Part of the CoroTap 300 series, it features 4 flutes and a high-speed steel (HSS) construction with a steam tempered finish that improves lubricity and resistance to wear. The shank diameter measures 0.562 inches, and the overall length is 100 millimeters (approximately 3.94 inches), with a thread length of 0.787 inches. This tap is suited for machinists, pipefitters, and maintenance technicians who need accurate NPT threads for pressure-rated piping connections in production or field repair settings.\u003c\/p\u003e\n\u003cp\u003eThis tap is used to cut 1\/4-18 NPT internal pipe threads in ferrous and non-ferrous metals. The NPT thread standard is common in plumbing, HVAC, pneumatic, and hydraulic systems where tapered threads provide a pressure-tight seal. The extension-style design allows access to recessed or difficult-to-reach bores where standard-length taps cannot reach. It is appropriate for both manual and machine tapping operations in light manufacturing and maintenance environments.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e1\/4-18 NPT tapered thread form for pressure-rated pipe connections\u003c\/li\u003e\n  \u003cli\u003e4-flute geometry for balanced chip evacuation and thread quality\u003c\/li\u003e\n  \u003cli\u003eHigh-speed steel construction provides toughness across a range of workpiece materials\u003c\/li\u003e\n  \u003cli\u003eSteam tempered finish reduces friction and improves tap life\u003c\/li\u003e\n  \u003cli\u003e0.562-inch shank diameter compatible with standard tap holders and chucks\u003c\/li\u003e\n  \u003cli\u003eCoroTap 300 series design for consistent thread accuracy\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for cutting 1\/4-18 NPT internal tapered pipe threads; compatible with standard tap holders accepting a 0.562-inch shank diameter.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003ePipe taps are installed by machinists or pipefitters using a tap wrench, drill press, or CNC tapping machine. Always ensure the workpiece is securely clamped and the pilot hole is drilled to the correct tap drill size for 1\/4-18 NPT before threading. Apply a suitable cutting fluid throughout the tapping operation to extend tap life and improve thread finish. Inspect threads with a go\/no-go NPT thread gauge after tapping to verify compliance with the required thread standard.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1\/4-18 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: 4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 0.787 inches (20.00 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3.94 inches (100.00 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.562 inches (14.27 mm)\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: Steam Tempered\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: CoroTap 300\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.244 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23241600\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: SANDVIK COROMANT\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 6967077\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SANDVIK COROMANT","offers":[{"title":"Default Title","offer_id":51754761224498,"sku":"6967077","price":65.65,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/2dd4e9a3c86721de7682732ef42244ec_0e501e19-536d-4fc5-af19-9f449b2aa063.jpg?v=1788948519","url":"https:\/\/voomisupply.com\/products\/sandvik-coromant-6967077-extension-pipe-tap-1-4-18-npt","provider":"Voomi Supply","version":"1.0","type":"link"}
