Built from solid carbide with a TiC\/TiN finish, it delivers the hardness and wear resistance required for production threading in ferrous and non-ferrous materials. The insert features a right-hand cutting orientation, 8 threads per inch, a 3\/8 inch inscribed circle, and a 0.146 inch thickness. The 16IR style geometry seats in compatible laydown insert toolholders and maintains profile accuracy across repeated passes. Licensed machinists and CNC operators working in pipe fitting, valve, and fluid-handling component production are the primary users of this insert.\u003c\/p\u003e\u003cp\u003eThis insert is suited for threading internal NPT taper pipe threads in production and job-shop environments. It handles residential and commercial pipe thread applications where a consistent, leak-free thread form is required. The 8 TPI pitch corresponds to NPT thread sizing on common pipe diameters such as 3\/8 inch and 1\/2 inch nominal pipe. The solid carbide substrate and dual-layer TiC\/TiN coating extend tool life in interrupted or continuous internal threading cuts.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide substrate with TiC\/TiN coating for extended wear resistance\u003c\/li\u003e\n\u003cli\u003eRight-hand internal NPT thread profile at 8 TPI\u003c\/li\u003e\n\u003cli\u003e16IR insert style fits standard laydown threading toolholders\u003c\/li\u003e\n\u003cli\u003e3\/8 inch inscribed circle and 0.146 inch thickness for consistent toolholder seating\u003c\/li\u003e\n\u003cli\u003eZero-degree relief angle laydown geometry for rigid, chatter-resistant threading\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement insert for 16IR-style laydown threading toolholders used in internal NPT thread applications.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by a machinist or CNC operator. Power down and lock out the machine spindle before seating or removing the insert. Use the correct torx or hex key torque driver as specified by the toolholder manufacturer to clamp the insert — do not overtighten by hand estimate. Verify insert seating and profile alignment before initiating a threading pass to avoid thread form errors or premature insert failure.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: 16IR\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: TiC\/TiN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Type\u003c\/strong\u003e: Internal NPT\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThreads Per Inch\u003c\/strong\u003e: 8\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Hand\u003c\/strong\u003e: Right Hand\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\u003eThickness\u003c\/strong\u003e: 0.1460 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRelief Angle\u003c\/strong\u003e: 0 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.123 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: H08713794\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51733023949106,"sku":"H08713794","price":266.2,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/fabae9696728b73dfefebc1d0bee8128.jpg?v=1788750666","url":"https:\/\/voomisupply.com\/products\/hertel-h08713794-threading-insert-8-tpi-npt-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
