Made from solid carbide with a PVD-applied TiAlN coating, this insert delivers thermal resistance and edge hardness for threading in steel, stainless steel, and similar materials. It is configured for right-hand cutting and produces Whitworth-standard thread forms at 14 threads per inch (TPI). The 16ER insert style seats in standard laydown threading toolholders. Thickness is 0.1614 inches (4.10 mm), and the inscribed circle measures 3\/8 inch (0.3750 inches). This insert is used by machinists and toolroom technicians in production and job-shop environments.\u003c\/p\u003e\u003cp\u003eThis insert is suited for external threading passes on workpieces requiring British Standard Whitworth (BSW) thread forms. At 14 TPI, it is appropriate for larger Whitworth fastener profiles commonly encountered in maintenance, repair, and legacy equipment manufacturing. The solid carbide substrate and TiAlN finish make it a viable choice for interrupted cuts and moderate-to-high cutting speeds where high-speed steel tooling would degrade quickly. It is sold individually per package, with a minimum order quantity of 10 pieces.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide substrate for rigidity and wear resistance in threading applications\u003c\/li\u003e\n\u003cli\u003ePVD TiAlN coating provides thermal protection and extended tool life\u003c\/li\u003e\n\u003cli\u003eRight-hand external cut geometry for standard Whitworth threading passes\u003c\/li\u003e\n\u003cli\u003e14 TPI thread form matches British Standard Whitworth profiles\u003c\/li\u003e\n\u003cli\u003e16ER laydown insert style fits compatible indexable threading toolholders\u003c\/li\u003e\n\u003cli\u003eInscribed circle of 3\/8 inch (0.3750 inches) with 4.10 mm thickness\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in 16ER-style laydown indexable threading toolholders.

Power down and lock out the machine before indexing or replacing inserts. Use the correct torx or clamp screw driver to seat the insert fully and evenly in the pocket — do not overtighten. Verify thread form and TPI match the workpiece specification before beginning the threading cycle.\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: HG225TR\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: Whitworth\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\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: 16ERZ14WHG225TR\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51749677105458,"sku":"16ERZ14WHG225TR","price":322.36,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d8d07e9ef2046d2f333a00677de1d6b7.jpg?v=1788909088","url":"https:\/\/voomisupply.com\/products\/hertel-16erz14whg225tr-threading-insert-whitworth-14-tpi","provider":"Voomi Supply","version":"1.0","type":"link"}
