It carries a TiN (titanium nitride) finish that helps extend cutting life and reduce friction during the threading operation. The insert produces threads at 11.5 TPI, matching the standard NPT thread pitch used across pipe and fitting applications. With a 3\/8-inch inscribed circle and a thickness of 0.146 inches, this insert seats into compatible laydown-style toolholders used on CNC lathes and manual threading equipment. It is sold individually with a minimum order quantity of 50 pieces.\u003c\/p\u003e\u003cp\u003eThis insert is suited for internal NPT threading operations in production and job-shop environments. The NPT 11.5 TPI profile makes it a direct fit for threading standard pipe-size bores where a tapered thread form is required. Machinists working in metalworking, fluid-system component manufacturing, and industrial fitting production will find this insert applicable to a range of ferrous and non-ferrous materials where TiN-coated carbide tooling performs reliably.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide substrate with TiN finish for extended tool life\u003c\/li\u003e\n\u003cli\u003eRight-hand internal NPT thread form at 11.5 TPI\u003c\/li\u003e\n\u003cli\u003e3\/8-inch inscribed circle for laydown-style toolholder compatibility\u003c\/li\u003e\n\u003cli\u003e0.146-inch insert thickness for stable seating and accurate thread profile\u003c\/li\u003e\n\u003cli\u003eLaydown orientation simplifies indexing and insert changeover\u003c\/li\u003e\n\u003cli\u003eSold per piece with a minimum order quantity of 50\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a replacement-style laydown threading insert for CNC and manual lathes equipped with 16IR-series internal threading toolholders that accept a 3\/8-inch inscribed circle insert.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by qualified machinists or tooling technicians. Ensure the machine is powered down and the spindle is fully stopped before indexing or replacing inserts. Use the appropriate torx or clamp screw specified by the toolholder manufacturer to secure the insert - do not overtighten by hand estimation alone. Confirm thread profile and pitch with a thread gauge on the first test piece before running production.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Form\u003c\/strong\u003e: NPT (National Pipe Taper)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Direction\u003c\/strong\u003e: Right Hand Internal\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThreads Per Inch (TPI)\u003c\/strong\u003e: 11.5\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: Laydown\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 3\/8 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Thickness\u003c\/strong\u003e: 0.146 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSubstrate\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: TiN (Titanium Nitride)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMinimum Order Quantity\u003c\/strong\u003e: 50\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: CARMEX\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 16IR11.5NPTMXC\/G\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CARMEX","offers":[{"title":"Default Title","offer_id":68298111451442,"sku":"16IR11.5NPTMXC\/G","price":245.6,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/369f10428f14e2684c9f10cd4571fc38.jpg?v=1793706647","url":"https:\/\/voomisupply.com\/products\/carmex-16ir11-5nptmxc-g-threading-insert-npt-11-5-tpi","provider":"Voomi Supply","version":"1.0","type":"link"}
