Shaped as a ball (point shape code B124), it runs at up to 91,770 RPM and delivers a fine, 90-grit cut on ferrous and non-ferrous metals, hardened steel, and cast iron. The hard vitrified bond holds the abrasive grain firmly during high-speed rotary tool use, making it a dependable choice for die grinders, rotary tools, and bench grinders with the appropriate collet. Licensed tradespeople and machining professionals reach for this style of mounted point when internal radii, ports, or irregular surfaces require controlled stock removal.\u003c\/p\u003e\n\u003cp\u003eThis mounted point is suited for tool-and-die work, mold finishing, weld cleanup, and general precision grinding tasks in both shop and field environments. Its compact ball geometry allows access to bores, cavities, and curved profiles that flat or cylindrical wheels cannot reach. The 1\/8-inch shank is a standard size compatible with most die grinder and rotary tool collets used in metalworking and maintenance trades.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eBall profile (B124) accesses curved surfaces, bores, and contoured cavities\u003c\/li\u003e\n  \u003cli\u003e90-grit fine grade removes material while leaving a relatively smooth finish\u003c\/li\u003e\n  \u003cli\u003eAluminum oxide abrasive for use on steel, cast iron, and general ferrous metals\u003c\/li\u003e\n  \u003cli\u003eVitrified bond provides hard, rigid grain retention at high RPM\u003c\/li\u003e\n  \u003cli\u003eRated to 91,770 RPM for use with standard die grinders and rotary tools\u003c\/li\u003e\n  \u003cli\u003e1\/8-inch shank diameter fits widely available collets without adapters\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with die grinders and rotary tools accepting a 1\/8-inch collet.

Always confirm the tool spindle speed does not exceed the 91,770 RPM rating before operation. Inspect the mounted point for cracks or chips before each use and discard any damaged piece. Wear appropriate PPE including eye protection and ensure the work area is clear of personnel before engaging the tool.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePoint Shape\u003c\/strong\u003e: Ball\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePoint Shape Code\u003c\/strong\u003e: B124\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\u003eColor\u003c\/strong\u003e: Brown\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHead Thickness\u003c\/strong\u003e: 0.125 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\u003eOverall Length\u003c\/strong\u003e: 1.625 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum RPM\u003c\/strong\u003e: 91,770\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.0067 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23131514\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: 61463624474\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NORTON","offers":[{"title":"Default Title","offer_id":51538843107634,"sku":"61463624474","price":23.32,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/a1170643adbece423c07528e78db6004.jpg?v=1785828122","url":"https:\/\/voomisupply.com\/products\/norton-61463624474-mounted-point-b124-90-grit-fine","provider":"Voomi Supply","version":"1.0","type":"link"}
