removal is required. Machinists, tool and die technicians, and metalworking professionals typically specify this wheel for precision grinding operations.\u003c\/p\u003e\u003cp\u003eThis wheel is suited for both residential shop and light industrial environments wherever a compact 3-inch straight wheel is needed. It performs on 300 and 400 series stainless steels, hard and soft carbon steels, tool steels, titanium, super alloys, aluminum, brass, bronze, copper, cast iron, ductile iron, and gray iron. Its very coarse grade makes it appropriate for rough grinding and heavy stock removal rather than fine finishing passes. It mounts in flexible shaft grinders and ID grinders.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e24-grit aluminum oxide abrasive for very coarse, high-removal grinding\u003c\/li\u003e\n\u003cli\u003eVitrified bond provides rigidity and consistent cutting action\u003c\/li\u003e\n\u003cli\u003eT hardness code rated hard for use on softer workpiece materials\u003c\/li\u003e\n\u003cli\u003e20,370 RPM maximum speed rating for flexible shaft and ID grinder applications\u003c\/li\u003e\n\u003cli\u003eNon-porous, non-tapered, no-recess Type 1 straight wheel geometry\u003c\/li\u003e\n\u003cli\u003eSpecification grade 57A24-TBRA for traceability and consistent performance\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with flexible shaft grinders and ID grinders requiring a Type 1 straight wheel with a 3\/8 inch arbor hole.

Always power down and lock out the grinder before mounting or removing a wheel. Inspect the wheel for cracks or chips before each use and perform a ring test; do not install a damaged wheel. Verify that the grinder spindle speed does not exceed the 20,370 RPM maximum rating stamped on the wheel.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eAbrasive Material\u003c\/strong\u003e: Aluminum Oxide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWheel Type\u003c\/strong\u003e: Type 1 Straight\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBond Type\u003c\/strong\u003e: Vitrified\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWheel Diameter\u003c\/strong\u003e: 3 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\u003eHole Size\u003c\/strong\u003e: 0.375 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGrit\u003c\/strong\u003e: 24\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGrade\u003c\/strong\u003e: Very Coarse\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHardness Code\u003c\/strong\u003e: T (Hard)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum RPM\u003c\/strong\u003e: 20,370\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecification\u003c\/strong\u003e: 57A24-TBRA\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWheel Color\u003c\/strong\u003e: Black\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePorous\u003c\/strong\u003e: Non-Porous\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTapered\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRecess Type\u003c\/strong\u003e: No Recess\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.24 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23131503\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: NORTON\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 66243528831\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NORTON","offers":[{"title":"Default Title","offer_id":51542014984498,"sku":"66243528831","price":19.19,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/69f1ec975155111ff12fcc87965cda2e.jpg?v=1785889645","url":"https:\/\/voomisupply.com\/products\/norton-66243528831-surface-grinding-wheel-24-grit","provider":"Voomi Supply","version":"1.0","type":"link"}
