The square flute design bites into damaged fasteners as it turns, gripping without spreading the surrounding material. This makes it well suited for thin-wall extractions where a tapered extractor would crack or deform the workpiece. It handles bolt and screw sizes from 1\/2 inch to 9\/16 inch, and removes 1\/4-inch pipe. A 5\/16-inch left-hand cobalt drill bit is the recommended pilot drill for this extractor size.\u003c\/p\u003e\n\u003cp\u003eThis extractor is used across plumbing, HVAC, electrical, and general mechanical service work wherever a fastener has sheared off during removal or installation. It is a standard tool for service technicians and maintenance trades working on equipment panels, pipe fittings, flanges, and structural connections. The left-hand drill bit approach often backs out the broken fastener during the drilling step before the extractor is even needed, saving time on the job.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSquare flute design grips broken fasteners without spreading thin walls\u003c\/li\u003e\n  \u003cli\u003eRemoves bolt and screw sizes from 1\/2 inch to 9\/16 inch\u003c\/li\u003e\n  \u003cli\u003eRemoves 1\/4-inch broken pipe sections\u003c\/li\u003e\n  \u003cli\u003eRequires 5\/16-inch pilot hole — left-hand cobalt drill bit recommended\u003c\/li\u003e\n  \u003cli\u003eIdeal for thin-wall extraction applications where tapered extractors are not suitable\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with broken bolts and screws in the 1\/2-inch to 9\/16-inch range and broken 1\/4-inch pipe, using a 5\/16-inch left-hand cobalt drill bit for pilot hole preparation.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eDe-energize and lock out any equipment before attempting fastener extraction. Drill the pilot hole to the correct depth using a 5\/16-inch left-hand cobalt drill bit before engaging the extractor. Apply steady, even pressure when turning the extractor counterclockwise — do not force or impact the extractor, as broken extractors are extremely difficult to remove. Follow applicable safety and trade guidelines for the specific system being serviced.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eExtractor Number\u003c\/strong\u003e: 4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Square\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBolt\/Screw Size Range\u003c\/strong\u003e: 1\/2 inch to 9\/16 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePipe Size\u003c\/strong\u003e: 1\/4 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRecommended Pilot Drill Size\u003c\/strong\u003e: 5\/16 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRecommended Drill Type\u003c\/strong\u003e: Left-hand cobalt\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.32 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: 73204\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CENTURY DRILL \u0026 TOOL","offers":[{"title":"Default Title","offer_id":51559404405042,"sku":"73204","price":23.43,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/bd5bb0fafed93e0879aaf218c3b30269.jpg?v=1786431416","url":"https:\/\/voomisupply.com\/products\/century-drill-tool-73204-no-4-square-flute-screw-extractor","provider":"Voomi Supply","version":"1.0","type":"link"}
