It is designed for hand threading work across a variety of materials, producing a Class 2B thread. The straight flutes are ground to promote rapid chip removal, which keeps the threading operation clean and efficient. This tap is suited to routine maintenance and repair applications where extremely high accuracy tolerances are not the primary requirement, making it a practical shop and field tool for machinists, maintenance technicians, and general trades workers who need reliable rethreading capability.\u003c\/p\u003e\n\u003cp\u003eThis tap is intended for use in routine maintenance, repair, and rethreading tasks in residential, commercial, and light industrial settings. It excels when restoring damaged threads or cutting new NF threads in a range of common materials. The hand-tap format means it is driven manually with a tap wrench rather than a machine, giving the user direct feel and control during the threading process. A 33\/64 inch drill bit is required to prepare the correct tap drill hole before threading. The package includes 12 taps per unit.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e9\/16 inch x 18 National Fine (NF) thread specification for standard NF fastener applications\u003c\/li\u003e\n  \u003cli\u003eCarbon steel construction provides adequate hardness for threading a variety of common materials\u003c\/li\u003e\n  \u003cli\u003eStraight flutes ground for rapid chip removal during hand threading\u003c\/li\u003e\n  \u003cli\u003eProduces a Class 2B thread fit suitable for general-purpose maintenance and repair\u003c\/li\u003e\n  \u003cli\u003eDesigned for hand threading with a tap wrench — no machine required\u003c\/li\u003e\n  \u003cli\u003ePackaged 12 per unit for shop stock or multi-tech supply\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a general-purpose fractional hand tap for cutting or restoring 9\/16 inch x 18 National Fine threads.

Before threading, drill the tap hole to 33\/64 inches to achieve the correct minor diameter for a Class 2B fit. Apply cutting fluid or tapping oil appropriate to the workpiece material to reduce friction and extend tap life. Back the tap out periodically during threading to break and clear chips, and avoid forcing the tap, which can cause breakage.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 9\/16 inches x 18\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: National Fine (NF)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Class\u003c\/strong\u003e: 2B\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 Tap Drill\u003c\/strong\u003e: 33\/64 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 12 per package\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1.68 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: 95114\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CENTURY DRILL \u0026 TOOL","offers":[{"title":"Default Title","offer_id":51557832261938,"sku":"95114","price":112.37,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/481257d7992c5435e07c90f312bb4416.jpg?v=1786396352","url":"https:\/\/voomisupply.com\/products\/century-drill-tool-95114-fractional-tap-9-16-x-18-nf","provider":"Voomi Supply","version":"1.0","type":"link"}
