It carries an 18 TPI pitch, a 60-degree included angle, and a 3\/8-inch (0.3750-inch) inscribed circle, making it a standard 3ER-style insert. The TiAlN coating is applied via PVD process, delivering high surface hardness and heat resistance for demanding threading operations. The SCB chipbreaker geometry supports reliable chip control across a wide range of workpiece materials. This insert is suited for machinists and tooling technicians running production or repair threading in shops, field service environments, or manufacturing facilities.\u003c\/p\u003e\n\u003cp\u003eThis insert is used for right-hand external NPT thread milling and turning applications across universal workpiece materials, including steel, stainless steel, cast iron, non-ferrous metals, and high-temperature alloys, as reflected by the primary material codes H, K, M, N, P, and S. The NPT thread standard makes it applicable to pipe fitting and fluid system component threading in plumbing, HVAC, and industrial piping production. It fits standard 3ER insert pockets and is sold individually, with a minimum order quantity of 10 units per purchase.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide construction for rigidity and wear resistance in threading operations\u003c\/li\u003e\n  \u003cli\u003eTiAlN coating via PVD process improves heat and abrasion resistance\u003c\/li\u003e\n  \u003cli\u003e18 TPI with 60-degree included angle for accurate NPT thread form\u003c\/li\u003e\n  \u003cli\u003e3\/8-inch (0.3750-inch) inscribed circle fits standard 3ER insert pockets\u003c\/li\u003e\n  \u003cli\u003eSCB chipbreaker geometry supports chip control across universal workpiece materials\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut, external thread orientation for standard pipe thread applications\u003c\/li\u003e\n  \u003cli\u003eConforms to ANSI B1.1:74 and manufactured under ISO 9001:2008 quality standards\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a direct-fit replacement for standard 3ER-style laydown threading insert pockets used in external NPT threading applications.

Power down and lock out the machine before seating or replacing the insert. Ensure the insert pocket is clean and free of debris before seating to maintain proper thread form geometry. Follow the machine manufacturer torque guidance for the clamping screw to avoid insert movement or pocket damage during cuts.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: 3ER\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Size Code\u003c\/strong\u003e: 3\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: VCB\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThreads Per Inch\u003c\/strong\u003e: 18 TPI\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Type\u003c\/strong\u003e: External\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: NPT\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Hand\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eIncluded Angle\u003c\/strong\u003e: 60 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChipbreaker\u003c\/strong\u003e: SCB\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 3\/8 inch (0.3750 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: TiAlN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating Process\u003c\/strong\u003e: PVD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material Codes\u003c\/strong\u003e: H, K, M, N, P, S (Universal)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: Standard\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: ANSI B1.1:74, ISO 9001:2008\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.1 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: VARGUS\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 53686\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VARGUS","offers":[{"title":"Default Title","offer_id":67907872358706,"sku":"53686","price":314.59,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/71b1490e4175c7ed9a705848ea6ab931_6718f293-d076-416c-a5ff-273c59a1a327.jpg?v=1791181702","url":"https:\/\/voomisupply.com\/products\/vargus-53686-threading-insert-18-tpi-3-8-inch-ic-npt","provider":"Voomi Supply","version":"1.0","type":"link"}
