It features a TiC\/TiN coating that improves wear resistance and extends tool life in production threading applications. The insert uses a right-hand cutting orientation and seats in a laydown-style toolholder. With a 3\/8-inch inscribed circle and a thickness of 0.146 inches, it fits standard 16ER-style insert pockets. This insert is used by machinists and toolroom professionals running CNC lathes or manual threading operations where NPTF thread form accuracy is required.\u003c\/p\u003e\u003cp\u003eThis insert is suited for internal NPTF threading operations on pipe fittings, hydraulic components, and fluid-system parts that require a pressure-tight thread form. The NPTF (Dryseal) standard demands precise thread geometry to seal without a separate sealant compound, making insert grade and coating selection critical. The HG630TR grade solid carbide construction with TiC\/TiN finish handles the interrupted cuts and abrasive conditions common in ferrous and some non-ferrous threading work. Sold individually, with a minimum order quantity of 10 units.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide construction with TiC\/TiN coating for extended wear resistance\u003c\/li\u003e\n\u003cli\u003e11.5 TPI NPTF internal thread form for dryseal pipe thread applications\u003c\/li\u003e\n\u003cli\u003eRight-hand cutting orientation, laydown insert style (16ER)\u003c\/li\u003e\n\u003cli\u003e3\/8-inch inscribed circle fits standard 16ER toolholders\u003c\/li\u003e\n\u003cli\u003e0.146-inch insert thickness for consistent seating and repeatability\u003c\/li\u003e\n\u003cli\u003eRelief angle of 0 degrees, appropriate for laydown threading geometry\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in 16ER-style laydown threading toolholders that accept a 3\/8-inch inscribed circle insert with a 0.146-inch thickness and zero-degree relief angle.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by qualified machinists or toolroom technicians. Ensure the machine spindle is fully stopped and the toolholder is secured before seating or removing the insert. Use the correct torque wrench and insert screw for the toolholder manufacturer's specified clamping torque — do not overtighten. Inspect the insert pocket for chips or debris before seating to ensure proper insert contact and thread form accuracy.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: 16ER\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: HG630TR\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: NPTF\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Type\u003c\/strong\u003e: Internal\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Hand\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThreads Per Inch\u003c\/strong\u003e: 11.5 TPI\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 3\/8 inches (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\u003eCoating\/Finish\u003c\/strong\u003e: TiC\/TiN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.123 pounds\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: 10\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: H05766985\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51748693836082,"sku":"H05766985","price":265.24,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1e31edcc3ebf4bf10fcef79e389f8832.jpg?v=1788896839","url":"https:\/\/voomisupply.com\/products\/hertel-h05766985-threading-insert-11-5-tpi-nptf-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
