It features an aluminum oxide abrasive bonded with a resinoid bond at 80 grit coarse grade, making it well-suited for aggressive stock removal on ferrous metals and hard alloys. The point measures 0.5 inches thick with an overall length of 2 inches, including a 1.5-inch shank. With a rated maximum speed of 45,370 RPM, it is built for use on die grinders and rotary tools operated by machinists, tool-and-die workers, and maintenance technicians.\u003c\/p\u003e\u003cp\u003eThis mounted point is used in industrial maintenance, fabrication, and toolroom applications where a standard flat wheel cannot reach. The B121 ball shape is appropriate for grinding internal radii, weld blending inside bores, and smoothing cast or machined surfaces. It fits standard 0.25-inch collet die grinders and pneumatic or electric rotary tools. It is packaged individually with a minimum order quantity of 5 units, making it suitable for shop stock replenishment.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eB121 ball point shape for grinding internal curves, bores, and contoured surfaces\u003c\/li\u003e\n\u003cli\u003e80 grit coarse aluminum oxide abrasive for fast, aggressive stock removal\u003c\/li\u003e\n\u003cli\u003eResinoid bond with medium density for consistent cut rate and wheel integrity\u003c\/li\u003e\n\u003cli\u003eRated to 45,370 RPM for compatibility with standard die grinder operating speeds\u003c\/li\u003e\n\u003cli\u003e0.25-inch shank diameter fits common collet sizes on die grinders and rotary tools\u003c\/li\u003e\n\u003cli\u003ePink aluminum oxide formulation suited for ferrous metals and hardened steels\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with die grinders and rotary tools accepting a 0.25-inch shank collet.

Before mounting, verify the tool spindle speed does not exceed the rated maximum of 45,370 RPM. Always power down and disconnect the tool before changing mounted points. Wear appropriate eye protection and follow ANSI B7.1 safety standards for abrasive wheel use.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\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\u003eGrit\u003c\/strong\u003e: 80\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGrade\u003c\/strong\u003e: Coarse\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBond Type\u003c\/strong\u003e: Resinoid\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDensity\/Hardness\u003c\/strong\u003e: Medium\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eColor\u003c\/strong\u003e: Pink\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum RPM\u003c\/strong\u003e: 45,370\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: 0.25 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: 2 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.03 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\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23131514\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: MERIT ABRASIVES\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 69078645338\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"MERIT","offers":[{"title":"Default Title","offer_id":51558966821170,"sku":"69078645338","price":28.17,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/4a0ff6bfdaa5a9efe691f889cff26c03.jpg?v=1786424320","url":"https:\/\/voomisupply.com\/products\/merit-abrasives-69078645338-mounted-point-b121-80-grit","provider":"Voomi Supply","version":"1.0","type":"link"}
