The interrupted thread geometry — alternating cutting teeth with gaps — reduces friction and chip packing during the tapping operation, making it well suited for tougher materials and deeper thread engagement. Constructed from high-speed steel (HSS), this tap maintains cutting-edge hardness under heat generated during threading. With 7 flutes and a bright uncoated finish, it delivers consistent thread form on NPT-standard pipe fittings and couplings used across plumbing, HVAC, and industrial piping installations.\u003c\/p\u003e\u003cp\u003eThis tap is used by pipefitters, plumbers, and machinists tapping large-diameter pipe threads in ferrous and non-ferrous metals. The 1-1\/2 - 11-1\/2 NPT specification matches standard tapered pipe thread requirements for schedule pipe, fittings, valves, and manifold bodies found in commercial and industrial plumbing, gas distribution, and HVAC hydronic systems. It is driven using a tap wrench or machine tapping setup sized for the 1-1\/2 inch shank diameter.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eInterrupted thread design reduces friction and chip buildup in blind or deep-thread applications\u003c\/li\u003e\n\u003cli\u003eHigh-speed steel construction resists heat and maintains edge hardness through extended use\u003c\/li\u003e\n\u003cli\u003e7-flute configuration provides better chip evacuation compared to standard 4-flute pipe taps\u003c\/li\u003e\n\u003cli\u003eBright uncoated finish suited for use with cutting oil or tapping fluid on most metals\u003c\/li\u003e\n\u003cli\u003eRegular hook geometry compatible with both hand and machine tapping setups\u003c\/li\u003e\n\u003cli\u003eNPT taper thread standard ensures pressure-tight pipe joint compatibility\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for cutting 1-1\/2 - 11-1\/2 NPT tapered pipe threads as an OEM-style tooling option for standard pipe tapping operations in plumbing, HVAC, and industrial piping applications.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThis tap is installed and operated by qualified pipefitters, plumbers, or machinists familiar with pipe thread cutting procedures. Always apply a suitable cutting fluid or tapping oil before and during the threading operation to extend tool life and improve thread finish. Secure the workpiece fully before applying torque, and back off the tap periodically to clear chips and prevent binding. Follow applicable plumbing and piping codes, including IPC and IFGC, for thread engagement requirements on pressure-carrying pipe joints.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1-1\/2 - 11-1\/2 NPT\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: NPT\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 7\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\u003eOverall Length\u003c\/strong\u003e: 4-1\/4 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 1-3\/4 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 1.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSquare Size\u003c\/strong\u003e: 1.125 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1.5 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-04663118\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51690750804274,"sku":"MSC-04663118","price":282.87,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/b65aca98dc4da327599514d44f309d0e.jpg?v=1788274970","url":"https:\/\/voomisupply.com\/products\/value-collection-msc-04663118-pipe-tap-1-1-2-11-1-2-npt-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
