The ball head geometry provides consistent cutting action on curved surfaces, cavities, and contoured workpieces. With a 1\/4-inch cutting diameter and a 1\/8-inch shank diameter, this bur mounts directly into standard rotary tool chucks and die grinders. The uncoated solid carbide construction delivers hardness and wear resistance suited to ferrous and non-ferrous metals, plastics, and composite materials. Sold individually, it meets the SD-51 industry specification for ball-type carbide burs.\u003c\/p\u003e\n\u003cp\u003eThis bur is used in toolrooms, fabrication shops, and maintenance environments where precise material removal or edge blending is required. The 1\/8-inch shank size is compatible with most handheld die grinders, rotary tools, and flexible shaft machines that accept collets or chucks of that diameter. Typical tasks include port work on castings, weld cleanup, cavity profiling, and chamfering in tight-access areas. It is appropriate for use by machinists, toolmakers, pipe fabricators, and general maintenance technicians.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eBall head shape for contouring, cavity work, and curved-surface material removal\u003c\/li\u003e\n  \u003cli\u003e1\/4-inch cutting diameter provides a compact cutting profile for tight geometry work\u003c\/li\u003e\n  \u003cli\u003e1\/8-inch shank diameter fits standard die grinder and rotary tool collets\u003c\/li\u003e\n  \u003cli\u003eSolid carbide construction for hardness, wear resistance, and long service life\u003c\/li\u003e\n  \u003cli\u003eUncoated finish — no coating delamination risk during heavy-duty cuts\u003c\/li\u003e\n  \u003cli\u003eMeets SD-51 industry specification for ball-type carbide burs\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a direct-fit replacement or supplemental tooling for rotary tools and die grinders accepting a 1\/8-inch shank collet or chuck, consistent with SD-51 specification ball burs.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by machinists or technicians using a standard die grinder or rotary tool with a compatible 1\/8-inch collet. Secure the shank fully into the collet before tightening to the tool manufacturer's specified torque. Always wear appropriate eye and face protection when operating rotary abrasive tooling. Inspect the bur for chipping or shank damage before each use and replace if any defect is observed.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eIndustry Specification\u003c\/strong\u003e: SD-51\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHead Shape\u003c\/strong\u003e: Ball\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Diameter\u003c\/strong\u003e: 0.25 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\u003eHead Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHead Coating\u003c\/strong\u003e: Uncoated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.01 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePSC Code\u003c\/strong\u003e: 5345\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 27112809\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: VALUE COLLECTION\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: -22689-1\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51701115617586,"sku":"-22689-1","price":28.92,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/16bf2392ff563b0a349d83709ae80613.jpg?v=1788398381","url":"https:\/\/voomisupply.com\/products\/value-collection-22689-1-ball-abrasive-bur-1-4-in","provider":"Voomi Supply","version":"1.0","type":"link"}
