Built from solid carbide in the IC908 grade and finished with a PVD-applied TiAlN coating, this insert delivers thermal resistance and wear performance across a broad range of workpiece materials. It carries a right-hand cutting orientation and fits toolholders accepting the 16IR insert style. The inscribed circle measures 3\/8 inches (9.53 mm) and the insert thickness is 0.143 inches. It is part of the ISCARTHREAD series and conforms to ISO 13399 standards for cutting tool data representation.\u003c\/p\u003e\n\u003cp\u003eThis insert is suited for internal threading operations on CNC lathes and turning centers where Stub Acme thread profiles are required. The Stub Acme thread form is commonly applied in power-transmission components, lead screws, and linear actuator hardware. The IC908 grade and TiAlN coating make it compatible with a universal range of workpiece materials, including steel, stainless steel, cast iron, non-ferrous alloys, and heat-resistant superalloys, as indicated by material codes H, K, M, N, P, and S.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eIC908 solid carbide grade with PVD TiAlN coating for extended tool life across universal workpiece materials\u003c\/li\u003e\n  \u003cli\u003e12 TPI internal Stub Acme thread form for right-hand cutting applications\u003c\/li\u003e\n  \u003cli\u003e16IR insert style with 3\/8-inch inscribed circle for standard ISCARTHREAD toolholder compatibility\u003c\/li\u003e\n  \u003cli\u003e0.143-inch insert thickness for stable laydown seating in the pocket\u003c\/li\u003e\n  \u003cli\u003eConforms to ISO 13399 cutting tool data standard\u003c\/li\u003e\n  \u003cli\u003eRight-hand cutting orientation for conventional internal threading operations\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement insert for 16IR-style internal threading toolholders within the ISCARTHREAD series accepting a 3\/8-inch inscribed circle.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified machinist or CNC tooling technician. Power down and lock out the machine spindle before seating or replacing inserts. Use the correct torx or clamping screw as specified by the toolholder manufacturer to secure the insert — do not overtighten. Inspect the pocket seating surface for chips or debris before installing a new insert to ensure proper contact and thread accuracy.\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: IC908\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: TiAlN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating Process\u003c\/strong\u003e: PVD\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: 12 TPI\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 inches (9.53 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 0.143 inches\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\u003eSeries\u003c\/strong\u003e: ISCARTHREAD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandard\u003c\/strong\u003e: ISO 13399\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.3 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Order Quantity\u003c\/strong\u003e: 5\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: ISCAR\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 5902302\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ISCAR","offers":[{"title":"Default Title","offer_id":51753435791666,"sku":"5902302","price":204.97,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/bf79e3c26c56c0063841975ed4d912aa.jpg?v=1788936758","url":"https:\/\/voomisupply.com\/products\/iscar-5902302-threading-insert-12-tpi-stub-acme-ic908","provider":"Voomi Supply","version":"1.0","type":"link"}
