It uses a zirconia alumina abrasive grain bonded with a resinoid bond, making it well-suited for high-pressure grinding where heat and wear resistance matter. The point measures 1.5 inches thick, mounts on a 0.25-inch diameter shank with a 1.5-inch shank length, and is rated to a maximum of 24,490 RPM. At 24 grit, this is a very coarse cutting tool intended for rapid material removal rather than finishing work. Fabricators, welders, and tool-and-die workers are the typical end users.\u003c\/p\u003e\n\u003cp\u003eThis mounted point is used in die grinders and rotary tools for grinding internal bores, contoured surfaces, ports, and recesses where flat or cup wheels cannot reach. The W221 cylinder shape provides a broad flat face and side grinding capability in a single tool. Common applications include weld cleanup on pipe and structural steel, deburring cast iron and steel components, and surface prep on hard alloys. The very coarse 24-grit cut rate makes it a roughing tool; follow with finer grits if a smoother finish is required.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eZirconia alumina grain for durable, high-stock-removal grinding on ferrous metals and hard alloys\u003c\/li\u003e\n  \u003cli\u003e24 grit very coarse grade for fast, aggressive material removal in roughing operations\u003c\/li\u003e\n  \u003cli\u003eResinoid bond provides flexibility and resistance to heat generated during high-pressure grinding\u003c\/li\u003e\n  \u003cli\u003eW221 cylinder shape offers both face and side grinding capability in confined areas\u003c\/li\u003e\n  \u003cli\u003e0.25-inch shank diameter fits standard die grinder and rotary tool collets\u003c\/li\u003e\n  \u003cli\u003e24,490 RPM maximum speed rating supports use in typical pneumatic and electric die grinders\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 0.25-inch shank.

Before mounting, confirm the tool is disconnected from its air supply or power source and the collet is clean and undamaged. Insert the shank fully into the collet and tighten securely before operating. Always verify the grinder RPM rating does not exceed the 24,490 RPM maximum marked on this abrasive, and use appropriate eye protection and guarding per ANSI B7.1 standards.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePoint Shape\u003c\/strong\u003e: Cylinder\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePoint Shape Code\u003c\/strong\u003e: W221\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAbrasive Material\u003c\/strong\u003e: Zirconia Alumina\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGrit\u003c\/strong\u003e: 24\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGrade\u003c\/strong\u003e: Very Coarse\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBond Type\u003c\/strong\u003e: Resinoid\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHead Thickness\u003c\/strong\u003e: 1.5 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\u003eMaximum RPM\u003c\/strong\u003e: 24,490\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.1 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: 61463616473\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NORTON","offers":[{"title":"Default Title","offer_id":51542915186994,"sku":"61463616473","price":58.16,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/ec6b021d3b62d055e533f41e5025c3e1.jpg?v=1785910818","url":"https:\/\/voomisupply.com\/products\/norton-61463616473-mounted-point-w221-24-grit-zirconia","provider":"Voomi Supply","version":"1.0","type":"link"}
