Built from high speed steel with a chrome finish, it delivers the hardness and wear resistance needed for production tapping in ferrous and non-ferrous materials. This tap cuts a 1 inch 11-1\/2 NPT thread profile, the standard taper used in pressure-rated pipe and fitting connections across plumbing, HVAC, and industrial piping systems. The 5-flute design provides a regular hook angle for consistent chip evacuation in through-hole and blind applications. Machinists, pipefitters, and maintenance technicians use this tap when threading ports, fittings, or manifold bodies to accept standard NPT male pipe threads.\u003c\/p\u003e\n\u003cp\u003eThis tap is suited for threading operations on pipe flanges, manifolds, valve bodies, and mechanical assemblies that require a leak-resistant tapered thread connection. The 1 inch 11-1\/2 NPT size is widely specified in commercial plumbing, hydronic heating, refrigeration piping, and industrial fluid handling systems. It is appropriate for both manual tapping with a tap wrench and machine tapping in a drill press or CNC setup with proper feed control and cutting fluid.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e1 inch 11-1\/2 NPT thread profile for standard tapered pipe thread applications\u003c\/li\u003e\n  \u003cli\u003eHigh speed steel construction for durability in ferrous and non-ferrous materials\u003c\/li\u003e\n  \u003cli\u003eChrome finish resists corrosion and reduces friction during cutting\u003c\/li\u003e\n  \u003cli\u003e5-flute design with regular hook angle supports stable chip flow\u003c\/li\u003e\n  \u003cli\u003e1.75 inch thread length accommodates full NPT taper engagement\u003c\/li\u003e\n  \u003cli\u003eShank diameter of 1.125 inches and square drive size of 0.843 inches for secure tap wrench or machine chuck fitment\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style pipe tap for use in standard NPT pipe threading operations on compatible workpieces requiring a 1 inch 11-1\/2 tapered pipe thread form.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eThis tap is installed and used by machinists, pipefitters, or maintenance technicians performing threading operations. Always apply an appropriate cutting fluid for the workpiece material to extend tool life and improve thread finish. Secure the workpiece firmly before tapping and align the tap perpendicular to the hole to prevent thread damage or tap breakage. When machine tapping, use a tapping head or controlled feed to maintain proper axial alignment throughout the cut.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: NPT\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1 - 11-1\/2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 1.75 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 5\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHook\u003c\/strong\u003e: Regular\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 1.125 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSquare Size\u003c\/strong\u003e: 0.843 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: High Speed Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Chrome\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.2 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: HERTEL\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: R127784K-S\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51746672345394,"sku":"R127784K-S","price":256.72,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/409f41cb2ea8d0006a75261dbda1c439.jpg?v=1788872433","url":"https:\/\/voomisupply.com\/products\/hertel-r127784k-s-pipe-tap-1-11-1-2-npt-5-flute-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
