The extractor handles bolt and screw sizes from 1-1\/8 inches to 1-3\/8 inches and can also remove 3\/4-inch pipe. The required pilot drill bit size is 13\/16 inches, and the manufacturer recommends using left-hand cobalt drill bits for best results. This tool is sold as a package of 2 units and weighs 1.74 pounds. It is used by mechanics, machinists, plumbers, and general trade professionals who encounter seized or snapped fasteners during service and repair work.\u003c\/p\u003e\n\u003cp\u003eThis extractor is suited for industrial, commercial, and residential applications where fasteners have broken off inside threaded holes, pipe fittings, or structural connections. Typical scenarios include engine repair, pipe fitting removal, and structural disassembly where conventional removal methods are not viable. The spiral flute design bites aggressively into the broken fastener as reverse torque is applied, making it effective on corroded or heavily damaged hardware.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eRemoves broken bolts and screws sized 1-1\/8 inches to 1-3\/8 inches\u003c\/li\u003e\n  \u003cli\u003eRemoves broken 3\/4-inch pipe\u003c\/li\u003e\n  \u003cli\u003eSpiral flute geometry applies aggressive grip under reverse torque\u003c\/li\u003e\n  \u003cli\u003eRequires 13\/16-inch pilot drill bit; compatible with left-hand cobalt drill bits\u003c\/li\u003e\n  \u003cli\u003eSold as a 2-piece package\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement-grade extractor for use with any standard drill press, hand drill, or tap wrench capable of accepting the appropriate drive shank, when removing broken fasteners in the 1-1\/8-inch to 1-3\/8-inch bolt and screw range or 3\/4-inch pipe applications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eA licensed mechanic, machinist, or plumber typically performs broken fastener extraction as part of service or repair work. Before beginning, ensure the workpiece is secured and all system pressure or power is relieved. Drill the pilot hole to the recommended 13\/16-inch diameter using a left-hand cobalt drill bit, then insert the extractor and apply steady counterclockwise torque. Do not apply excessive side load or hammer the extractor, as this can cause fracture inside the bore.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eExtractor Size\u003c\/strong\u003e: No. 8\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBolt and Screw Removal Range\u003c\/strong\u003e: 1-1\/8 inches to 1-3\/8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePipe Removal Size\u003c\/strong\u003e: 3\/4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRequired Pilot Drill Bit Size\u003c\/strong\u003e: 13\/16 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1.74 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUnit of Measure\u003c\/strong\u003e: EA\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: CENTURY DRILL TOOL CO INC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 73308\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CENTURY DRILL \u0026 TOOL","offers":[{"title":"Default Title","offer_id":51558247694642,"sku":"73308","price":50.72,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/0011378906e4ef27372e9aa8ffa6c7f1.jpg?v=1786407280","url":"https:\/\/voomisupply.com\/products\/century-drill-73308-no-8-spiral-flute-screw-extractor","provider":"Voomi Supply","version":"1.0","type":"link"}
