It uses a zirconia alumina abrasive material at 20 grit, placing it firmly in the very coarse grade range for fast cutting action. The 5\/8-11 threaded arbor hole mounts directly to standard angle grinders and die grinders used by welders, fabricators, and maintenance technicians. With a maximum operating speed of 18,145 RPM, it is built for high-speed grinding applications where material removal rate matters most.\u003c\/p\u003e\n\u003cp\u003eThis round tip cone is suited for weld blending, deburring, and surface preparation on structural steel, fabricated components, and cast metal parts. The cone shape allows access to contoured surfaces, inside corners, and irregular profiles that flat wheels cannot reach efficiently. It is a common choice in metal fabrication shops, industrial maintenance environments, and any application requiring rapid material removal in confined or curved geometries.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eType 17R round tip cone geometry for access to contoured and recessed surfaces\u003c\/li\u003e\n  \u003cli\u003eZirconia alumina abrasive material for fast, aggressive cutting on metal\u003c\/li\u003e\n  \u003cli\u003e20 grit, very coarse grade for maximum stock removal rate\u003c\/li\u003e\n  \u003cli\u003e5\/8-11 threaded arbor hole fits standard angle and die grinder spindles\u003c\/li\u003e\n  \u003cli\u003e18,145 RPM maximum operating speed for high-speed tool compatibility\u003c\/li\u003e\n  \u003cli\u003eMinimum diameter of 3\/4 inch for use in tight or contoured work areas\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use on angle grinders and die grinders with a 5\/8-11 threaded spindle.

Always confirm the tool spindle speed does not exceed the 18,145 RPM maximum rated speed of the wheel before mounting. Power down and disconnect the grinder before mounting or removing the cone. Inspect the abrasive for cracks or damage before each use and follow ANSI B7.1 safety requirements for the use, care, and protection of abrasive wheels.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShape\u003c\/strong\u003e: Round Tip Cone\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWheel Type Number Code\u003c\/strong\u003e: 17R\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAbrasive Material\u003c\/strong\u003e: Zirconia Alumina\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGrade\u003c\/strong\u003e: Very Coarse\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGrit\u003c\/strong\u003e: 20\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eArbor Hole Thread Size\u003c\/strong\u003e: 5\/8-11\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Diameter\u003c\/strong\u003e: 0.75 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum RPM\u003c\/strong\u003e: 18,145\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.57 pounds\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: 66253344384\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NORTON","offers":[{"title":"Default Title","offer_id":51542324871474,"sku":"66253344384","price":50.91,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/85a8c3b05e3ffade17232f7d32b68a72.jpg?v=1785898189","url":"https:\/\/voomisupply.com\/products\/norton-66253344384-round-tip-cone-20-grit-5-8-11-arbor","provider":"Voomi Supply","version":"1.0","type":"link"}
