Built on a 1\/8 inch shank, this ball-shaped carbide bur features a double cut tooth style and an AlTiN coating that extends tool life under high-heat cutting conditions. The 5\/64 inch (0.0781 inch) cutting diameter and 0.0670 inch length of cut make it suited for tight radii, contoured surfaces, and detail work where a larger bur cannot reach. Installation and use are handled by machinists, tool-and-die makers, and fabrication professionals.\u003c\/p\u003e\n\u003cp\u003eThis bur is used in applications involving cast iron, steel, and stainless steel. The ball head geometry and 270-degree included angle allow it to work inside cavities, blend weld seams, deburr drilled holes, and profile curved surfaces. It is a compact single-piece rotary tool consumable appropriate for use in die grinders and rotary tool spindles accepting a 1\/8 inch shank. Overall length of 1.5 inches keeps tool runout minimal in handheld and bench-mounted setups alike.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSphere (ball) head geometry with a 270-degree included angle for contouring and cavity work\u003c\/li\u003e\n  \u003cli\u003eDouble cut tooth style for faster material removal and smoother finish compared to single cut\u003c\/li\u003e\n  \u003cli\u003eAlTiN coating improves heat resistance and extends service life on ferrous materials\u003c\/li\u003e\n  \u003cli\u003eSolid carbide head construction for hardness and wear resistance\u003c\/li\u003e\n  \u003cli\u003e1\/8 inch shank diameter fits standard die grinders and rotary tools\u003c\/li\u003e\n  \u003cli\u003eCompact 5\/64 inch cutting diameter suited for tight radii and detailed deburring\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in die grinders and rotary tools with a 1\/8 inch collet.

Always wear eye protection and appropriate PPE when operating rotary burs on ferrous materials. Inspect the bur for chipping or wear before each use and do not operate at speeds exceeding the tool rating for the shank diameter. Allow the bur to cool between extended cutting passes on stainless steel to reduce heat buildup.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHead Shape\u003c\/strong\u003e: Sphere (Ball)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Diameter\u003c\/strong\u003e: 0.0781 inches (5\/64 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 0.0670 inches (1.70 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 1.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 1\/8 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTooth Style\u003c\/strong\u003e: Double Cut\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eIncluded Angle\u003c\/strong\u003e: 270 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHead Material\u003c\/strong\u003e: Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHead Coating\u003c\/strong\u003e: AlTiN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Application\u003c\/strong\u003e: Cast Iron, Steel, Stainless Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eIndustry Specification\u003c\/strong\u003e: SD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 27112809\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.01 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: HARVEY TOOL\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 980578-C3\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HARVEY TOOL","offers":[{"title":"Default Title","offer_id":51731113967922,"sku":"980578-C3","price":102.73,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/703fb2022397850a0750b3899e7fc96e_cb2a6a6f-5d88-4961-85ac-72cc652d4406.jpg?v=1788727120","url":"https:\/\/voomisupply.com\/products\/harvey-tool-980578-c3-abrasive-bur-sphere-5-64-in-double-cut","provider":"Voomi Supply","version":"1.0","type":"link"}
