The insert features a right-hand cutting orientation and a 29-degree included angle consistent with the Acme thread standard. A PVD-applied titanium nitride (TiN) coating increases surface hardness and wear resistance. The inscribed circle measures 3\/8 inch (0.3750 inches) and the insert thickness is 0.1460 inches. This style is suited for CNC lathes and threading centers where a laydown-style insert holder is used, and it is installed by machinists and toolroom technicians in production and maintenance environments.\u003c\/p\u003e\n\u003cp\u003eThe 16IR8ACMEMXC is intended for internal Acme thread applications across a broad range of workpiece materials. The MXC micrograin carbide grade is rated for universal workpiece material compatibility, covering material codes H, K, M, N, P, and S. This makes it appropriate for threading steel, stainless steel, cast iron, non-ferrous metals, and high-temperature alloys. Typical applications include lead screws, power transmission components, jacks, and valve stems that require internal Acme thread profiles.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide construction in MXC micrograin grade for wear resistance across universal workpiece materials\u003c\/li\u003e\n  \u003cli\u003ePVD TiN coating improves edge hardness and extends tool life in production threading\u003c\/li\u003e\n  \u003cli\u003eRight-hand, internal Acme thread profile at 8 TPI with 29-degree included angle\u003c\/li\u003e\n  \u003cli\u003eLaydown insert style for use with compatible 16IR-series toolholders\u003c\/li\u003e\n  \u003cli\u003eInscribed circle of 0.3750 inches and thickness of 0.1460 inches for precise seating\u003c\/li\u003e\n  \u003cli\u003eCertified to CE, 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 16IR-series laydown threading insert holders.

Power down and lock out the machine before seating or replacing the insert. Use the appropriate torx or clamp-screw driver as specified by the toolholder manufacturer and do not overtighten the clamping screw. Inspect the insert pocket and seating surface for chips or debris before placing the insert to ensure proper contact and runout.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Type\u003c\/strong\u003e: Internal Acme\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThreads Per Inch\u003c\/strong\u003e: 8 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 Style\u003c\/strong\u003e: 16IR Laydown\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: MXC (Micrograin)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 0.3750 inches (3\/8 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 0.1460 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: TiN, PVD Applied\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Hand\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material Codes\u003c\/strong\u003e: H, K, M, N, P, S (Universal)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCertifications\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: 16IR8ACMEMXC\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CARMEX","offers":[{"title":"Default Title","offer_id":52100125065522,"sku":"16IR8ACMEMXC","price":336.37,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/79aff2dcf37d71b58da3dc41712e6bd9.jpg?v=1790068805","url":"https:\/\/voomisupply.com\/products\/carmex-16ir8acmemxc-threading-insert-8-tpi-3-8-in-ic-acme","provider":"Voomi Supply","version":"1.0","type":"link"}
