Manufactured to the GFN 2J geometry with an IC908 PVD-coated grade, this single-end insert delivers a 1.99 mm cutting width and a neutral lead angle for straight, balanced cuts. The IC908 coating provides wear resistance across a broad range of workpiece materials. The J chipbreaker geometry promotes chip control in grooving and parting applications. This insert is part of the Self-Grip series and is installed by machinists and toolroom technicians working in production or job-shop environments.\u003c\/p\u003e\u003cp\u003eThis insert is suited for grooving and parting operations in both production and job-shop turning setups. Its universal primary workpiece material rating covers a wide range of metals, including steel, stainless steel, cast iron, and high-temperature alloys, corresponding to ISO material groups P, M, K, H, and S. The Self-Grip series clamping method secures the insert directly in compatible Self-Grip toolholders without additional hardware, allowing fast indexing during high-volume runs.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eIC908 PVD-coated carbide grade for extended tool life across universal workpiece materials\u003c\/li\u003e\n\u003cli\u003e1.99 mm cutting width with a neutral lead angle for straight parting and grooving cuts\u003c\/li\u003e\n\u003cli\u003eJ chipbreaker geometry for effective chip control in grooving applications\u003c\/li\u003e\n\u003cli\u003eSelf-Grip clamping method for secure, tool-free insert seating in compatible holders\u003c\/li\u003e\n\u003cli\u003e7-degree relief angle reduces flank wear and supports clean exit cuts\u003c\/li\u003e\n\u003cli\u003e0.16 mm corner radius for controlled entry and reduced notching at groove shoulders\u003c\/li\u003e\n\u003cli\u003eCompliant with ISO 13399 tooling data standards for integration with CAM and tool management systems\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in ISCAR Self-Grip series toolholders that accept GFN 2-size inserts.

Use the appropriate ISCAR Self-Grip clamping tool to seat and release the insert; do not use improvised tools that may damage the pocket or insert body. Inspect the toolholder pocket for wear, debris, or damage before seating a new insert. Follow the machine tool manufacturer and cutting tool manufacturer guidelines for feed rates and depth of cut when setting up grooving or parting operations.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: GFN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Size Code\u003c\/strong\u003e: 2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: IC908\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Material\u003c\/strong\u003e: Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Width\u003c\/strong\u003e: 1.99 mm (0.0783 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLead Angle Direction\u003c\/strong\u003e: Neutral\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Hand\u003c\/strong\u003e: Neutral\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRelief Angle\u003c\/strong\u003e: 7 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.16 mm (0.0063 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChipbreaker\u003c\/strong\u003e: J\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: Coated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Holding Method\u003c\/strong\u003e: Clamp (Self-Grip)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Tool Application\u003c\/strong\u003e: Grooving, Parting\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Universal (ISO Groups H, K, M, P, S)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: C1, C2, C6, C7\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSingle or Double End\u003c\/strong\u003e: Single\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: Self-Grip\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: 0.03 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: 6003139\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ISCAR","offers":[{"title":"Default Title","offer_id":51727184232754,"sku":"6003139","price":243.59,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/33f5c7ddb591e70c5ae2d5ce43248ed1.jpg?v=1788674438","url":"https:\/\/voomisupply.com\/products\/iscar-6003139-gfn-2j-ic908-carbide-cutoff-insert-1-99mm","provider":"Voomi Supply","version":"1.0","type":"link"}
