This flat cone profile (shape code B91) measures 5\/8 inches thick and mounts on a 1\/8 inch diameter shank with a 1-1\/2 inch shank length. Rated to 61,110 RPM, it delivers consistent material removal at a 60 grit, medium grade cut. It is typically used with die grinders and rotary tools by machinists, tool and die makers, and maintenance technicians working on internal bores, contoured surfaces, and hard-to-reach areas.\u003c\/p\u003e\u003cp\u003eThis mounted point is suited for bench and portable grinding applications in manufacturing, fabrication, and maintenance environments. The flat cone shape makes it effective for work on concave surfaces, chamfers, and angled profiles. The vitrified bond provides a rigid, free-cutting action that holds grit securely under load, making it a practical choice for production grinding or detail finishing work on steel, iron, and similar hard metals. It ships in a minimum order quantity of 5 units.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eFlat cone profile (B91) for grinding concave and angled surfaces\u003c\/li\u003e\n\u003cli\u003e60 grit aluminum oxide abrasive with medium grade for balanced stock removal and surface finish\u003c\/li\u003e\n\u003cli\u003eVitrified bond for rigid, free-cutting action and consistent performance\u003c\/li\u003e\n\u003cli\u003e1\/8 inch shank diameter compatible with standard die grinder collets\u003c\/li\u003e\n\u003cli\u003eMaximum rated speed of 61,110 RPM for high-speed rotary tool use\u003c\/li\u003e\n\u003cli\u003e5\/8 inch head thickness with 1-1\/2 inch shank length for reach into confined areas\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or standard-supply mounted point for die grinders and rotary tools accepting a 1\/8 inch collet or chuck.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eMounted points must be installed and used by personnel familiar with abrasive tool safety practices per ANSI B7.1 guidelines. Verify the tool spindle speed does not exceed the 61,110 RPM maximum rating marked on the product before mounting. Inspect the point for cracks or chips before each use and discard any damaged abrasive. Secure the shank fully into the collet to the recommended depth and ensure the collet nut is tightened before operating.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003ePoint Shape\u003c\/strong\u003e: Flat Cone\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePoint Shape Code\u003c\/strong\u003e: B91\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: 60\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGrade\u003c\/strong\u003e: Medium\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBond Type\u003c\/strong\u003e: Vitrified\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHead Thickness\u003c\/strong\u003e: 5\/8 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 1\/8 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 1-1\/2 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum RPM\u003c\/strong\u003e: 61,110\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23131514\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMinimum Order Quantity\u003c\/strong\u003e: 5\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: 61463624443\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NORTON","offers":[{"title":"Default Title","offer_id":51541281177906,"sku":"61463624443","price":27.29,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/9603862642ddc5a647a64cd20803ccf4.jpg?v=1785871319","url":"https:\/\/voomisupply.com\/products\/norton-61463624443-mounted-point-b91-60-grit-aluminum-oxide","provider":"Voomi Supply","version":"1.0","type":"link"}
