Built to the 11 ER insert style, it cuts right-hand threads at 40 threads per inch (TPI) and features a TiAlN coating applied via PVD process. The TiAlN finish improves heat resistance and tool life in demanding threading applications. With a 0.25 inch inscribed circle and 0.127 inch thickness, this insert fits standard 11 ER toolholders. It is used by machinists and CNC operators working to aerospace and precision fastener thread standards.\u003c\/p\u003e\n\u003cp\u003eThis insert is suited for threading operations requiring UNJ thread form compliance, which specifies a controlled root radius for improved fatigue resistance in critical fastener applications. Typical use cases include aerospace component manufacturing, precision shaft threading, and high-strength fastener production where UNJ thread standards are specified. The right-hand cutting geometry and PVD TiAlN coating make it a strong choice for stainless steel, alloy steel, and other challenging workpiece materials. Sold individually with a minimum order quantity of 10 pieces.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide substrate with PVD TiAlN coating for extended tool life and heat resistance\u003c\/li\u003e\n  \u003cli\u003e40 TPI right-hand external UNJ thread form for aerospace and precision fastener applications\u003c\/li\u003e\n  \u003cli\u003e11 ER insert style with 0.25 inch inscribed circle fits standard compatible toolholders\u003c\/li\u003e\n  \u003cli\u003e0.127 inch insert thickness provides a rigid, stable cutting platform\u003c\/li\u003e\n  \u003cli\u003eManufacturer grade HG225TR indicating a coated fine-grain carbide formulation\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or direct-fit insert for toolholders accepting the 11 ER laydown threading insert style with a 0.25 inch inscribed circle.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by CNC machinists or tool-and-die professionals. Power down and lock out the machine spindle before seating or removing inserts. Use the correct torx or hex key to the toolholder manufacturer's specified clamping method — do not overtighten the clamp screw, as carbide inserts can fracture under excess clamping force. Verify insert seating and thread pitch setup against a thread gauge before running production.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: 11 ER\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 Type\u003c\/strong\u003e: External\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNJ\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThreads Per Inch\u003c\/strong\u003e: 40 TPI\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Hand\u003c\/strong\u003e: Right Hand\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\u003eInscribed Circle\u003c\/strong\u003e: 0.25 inches (1\/4 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 0.127 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHeight\u003c\/strong\u003e: 0.2 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 0.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 0.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.2 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: 11ER40UNJHG225T\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51747404153138,"sku":"11ER40UNJHG225T","price":343.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/2493fb5be64f0dbd3479e3d8c57e3f49.jpg?v=1788879574","url":"https:\/\/voomisupply.com\/products\/hertel-11er40unjhg225t-threading-insert-40-tpi-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
