Built from solid carbide with a TiC\/TiN multilayer coating, this insert delivers consistent thread form and extended tool life in production and job-shop turning operations. The 16ER insert style seats securely in compatible laydown-style toolholders, and the right-hand orientation makes it suited to standard external threading passes on a CNC or manual lathe. Machinists and toolroom operators use this insert when accuracy and repeatability across UN-standard thread profiles are required.\u003c\/p\u003e\n\u003cp\u003eThis insert is intended for external threading operations conforming to the UN thread standard at 12 TPI. The 3\/8-inch inscribed circle and 0.146-inch thickness fit the 16ER insert pocket geometry. Typical applications include threading steel and alloy workpieces in manufacturing, maintenance, and repair environments where a right-hand external UN thread form must be held to standard tolerances. The solid carbide substrate handles interrupted cuts and harder workpiece materials better than high-speed steel alternatives.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide substrate with TiC\/TiN coating for wear resistance and extended edge life\u003c\/li\u003e\n  \u003cli\u003e16ER insert style for laydown-style external threading toolholders\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut for standard external UN thread profiles\u003c\/li\u003e\n  \u003cli\u003e12 TPI thread pitch for common UN fastener and fitting threads\u003c\/li\u003e\n  \u003cli\u003e3\/8-inch inscribed circle with a 0.146-inch thickness\u003c\/li\u003e\n  \u003cli\u003eZero-degree relief angle for laydown seating geometry\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in 16ER-style laydown threading toolholders configured for external right-hand UN thread cutting at 12 TPI.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInsert installation should be performed by a qualified machinist with the lathe or turning center powered down and the spindle locked. Use the correct torque wrench and insert screw specified by the toolholder manufacturer  -  do not overtighten, as carbide inserts can crack under excessive clamping force. Confirm insert seating and pocket cleanliness before engaging the workpiece. Follow the toolholder manufacturer guidelines for insert indexing and replacement intervals.\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: HG330TR\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: TiC\/TiN\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: External\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThreads Per Inch\u003c\/strong\u003e: 12\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Hand\u003c\/strong\u003e: Right Hand\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\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: H08707192\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51773394354482,"sku":"H08707192","price":232.32,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/157a7ba4174ab8a3d7fe9690e1ae56a5.jpg?v=1789162911","url":"https:\/\/voomisupply.com\/products\/hertel-h08707192-threading-insert-12-tpi-3-8-in-ic-un","provider":"Voomi Supply","version":"1.0","type":"link"}
