Built to insert style 11IR, this insert features a TiC\/TiN multilayer coating that improves wear resistance and extends tool life in demanding threading applications. It carries a 1\/4-inch inscribed circle and measures 0.127 inches in thickness, with a relief angle of 0 degrees. Manufactured to the HG330TR grade, it suits precision threading operations where consistent thread form and surface finish are required. HVAC, plumbing, and general mechanical contractors rely on inserts like this for internal threading on pipe fittings, valves, and machined components.\u003c\/p\u003e\u003cp\u003eThis insert is suited for internal threading on UN-standard fastener and fitting profiles in both production and maintenance machining environments. It is appropriate for use in CNC lathes and manual threading setups where a laydown-style insert seat is specified. The 36 TPI designation targets fine-pitch threading applications common in instrument fittings, hydraulic connectors, and precision mechanical assemblies. Each package contains one insert, 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 life\u003c\/li\u003e\n\u003cli\u003e36 TPI for fine-pitch UN internal threading\u003c\/li\u003e\n\u003cli\u003e1\/4-inch inscribed circle fits standard 11IR toolholders\u003c\/li\u003e\n\u003cli\u003e0.127-inch insert thickness for consistent seating depth\u003c\/li\u003e\n\u003cli\u003eRight-hand cutting geometry for standard lathe threading passes\u003c\/li\u003e\n\u003cli\u003eHG330TR grade optimized for steel and general-purpose threading materials\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or direct-fit insert for toolholders accepting 11IR-style laydown threading inserts with a 1\/4-inch inscribed circle and 0.127-inch thickness seating requirement.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified machinist or tooling technician familiar with indexable insert toolholders. Power down and lock out the machine spindle before seating or replacing inserts. Ensure the insert pocket is clean and free of chips before clamping to maintain proper seating. Follow the toolholder manufacturer torque and clamping recommendations for 11IR-style inserts.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: 11IR\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UN\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: 36 TPI\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 0.250 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\u003eRelief Angle\u003c\/strong\u003e: 0 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: TiC\/TiN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: HG330TR\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\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.123 pounds\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: H08704090\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51729591009586,"sku":"H08704090","price":275.92,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/a53427854ac40d27d2a7aee71ead32fd.jpg?v=1788706487","url":"https:\/\/voomisupply.com\/products\/hertel-h08704090-threading-insert-36-tpi-1-4-in-ic","provider":"Voomi Supply","version":"1.0","type":"link"}
