The interrupted thread geometry alternates cutting teeth with gaps, reducing torque, improving chip evacuation, and lowering the risk of tap breakage in difficult materials. The 5-flute configuration and high speed steel construction make it well-suited for production tapping in ferrous and non-ferrous materials. The bright (uncoated) finish is standard for general-purpose HSS taps. Overall length is 3.25 inches. This tool is used by machinists, pipefitters, and maintenance technicians who need precision NPTF pipe thread tapping.\u003c\/p\u003e\n\u003cp\u003eThe R867348-S produces NPTF tapered pipe threads that provide a pressure-tight mechanical seal without sealant, making it appropriate for hydraulic, pneumatic, fuel, and fluid system connections. It is suited for job shop and production environments where interrupted thread geometry reduces the chip-packing and galling that can occur when tapping blind holes or tough alloys. Typical applications include threading ports in manifolds, hydraulic blocks, fittings, and pipe flanges.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e3\/4-14 NPTF thread form produces pressure-tight tapered pipe threads\u003c\/li\u003e\n  \u003cli\u003eInterrupted thread design reduces torque and improves chip clearance\u003c\/li\u003e\n  \u003cli\u003e5-flute geometry increases cutting edges for smoother thread finish\u003c\/li\u003e\n  \u003cli\u003eHigh speed steel construction withstands heat generated in production tapping\u003c\/li\u003e\n  \u003cli\u003eBright finish suitable for use with a wide range of cutting fluids\u003c\/li\u003e\n  \u003cli\u003e3.25-inch overall length accommodates standard tap wrenches and machine holders\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in standard 3\/4-14 NPTF tapping applications.

Ensure the tap is started square to the hole to prevent cross-threading or tap breakage. For machine tapping, use a floating tap holder to compensate for minor misalignment. Follow shop safety protocols and wear appropriate eye protection when operating tapping equipment.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 3\/4-14\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: NPTF\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 5\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Type\u003c\/strong\u003e: Interrupted\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3.25 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: Bright (uncoated)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 2.94 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: R867348-S\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51748626104626,"sku":"R867348-S","price":114.82,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/3dcf7713324b79906173bd754556e689.jpg?v=1788895890","url":"https:\/\/voomisupply.com\/products\/hertel-r867348-s-3-4-14-nptf-pipe-tap-5-flute-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
