The tap is precision cut and accurately formed to produce consistent, exact internal threads on pipe fittings and pipe ends. The tool is heat treated and tempered to achieve file-hard threads, which extends service life under repeated hand-cutting use. Licensed plumbers and pipefitters rely on this type of combo pack to drill pilot holes and cut matching NPT threads in a single coordinated operation without sourcing separate tooling.\u003c\/p\u003e\n\u003cp\u003eThis combo pack is suited for hand-cutting internal NPT threads on all types of pipe materials in residential and light commercial plumbing applications. The 1\/4-18 NPT size is a standard thread specification widely used in gas, water, and compressed-air piping systems. The included 7\/16-inch drill bit is sized to produce the correct pilot hole for the 1\/4-18 tap, eliminating guesswork when preparing pipe fittings or threaded ports in cast iron, steel, or similar materials.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e1\/4-18 NPT tap designed for internal threading on pipe fittings and pipe ends\u003c\/li\u003e\n  \u003cli\u003eIncludes matched 7\/16-inch drill bit for correct pilot hole sizing\u003c\/li\u003e\n  \u003cli\u003ePrecision-formed threads for consistent, exact thread engagement\u003c\/li\u003e\n  \u003cli\u003eHeat treated and tempered construction for file-hard threads and extended tool life\u003c\/li\u003e\n  \u003cli\u003eDesigned for hand-cutting applications\u003c\/li\u003e\n  \u003cli\u003eSold as a 2-piece combo pack\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for hand-cutting internal 1\/4-18 NPT threads on all types of pipe and pipe fittings where a standard National Pipe Thread profile is required.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by licensed plumbers or qualified pipefitters following applicable IPC and IFGC code requirements for threaded pipe connections. Always secure the workpiece in a vise and apply cutting oil to the tap before beginning thread cutting to reduce friction and improve thread quality. Use the included drill bit to establish the pilot hole before tapping. Do not force the tap; back it off periodically to clear chips and prevent breakage.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Specification\u003c\/strong\u003e: 1\/4-18 NPT\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size\u003c\/strong\u003e: 7\/16 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 2 pieces\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUnit of Measure\u003c\/strong\u003e: EA\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.24 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: 93202\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CENTURY DRILL \u0026 TOOL","offers":[{"title":"Default Title","offer_id":51557751259442,"sku":"93202","price":39.84,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/01e99b9268c9392ecd16b8942bb27575.jpg?v=1786394242","url":"https:\/\/voomisupply.com\/products\/century-drill-tool-93202-1-4-18-npt-tap-7-16-inch-drill-combo","provider":"Voomi Supply","version":"1.0","type":"link"}
