The pointed B52 profile allows access to contoured surfaces, tight radii, and internal features where flat or wheel-style abrasives cannot reach. At 90 grit with a fine grade and hard bond density, this mounted point removes material efficiently while producing a consistent, controlled finish. It is rated to a maximum of 64,810 RPM and mounts via a 1\/8 inch diameter shank, making it compatible with standard die grinders and rotary tools used in fabrication, tool-and-die, and maintenance grinding applications.\u003c\/p\u003e\n\u003cp\u003eThis mounted point is suited for use in metalworking environments including job shops, tool rooms, and production lines where operators need a reliable abrasive for internal grinding, weld cleanup, and detailed surface work. The brown aluminum oxide grain is a general-purpose abrasive well matched to ferrous metals such as carbon steel, alloy steel, and hardened tool steel. Typical users include machinists, maintenance technicians, and fabricators working with die grinders or flexible-shaft machines.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eB52 pointed shape for access to contoured surfaces, slots, and internal profiles\u003c\/li\u003e\n  \u003cli\u003e90 grit, fine grade aluminum oxide abrasive for controlled stock removal and surface refinement\u003c\/li\u003e\n  \u003cli\u003eVitrified bond with hard density rating for consistent performance and shape retention\u003c\/li\u003e\n  \u003cli\u003e1\/8 inch shank diameter fits standard die grinder collets and rotary tool chucks\u003c\/li\u003e\n  \u003cli\u003eMaximum speed rating of 64,810 RPM for use with high-speed rotary tools\u003c\/li\u003e\n  \u003cli\u003eBrown aluminum oxide grain suited for general-purpose grinding on ferrous metals\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with die grinders, flexible-shaft machines, and rotary tools accepting a 1\/8 inch shank collet.

Always verify the tool spindle speed does not exceed the 64,810 RPM maximum rating marked for this abrasive. Wear appropriate eye protection and guarding per ANSI B7.1 and shop safety requirements. Inspect the mounted point for cracks or damage before each use and discard any abrasive that shows signs of deterioration.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePoint Shape\u003c\/strong\u003e: Pointed\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePoint Shape Code\u003c\/strong\u003e: B52\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: 90\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGrade\u003c\/strong\u003e: Fine\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBond Type\u003c\/strong\u003e: Vitrified\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDensity \/ Hardness\u003c\/strong\u003e: Hard\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHead Thickness\u003c\/strong\u003e: 0.75 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.125 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 1.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum RPM\u003c\/strong\u003e: 64,810\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eColor\u003c\/strong\u003e: Brown\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.01 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: NORTON\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 61463624422\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NORTON","offers":[{"title":"Default Title","offer_id":51541637464370,"sku":"61463624422","price":26.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/9929f04da55b38b327be05cc4f32ad69.jpg?v=1785880857","url":"https:\/\/voomisupply.com\/products\/norton-61463624422-mounted-point-b52-90-grit-fine","provider":"Voomi Supply","version":"1.0","type":"link"}
