Built from solid carbide with a TiAlN PVD coating, this insert carries ISCAR grade IC908 and is engineered for right-hand external threading operations. It features a 3\/8-inch (0.375 inch) inscribed circle and a thickness of 0.143 inches. The IC908 grade is suited for a wide range of workpiece materials, making it a practical choice for shops cutting UN-standard threads across varied stock. Machinists and CNC lathe operators running production or toolroom work will find this insert fits the ISCARTHREAD series toolholding system.\u003c\/p\u003e\u003cp\u003eThis insert is intended for external UN threading applications on CNC lathes and manual turning centers. It is rated for use across multiple material groups including steel, stainless steel, cast iron, non-ferrous metals, high-temperature alloys, and hardened materials, corresponding to ISO material codes H, K, M, N, P, and S. The M chipbreaker geometry and PVD TiAlN coating support consistent chip control and tool life across these material grades. It is sold in a minimum order quantity of 5 inserts, with each package containing 1 insert.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide construction with PVD TiAlN coating for wear resistance across multiple material groups\u003c\/li\u003e\n\u003cli\u003eISCAR IC908 manufacturer grade rated for ISO material groups H, K, M, N, P, and S\u003c\/li\u003e\n\u003cli\u003eRight-hand external UN thread profile at 13 TPI\u003c\/li\u003e\n\u003cli\u003e16ERM insert style, 3\/8-inch inscribed circle, 0.143 inches thick\u003c\/li\u003e\n\u003cli\u003eM chipbreaker geometry for controlled chip evacuation during threading passes\u003c\/li\u003e\n\u003cli\u003eConforms to ISO 13399 cutting tool data standards\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in ISCARTHREAD series toolholders accepting 16ERM-style laydown threading inserts with a 3\/8-inch inscribed circle.

Use the appropriate torx or clamping screw driver specified for the toolholder to secure the insert without overtightening. Inspect the toolholder pocket for wear or debris before seating the new insert. Handle carbide inserts carefully to avoid chipping the cutting edge prior to use.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: 16ERM\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, PVD Coated\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: 13\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Hand\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChipbreaker\u003c\/strong\u003e: M\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 0.375 inches (3\/8 inch)\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: 0.24 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eISO Material Codes\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\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\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.01 pounds\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: 5902339\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ISCAR","offers":[{"title":"Default Title","offer_id":51736503419186,"sku":"5902339","price":150.71,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/8b94ee486eea5e63458c0d37dab6163b.jpg?v=1788778298","url":"https:\/\/voomisupply.com\/products\/iscar-5902339-threading-insert-16erm-13-un-ic908-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
