Built to the 16ER insert style, this solid carbide insert carries a TiC\/TiN coating and a manufacturer grade of HG630TR, combining substrate toughness with surface hardness for extended tool life in threading applications. It produces a partial profile 60-degree thread form and covers a pitch range of 0.50 mm to 3.00 mm (48 to 8 TPI), making it suitable for a broad range of unified and metric thread standards. The insert measures 3\/8 inch inscribed circle and 0.146 inches thick. Machinists and CNC operators in production and job shop environments are the primary users.\u003c\/p\u003e\n\u003cp\u003eThis insert is suited for right-hand external threading operations on steel, alloy steel, and similar machinable materials. The 60-degree partial profile geometry allows threading across multiple pitches without changing inserts, supporting flexible production setups. Typical install scenarios include high-volume threading on bar-fed lathes and manual threading passes on conventional turning machines where consistent thread form accuracy is required. The HG630TR grade and dual-layer coating support both wet and dry cutting conditions at moderate to high surface speeds.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide substrate with TiC\/TiN dual-layer coating for wear resistance and extended cutting life\u003c\/li\u003e\n  \u003cli\u003e60-degree partial profile thread form covers 48 to 8 TPI in a single insert\u003c\/li\u003e\n  \u003cli\u003eRight-hand external threading orientation for standard lathe setups\u003c\/li\u003e\n  \u003cli\u003e16ER insert style for compatibility with standard 16ER toolholders\u003c\/li\u003e\n  \u003cli\u003e3\/8 inch inscribed circle and 0.146 inch thickness for precise seating and repeatability\u003c\/li\u003e\n  \u003cli\u003eZero-degree relief angle (radial seating) for rigid, chatter-resistant laydown positioning\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a direct-fit replacement for 16ER-style threading insert seats used in standard external threading toolholders accepting a 3\/8 inch inscribed circle laydown insert.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by qualified machinists or CNC tooling technicians. Power down and lock out the machine spindle before indexing or replacing inserts. Use the correct torque wrench and insert screw per the toolholder manufacturer's specification to ensure proper seating without cracking the carbide. Inspect the insert pocket and clamping screw for wear or debris before installing a new insert.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\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\u003eCoating\/Finish\u003c\/strong\u003e: TiC\/TiN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Type\u003c\/strong\u003e: Right Hand External\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Form\u003c\/strong\u003e: 60 Degree Partial Profile\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThreads Per Inch (TPI)\u003c\/strong\u003e: 48-8\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePitch Range\u003c\/strong\u003e: 0.50 mm to 3.00 mm\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: 0.146 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRelief Angle\u003c\/strong\u003e: 0 degrees\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\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: H08702177\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51749735465266,"sku":"H08702177","price":233.56,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/504ec8f7cdbd2532091ef37a3f48e894.jpg?v=1788909738","url":"https:\/\/voomisupply.com\/products\/hertel-h08702177-threading-insert-16er-60-deg-48-8-tpi","provider":"Voomi Supply","version":"1.0","type":"link"}
