It is designed for hand threading work across a variety of materials and produces a Class 2B thread fit. The straight flutes are ground to promote rapid chip removal, keeping the threading process efficient and reducing clogging during use. This tap is well suited for routine maintenance and repair work, particularly for rethreading applications where ultra-high accuracy or tight tolerance threads are not required. A 21\/32 inch drill bit is the recommended tap drill size for this thread specification.\u003c\/p\u003e\n\u003cp\u003eThis tap is used in general mechanical maintenance, repair, and fabrication scenarios where 3\/4 inch x 10 NC threads need to be cut or restored by hand. Typical applications include rethreading damaged fastener holes in metal fixtures, structural components, and equipment frames. It is appropriate for use in both shop and field environments by machinists, millwrights, pipefitters, and general maintenance tradespeople working with standard fractional fastener sizes.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e3\/4 inch x 10 National Coarse (NC) thread specification for standard fractional fastener compatibility\u003c\/li\u003e\n  \u003cli\u003eCarbon steel construction provides adequate hardness for hand tapping common metals and materials\u003c\/li\u003e\n  \u003cli\u003eStraight flutes ground for rapid chip removal and efficient threading performance\u003c\/li\u003e\n  \u003cli\u003eProduces a Class 2B thread fit, suitable for general-purpose maintenance and repair applications\u003c\/li\u003e\n  \u003cli\u003eRecommended tap drill size: 21\/32 inch\u003c\/li\u003e\n  \u003cli\u003eDesigned specifically for hand threading work, not CNC or power tapping\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a general-purpose fractional hand tap for use wherever a 3\/4 inch x 10 NC thread must be cut or restored by hand in a variety of common materials.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eThis tap is intended for hand threading only — do not use in power tapping equipment or drill presses at speed, as this may damage the tap or workpiece. Before tapping, drill the pilot hole to 21\/32 inch using a properly secured workpiece. Apply cutting fluid appropriate for the material being tapped to reduce friction and extend tap life. Inspect the tap for damage before each use and replace if flutes show signs of wear or chipping.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 3\/4 inch x 10\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Type\u003c\/strong\u003e: National Coarse (NC)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Class\u003c\/strong\u003e: 2B\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTap Type\u003c\/strong\u003e: Fractional Hand Tap\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Style\u003c\/strong\u003e: Straight\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Carbon Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRecommended Drill Bit Size\u003c\/strong\u003e: 21\/32 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 6\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1.75 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: CENTURY DRILL TOOL CO INC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 97117\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CENTURY DRILL \u0026 TOOL","offers":[{"title":"Default Title","offer_id":51558179897650,"sku":"97117","price":89.06,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/481257d7992c5435e07c90f312bb4416_c7ecc2cf-3cb4-4e63-aaf4-a1897195ed9a.jpg?v=1786405483","url":"https:\/\/voomisupply.com\/products\/century-drill-tool-co-inc-97117-3-4x10-nc-fractional-tap","provider":"Voomi Supply","version":"1.0","type":"link"}
