Built from high speed steel (HSS), this tap produces a 2 - 11-1\/2 NPS thread form across a 1.75 inch thread length. Seven flutes provide clean chip evacuation and consistent thread geometry. The bright, uncoated finish makes it compatible with a wide range of cutting fluids. This tool is used by plumbers, pipefitters, and machinists threading pipe fittings, manifolds, and mechanical housings in trade and industrial settings.\u003c\/p\u003e\n\u003cp\u003eThis pipe tap is suited for threading ferrous and non-ferrous materials where a standard NPS thread profile is required. Typical applications include threading pipe ports in hydraulic and pneumatic manifolds, fabricating threaded fittings, and maintenance work on mechanical systems. The 2 - 11-1\/2 NPS designation means a 2 inch nominal pipe size with 11.5 threads per inch. The shank diameter of 1.875 inches and square drive size of 1.406 inches are sized for use with standard tap wrenches or machine holders appropriate for large-diameter taps.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e2 - 11-1\/2 NPS thread form for standard pipe connections\u003c\/li\u003e\n  \u003cli\u003eHigh speed steel construction for durability across a range of materials\u003c\/li\u003e\n  \u003cli\u003e7 flutes for efficient chip clearance and consistent thread cutting\u003c\/li\u003e\n  \u003cli\u003e1.75 inch thread length suitable for full pipe thread engagement\u003c\/li\u003e\n  \u003cli\u003eBright uncoated finish compatible with most cutting fluids\u003c\/li\u003e\n  \u003cli\u003e1.875 inch shank diameter fits standard large-tap holders and wrenches\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or direct-use pipe tap for applications requiring a 2 - 11-1\/2 NPS thread standard in ferrous and non-ferrous workpieces.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003ePipe taps of this size are typically installed by pipefitters, machinists, or plumbers using a heavy-duty tap wrench or machine tapping setup. Always apply appropriate cutting fluid for the workpiece material to extend tool life and improve thread quality. Secure the workpiece firmly before threading to prevent movement. Reverse the tap periodically during use to break and clear chips, especially in deeper holes.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\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: 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\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\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\u003eWeight\u003c\/strong\u003e: 0.06 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: R843770-S\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51732514046258,"sku":"R843770-S","price":452.25,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/992ee52d50daba1f332bf0562d968470.jpg?v=1788743843","url":"https:\/\/voomisupply.com\/products\/hertel-r843770-s-pipe-tap-2-11-2-nps-7-flute-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
