Classified as shape B121, this mounted point features a fine-grade aluminum oxide abrasive bonded in a unitized construction for consistent stock removal and a uniform finish. The hard density bond holds the abrasive firmly during high-speed operation, with a maximum rated speed of 45,300 RPM. The 1\/8-inch shank fits standard die grinder collets, and the 1\/2-inch head thickness provides adequate contact area for contour work and internal cavity finishing.\u003c\/p\u003e\n\u003cp\u003eThis mounted point is suited for tool and die work, weld blending, port work, and general metalworking applications in fabrication shops, maintenance environments, and production grinding operations. The fine grade makes it appropriate for finishing passes rather than aggressive material removal. It is typically used by machinists, tool and die makers, and maintenance technicians working on ferrous metals and hard alloys where controlled surface finish is required. Sold individually per package with a minimum order quantity of 5 units.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eBall shape (B121) suited for contour grinding, deburring internal radii, and cavity blending\u003c\/li\u003e\n  \u003cli\u003eFine-grade aluminum oxide abrasive for finish-pass surface refinement\u003c\/li\u003e\n  \u003cli\u003eUnitized bond construction with hard density rating for consistent performance under load\u003c\/li\u003e\n  \u003cli\u003eMaximum operating speed of 45,300 RPM compatible with standard die grinders\u003c\/li\u003e\n  \u003cli\u003e1\/8-inch shank diameter fits common die grinder and rotary tool collets\u003c\/li\u003e\n  \u003cli\u003eCompact 1\/2-inch head thickness for access to tight contours and recessed areas\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement mounted point for die grinders and rotary tools accepting a 1\/8-inch shank collet.

Always confirm the tool's rated RPM does not exceed the 45,300 RPM maximum before mounting. Secure the shank fully into the collet and tighten per the tool manufacturer's specification before operation. Inspect the mounted point for cracks or damage before each use and do not use a damaged abrasive.\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: B121\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAbrasive Material\u003c\/strong\u003e: Aluminum Oxide\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: Unitized\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: 0.5 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\u003eMaximum RPM\u003c\/strong\u003e: 45,300 RPM\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eColor\u003c\/strong\u003e: Gray\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.25 pounds\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\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: STANDARD ABRASIVES\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 7010310349\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"3M","offers":[{"title":"Default Title","offer_id":51540535869746,"sku":"7010310349","price":53.89,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/66676798546fb844fd9cd29944b9bc91.jpg?v=1785857769","url":"https:\/\/voomisupply.com\/products\/standard-abrasives-7010310349-mounted-point-b121-fine","provider":"Voomi Supply","version":"1.0","type":"link"}
