Built to Insert Style 16ER, this insert carries a P25C manufacturer grade and a C5 material grade, making it well-suited for general-purpose threading in steel and cast iron on CNC lathes and threading centers. The titanium nitride (TiN) coating is applied via PVD process to extend edge life and reduce built-up edge during continuous threading passes. With a 3\/8 inch inscribed circle and a thickness of 0.146 inches, the insert seats securely in compatible 16ER toolholders for repeatable thread profile accuracy.\u003c\/p\u003e\n\u003cp\u003eThis insert is intended for machinists and CNC operators producing Acme-profile external threads in production or job-shop environments. The Acme thread form is widely used in lead screws, power transmission components, vises, and linear actuators where load-carrying capacity and wear resistance are priorities. The 14 TPI pitch suits medium to coarse Acme thread applications across a range of workpiece diameters. The right-hand cutting orientation covers the majority of standard Acme threading jobs encountered in general machining operations.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide construction at P25C grade for reliable performance in steel and cast iron threading\u003c\/li\u003e\n  \u003cli\u003ePVD-applied TiN coating for extended tool life and reduced friction at the cutting edge\u003c\/li\u003e\n  \u003cli\u003e14 TPI Acme thread profile for external right-hand thread cutting\u003c\/li\u003e\n  \u003cli\u003e16ER insert style with 3\/8 inch inscribed circle for secure seating in standard 16ER holders\u003c\/li\u003e\n  \u003cli\u003e0.146 inch thickness provides consistent insert height and profile engagement\u003c\/li\u003e\n  \u003cli\u003eC5 material grade designation for cross-referencing with ISO and ANSI carbide grade charts\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in toolholders and threading bars accepting 16ER-style laydown threading inserts.

Power down and lock out the machine spindle before changing inserts. Seat the insert fully in the pocket and torque the clamping screw to the toolholder manufacturer specification using a calibrated torque wrench. Inspect the cutting edge for chips or coating damage before each use, and verify thread profile with a thread gauge after the first pass.\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\u003eThread Standard\u003c\/strong\u003e: Acme\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: 14 TPI\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Hand\u003c\/strong\u003e: Right Hand\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: P25C\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: C5\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: TiN\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: 3\/8 inches (0.3750 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 0.146 inches\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: CARMEX\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 16ER14ACMEP25C\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CARMEX","offers":[{"title":"Default Title","offer_id":67914541957426,"sku":"16ER14ACMEP25C","price":203.88,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/5525682385da9d33bd56a71baed960ad.jpg?v=1791249810","url":"https:\/\/voomisupply.com\/products\/carmex-16er14acmep25c-threading-insert-14-tpi-acme-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
