It carries the GEPI318159 insert style designation and is manufactured in IC908 grade with a PVD-applied TiAlN coating. Cutting width is 3.18 mm (0.1252 inches), with a maximum depth of cut of 5 mm (0.1969 inches). The double-ended geometry and positive rake angle of 8 degrees allow productive cutting in both directions, and the full corner radius of 1.59 mm (0.0626 inches) supports smooth finishing passes. Licensed machinists and CNC turning specialists install this insert into compatible Cut-Grip toolholders.\u003c\/p\u003e\n\u003cp\u003eThis insert is suited for universal workpiece materials spanning ISO material groups H, K, M, P, and S — covering hardened steels, cast irons, stainless steels, general steels, and heat-resistant superalloys. It is commonly used in production turning shops for groove profiling and cutoff work on both ferrous and non-ferrous components. The clamp-held, double-ended design extends service life by offering two cutting edges per insert. The IC908 submicron carbide grade with TiAlN finish performs reliably across a broad range of cutting speeds and chip loads typical in general-purpose turning.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eIC908 submicron carbide grade with PVD TiAlN coating for wear resistance across universal workpiece materials\u003c\/li\u003e\n  \u003cli\u003eDouble-ended insert design provides two usable cutting edges per insert\u003c\/li\u003e\n  \u003cli\u003e3.18 mm cutting width with full corner radius of 1.59 mm for consistent groove geometry\u003c\/li\u003e\n  \u003cli\u003ePositive rake angle of 8 degrees reduces cutting forces and supports smooth chip flow\u003c\/li\u003e\n  \u003cli\u003eClamp-held insert holding method for secure, repeatable seating in Cut-Grip toolholders\u003c\/li\u003e\n  \u003cli\u003eCompliant with ISO 13399 cutting tool data standards for compatible CAM and tooling systems\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in ISCAR Cut-Grip series toolholders that accept GEPI-style inserts with a 318159 size code.

Power down and lock out the machine before changing inserts. Seat the insert fully against the toolholder pocket and tighten the clamping screw to the toolholder manufacturer's specified torque — do not exceed that value or overtorque by feel. Inspect the insert seat and clamping components for chips or debris before each insert change to ensure accurate positioning and tool life.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: GEPI318159\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: IC908\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Width\u003c\/strong\u003e: 3.18 mm (0.1252 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Depth of Cut\u003c\/strong\u003e: 5.00 mm (0.1969 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFull Corner Radius\u003c\/strong\u003e: 1.59 mm (0.0626 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 10.00 mm (0.3937 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Width\u003c\/strong\u003e: 3.18 mm (0.1252 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRake Angle\u003c\/strong\u003e: 8 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Hand\u003c\/strong\u003e: Neutral\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSingle or Double End\u003c\/strong\u003e: Double\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: Submicron\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\u003eInsert Holding Method\u003c\/strong\u003e: Clamp\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\u003eSeries\u003c\/strong\u003e: Cut-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: 0.002 pounds\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: 6403376\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ISCAR","offers":[{"title":"Default Title","offer_id":51753413181746,"sku":"6403376","price":498.46,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/08dd875c44f243c8ba795e13e975aefa.jpg?v=1788936548","url":"https:\/\/voomisupply.com\/products\/iscar-6403376-grooving-insert-gepi318159-ic908-tialn","provider":"Voomi Supply","version":"1.0","type":"link"}
