Manufactured from solid carbide with a PVD-applied TiN\/TiAlN coating, it carries the IC908 manufacturer grade, which targets universal workpiece materials including steels, cast irons, stainless, nonferrous alloys, and superalloys. The insert is rated for 12 threads per inch (TPI) on the UN thread standard and features a right-hand cutting orientation. The inscribed circle measures 9.53 mm (0.375 inches), thickness is 0.143 inches, and the corner radius is 0.25 mm (0.010 inches). Licensed machinists and CNC toolroom technicians install this insert in compatible laydown threading toolholders on turning centers and engine lathes.\u003c\/p\u003e\u003cp\u003eThis insert is suited for external UN threading passes on turned components in job shop, production machining, and maintenance-repair environments. The IC908 submicron carbide grade with PVD coating handles a broad range of workpiece materials, making it a practical choice when threading mild carbon steels, alloy steels, stainless steels, aluminum, and heat-resistant superalloys in a single tooling setup. It follows the 16ER insert style and is part of the ISCARTHREAD series. Standard package quantity is 1 insert; minimum order quantity is 5 units.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eIC908 submicron solid carbide grade with PVD TiN\/TiAlN coating for extended tool life across universal workpiece materials\u003c\/li\u003e\n\u003cli\u003e12 TPI UN external thread form, right-hand cut\u003c\/li\u003e\n\u003cli\u003e16ER insert style with 9.53 mm inscribed circle (3\/8 inch)\u003c\/li\u003e\n\u003cli\u003e0.143 inch insert thickness with 0.010 inch corner radius for controlled thread root geometry\u003c\/li\u003e\n\u003cli\u003eChipbreaker designation B for chip management during threading passes\u003c\/li\u003e\n\u003cli\u003eCompliant with ISO 13399 cutting tool data representation standard\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a laydown threading insert in the 16ER style for use in compatible ISCARTHREAD series toolholders and other toolholder systems that accept the 16ER seat geometry for external UN threading applications.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInsert installation and indexing should be performed by a qualified machinist or CNC toolroom technician with the machine in a fully stopped and locked-out state. Use the appropriate torque wrench and clamp screw specified by the toolholder manufacturer when seating the insert  -  do not over-tighten by hand estimation alone. Confirm thread form and pitch with a thread gauge after the first test pass before committing to full production runs. Handle carbide inserts with care to avoid chipping the cutting edge during installation.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: 16ER\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Size Code\u003c\/strong\u003e: 16\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UN\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: 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\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\u003eMaterial Grade\u003c\/strong\u003e: Submicron\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating Process\u003c\/strong\u003e: PVD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: TiN\/TiAlN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChipbreaker\u003c\/strong\u003e: B\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 9.53 mm (0.375 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 0.143 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.25 mm (0.010 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material Code\u003c\/strong\u003e: H; K; M; N; P; S\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: 0.025 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\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: 5993248\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ISCAR","offers":[{"title":"Default Title","offer_id":51740156035378,"sku":"5993248","price":184.24,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/322ae9551543a94d92e1d727db8ace1e.jpg?v=1788822976","url":"https:\/\/voomisupply.com\/products\/iscar-5993248-threading-insert-16er12un-ic908-12-tpi-un","provider":"Voomi Supply","version":"1.0","type":"link"}
