Built from solid carbide with a PVD-applied TiAlN coating, this insert delivers the hardness and thermal resistance required for high-speed threading operations in steel, stainless, and alloy materials. It carries a 3\/8-inch inscribed circle, runs at 14 threads per inch, and measures 0.1614 inches thick. The HG225TR grade designation indicates a tough carbide substrate optimized for threading applications where edge stability and wear resistance are the primary demands. Machinists and CNC operators in precision machining, oil and gas, and general metalworking environments are the primary users of this insert.\u003c\/p\u003e\n\u003cp\u003eThis insert is designed for external NPT threading operations where a tapered pipe thread form is required. The 16ER insert style seats in compatible 16ER-series laydown toolholders. Applications include threading pipe fittings, hydraulic adapters, pneumatic ports, and other components requiring a standard NPT tapered thread profile. The right-hand cutting geometry suits conventional lathe rotation for the majority of standard threading cycles. This insert is sold individually and requires a minimum order quantity of 10 units.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide substrate with PVD TiAlN coating for elevated wear resistance and heat dissipation\u003c\/li\u003e\n  \u003cli\u003e14 TPI NPT thread form for standard tapered pipe thread cutting\u003c\/li\u003e\n  \u003cli\u003e3\/8-inch inscribed circle in the 16ER laydown insert style\u003c\/li\u003e\n  \u003cli\u003eRight-hand external cutting geometry for conventional lathe threading cycles\u003c\/li\u003e\n  \u003cli\u003eHG225TR manufacturer grade optimized for threading stability and edge life\u003c\/li\u003e\n  \u003cli\u003eThickness of 0.1614 inches for precise seating in compatible 16ER toolholders\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in 16ER-series laydown threading toolholders.

Power down and lock out the machine spindle before seating or replacing the insert. Use the correct torque wrench and insert screw per the toolholder manufacturer specifications to avoid cracking the carbide. Inspect the insert pocket and clamping screw for wear or debris before seating 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: HG225TR\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: NPT\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Type\u003c\/strong\u003e: External\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: 14\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: 0.1614 inches (4.10 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\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\u003eWeight\u003c\/strong\u003e: 0.01 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: 16ERZ14NPTHG225\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51737102385458,"sku":"16ERZ14NPTHG225","price":274.13,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1a3c8c0f08b16d846b2ca963fc42f9c6.jpg?v=1788784265","url":"https:\/\/voomisupply.com\/products\/hertel-16erz14npthg225-threading-insert-14-tpi-npt-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
