Manufactured from high speed steel with a titanium nitride (TiN) coating, this tap delivers extended tool life and reduced friction during threading operations. The 7-flute geometry provides improved chip evacuation and thread quality in a single pass. With a thread length of 1.75 inches and a short projection design, this tap is well suited for confined threading applications in pipe and plumbing work. Plumbers, pipefitters, and maintenance machinists use this tool in both shop and field settings.\u003c\/p\u003e\u003cp\u003eThis tap is intended for cutting standard NPT tapered pipe threads in metal pipe, pipe fittings, manifolds, and similar components. The 2 - 11-1\/2 designation indicates a 2-inch nominal pipe size with 11.5 threads per inch, following the National Pipe Taper standard. The short projection tap type makes it practical for restricted access locations. It is commonly used in industrial piping, HVAC hydronic systems, plumbing rough-in, and mechanical equipment installations requiring threaded pipe connections.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eNPT thread standard for tapered pipe thread cutting in standard pipe and fittings\u003c\/li\u003e\n\u003cli\u003eHigh speed steel construction provides durability in metal threading applications\u003c\/li\u003e\n\u003cli\u003eTiN coating reduces friction and extends tool service life compared to uncoated HSS\u003c\/li\u003e\n\u003cli\u003e7-flute design promotes efficient chip removal and clean thread form\u003c\/li\u003e\n\u003cli\u003eShort projection tap type suited for limited-clearance threading setups\u003c\/li\u003e\n\u003cli\u003e1.75-inch thread length accommodates full-depth NPT thread engagement\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in standard 2 - 11-1\/2 NPT tapered pipe thread applications in metal pipe, fittings, and mechanical components requiring National Pipe Taper threads.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThis tap is installed using a compatible tap wrench or machine holder sized for the 1.875-inch shank diameter. Secure the workpiece firmly before threading and apply appropriate cutting fluid for the material being tapped to prevent tool damage and ensure clean threads. Follow shop safety practices and wear appropriate eye and hand protection during all tapping operations. Verify thread class and fit with a pipe thread gauge after tapping to confirm proper seating before assembly.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\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: 2 - 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: 7\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTap Type\u003c\/strong\u003e: Short Projection\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 1.875 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSquare Size\u003c\/strong\u003e: 1.406 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProjection\u003c\/strong\u003e: 0.565 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: TiN (Titanium Nitride)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.06 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: R837537T\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51728570417458,"sku":"R837537T","price":1018.31,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/8e7dc2ddac932c47020c649fae34a3b4.jpg?v=1788693477","url":"https:\/\/voomisupply.com\/products\/hertel-r837537t-pipe-tap-2-11-2-npt-7-flutes-hss-tin","provider":"Voomi Supply","version":"1.0","type":"link"}
