Built from micrograin solid carbide and finished with a PVD-applied titanium nitride (TiN) coating, this insert delivers extended edge life and consistent thread form on demanding workpiece materials. The 3\/8-inch inscribed circle and 0.146-inch thickness conform to the 16IR indexable insert style standard. It is installed by machinists and CNC lathe operators in production and job-shop environments where precision Stub Acme internal threads are required.\u003c\/p\u003e\n\u003cp\u003eThis insert is suited for internal Stub Acme threading operations on a wide range of workpiece materials, including steel, stainless steel, cast iron, non-ferrous alloys, high-temperature alloys, and hardened materials  -  as reflected by its universal material grade coverage (H, K, M, N, P, S). Typical applications include threading bores on hydraulic cylinders, lead screws, power transmission components, and similar parts where the 29-degree included angle Stub Acme form is specified. The MXC manufacturer grade is engineered for versatility across this broad material spectrum.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid micrograin carbide substrate for sharp, stable cutting edges on internal threads\u003c\/li\u003e\n  \u003cli\u003ePVD TiN coating extends tool life and reduces built-up edge across multiple workpiece materials\u003c\/li\u003e\n  \u003cli\u003e14 TPI Stub Acme thread form with 29-degree included angle for accurate internal thread profiles\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut, 16IR laydown style for compatibility with standard 16IR boring bar toolholders\u003c\/li\u003e\n  \u003cli\u003e3\/8-inch inscribed circle (0.375 inches) and 0.146-inch thickness per insert style specification\u003c\/li\u003e\n  \u003cli\u003eMeets CE and ISO 13485:2016, ISO 14001:2015, and ISO 45001 standards\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in standard 16IR-style internal threading toolholders and boring bars that accept laydown threading inserts with a 3\/8-inch inscribed circle.

Use the correct torx or hex key at the recommended seating torque for the toolholder manufacturer's clamp system  -  do not overtighten, as this can fracture the carbide insert. Ensure the insert is fully seated in the pocket before resuming cutting operations, and inspect the thread form with a thread gauge after the first pass to confirm proper setup.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: 16IR\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Size Code\u003c\/strong\u003e: 16\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: Micrograin\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: MXC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Type\u003c\/strong\u003e: Internal\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: Stub Acme\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThreads Per Inch\u003c\/strong\u003e: 14 TPI\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eIncluded Angle\u003c\/strong\u003e: 29 degrees\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 (0.375 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 0.146 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: TiN (Titanium Nitride), PVD Applied\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Universal (H, K, M, N, P, S)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: CE, ISO 13485:2016, ISO 14001:2015, ISO 45001\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: 16IR14STACMEMXC\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CARMEX","offers":[{"title":"Default Title","offer_id":52023192092978,"sku":"16IR14STACMEMXC","price":290.37,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/339f10d9541c2cec91baf3f89ca960b5_4f770abe-7244-4189-ac7b-c9986132971c.jpg?v=1790013867","url":"https:\/\/voomisupply.com\/products\/carmex-16ir14stacmemxc-threading-insert-14-tpi-stub-acme","provider":"Voomi Supply","version":"1.0","type":"link"}
