Built from high-speed steel (HSS) with a bright, uncoated finish, this tap handles 1-11\/2 NPS threading — a large-diameter pipe thread size used in industrial piping, fittings, and manifold applications. The 5-flute geometry provides stable cutting action and adequate chip clearance for this size range. Thread length is 1.75 inches, the shank diameter is 1.125 inches, and the square drive measures 0.843 inches for wrench engagement. Licensed machinists, pipefitters, and maintenance mechanics are the primary users of this tool.\u003c\/p\u003e\u003cp\u003eThis tap is used when threading large-bore pipe connections in industrial, commercial, and heavy mechanical applications. The 1-11\/2 NPS size is common in process piping, hydraulic manifolds, and large-diameter plumbing fittings where a precise, clean internal thread is required. It is suited for use in manual tapping setups or machine tapping operations where the operator controls speed and feed rate to match the workpiece material.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e1-11\/2 NPS thread standard for large-diameter pipe threading\u003c\/li\u003e\n\u003cli\u003eHigh-speed steel construction for durability across ferrous and non-ferrous workpiece materials\u003c\/li\u003e\n\u003cli\u003e5-flute design provides stable cutting and chip evacuation at this diameter\u003c\/li\u003e\n\u003cli\u003eBright, uncoated finish — no coating to interfere with close-tolerance thread fit\u003c\/li\u003e\n\u003cli\u003e1.75-inch thread length accommodates full-depth pipe thread engagement\u003c\/li\u003e\n\u003cli\u003e0.843-inch square drive for standard tap wrench or machine holder fitment\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in any tapping setup requiring 1-11\/2 NPS internal pipe threads, compatible with standard tap wrenches and machine tap holders sized for a 1.125-inch shank diameter.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThis tool is used by machinists, pipefitters, and maintenance mechanics in shop or field tapping operations. Ensure the workpiece is securely clamped and the pilot hole is drilled to the correct tap drill diameter for 1-11\/2 NPS before starting. Apply cutting fluid appropriate to the workpiece material throughout the threading operation to extend tool life and improve thread quality. Follow all applicable shop safety procedures and OSHA machine guarding requirements when operating tapping equipment.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: NPS\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1-11\/2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 5\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 1.75 inches\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: Bright\/Uncoated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHook\u003c\/strong\u003e: Regular\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.95 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23241600\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: VALUE COLLECTION\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: MSC-04665097\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51694575452466,"sku":"MSC-04665097","price":133.61,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/be85752b1313740172ce1c709bb8bc1c.jpg?v=1788325695","url":"https:\/\/voomisupply.com\/products\/value-collection-msc-04665097-pipe-tap-1-11-2-nps-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
