Manufactured to a P30 grade with a C5 material classification, this insert features a 29-degree included angle and a right-hand cutting orientation. With a 3\/8-inch (0.3750 inch) inscribed circle and a thickness of 0.1460 inches, it is built for precision threading operations on a wide range of workpiece materials. Licensed machinists and CNC lathe operators use this insert for internal threading applications where consistent Acme thread form is required.\u003c\/p\u003e\n\u003cp\u003eThis insert is suited for internal Acme thread cutting across universal workpiece material categories, including ferrous metals, non-ferrous metals, stainless steels, heat-resistant alloys, and cast materials. The uncoated solid carbide construction makes it appropriate for applications where coating interaction with the workpiece is a concern or where regrinding may be needed. It is a right-hand insert intended for use in 16 IR-style laydown toolholders on CNC and manual lathes in both production and job-shop environments.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide construction at P30 grade for threading durability across universal material groups\u003c\/li\u003e\n  \u003cli\u003eInternal right-hand Acme thread form with 29-degree included angle\u003c\/li\u003e\n  \u003cli\u003e8 TPI thread pitch for standard Acme thread applications\u003c\/li\u003e\n  \u003cli\u003eUncoated finish allows use across a broad range of workpiece materials\u003c\/li\u003e\n  \u003cli\u003e3\/8-inch inscribed circle and 0.1460-inch thickness conform to 16 IR insert geometry standards\u003c\/li\u003e\n  \u003cli\u003eCompliant with 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 16 IR-style laydown threading toolholders.

Ensure the lathe spindle is fully stopped and the machine is in a safe, locked-out state before changing inserts. Verify correct insert orientation and thread hand before beginning a threading pass. Follow applicable shop safety procedures and machine tool manufacturer guidelines for insert replacement and thread-form verification.\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\u003eManufacturer Grade\u003c\/strong\u003e: P30\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: C5\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: 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\u003eInsert Hand\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eIncluded Angle\u003c\/strong\u003e: 29 degrees\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: 0.1460 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Uncoated\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: 16IR8ACMEP30\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CARMEX","offers":[{"title":"Default Title","offer_id":52073668903218,"sku":"16IR8ACMEP30","price":502.9,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/39e5d04fb39fb39d82e28763ce7ea67c.jpg?v=1790050608","url":"https:\/\/voomisupply.com\/products\/carmex-16ir8acmep30-laydown-threading-insert-8-tpi","provider":"Voomi Supply","version":"1.0","type":"link"}
