Built from high speed steel, it withstands the heat and friction generated during tapping operations in steel, cast iron, and similar ferrous materials. The 6-inch overall length provides the reach needed for deep or recessed applications. With 5 flutes and an interrupted thread design, the tap breaks chips efficiently and reduces the risk of chip packing in blind or deep holes. Licensed pipe fitters, plumbers, and mechanical contractors use this tap when reworking pipe connections or tapping new ports in HVAC and plumbing assemblies.\u003c\/p\u003e\n\u003cp\u003eThis extension pipe tap is suited for residential and commercial applications where 3\/8-18 NPT threaded connections are required. Typical use cases include tapping new ports in manifolds, reworking corroded or damaged threads in pipe bodies, and cutting threads in locations that standard pipe taps cannot access due to depth or obstructions. The 1-1\/16-inch thread length provides adequate engagement for a full NPT taper thread form. The tool is used handheld with a tap wrench or in a drill press setup depending on access conditions.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e3\/8-18 NPT thread size for standard pipe thread applications\u003c\/li\u003e\n  \u003cli\u003e6-inch overall length for extended reach in deep or recessed ports\u003c\/li\u003e\n  \u003cli\u003e5-flute design promotes efficient chip evacuation\u003c\/li\u003e\n  \u003cli\u003eInterrupted thread geometry reduces chip packing and cutting torque\u003c\/li\u003e\n  \u003cli\u003eHigh speed steel construction provides heat and wear resistance\u003c\/li\u003e\n  \u003cli\u003e1-1\/16-inch thread length delivers full NPT taper engagement\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for cutting 3\/8-18 NPT internal threads in ferrous and non-ferrous materials where an extended-reach pipe tap is required. Verify workpiece material compatibility with high speed steel tooling before use.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003ePipe taps should be used by qualified tradespeople familiar with thread cutting procedures. Secure the workpiece before tapping and use cutting fluid appropriate for the base material to extend tool life and improve thread quality. Apply steady, even torque with a calibrated tap wrench and back off periodically to break and clear chips, especially in deeper holes. Inspect threads after tapping with a go\/no-go gauge to confirm proper fit before assembly.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 3\/8-18\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: 5\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInterrupted Thread\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 1-1\/16 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 6 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: High Speed Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1.1 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: R867352-S\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51730213929266,"sku":"R867352-S","price":169.68,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/347031c44af673792d59dbeecb7b81e2.jpg?v=1788713468","url":"https:\/\/voomisupply.com\/products\/hertel-r867352-s-extension-pipe-tap-3-8-18-npt-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
