Manufactured to the GIM3-8RA geometry in ISCAR grade IC908, it features a TiAlN PVD coating that provides high wear resistance and thermal stability across a broad range of workpiece materials. The insert has a right-hand cutting orientation, a 0.1181 inch cutting width, and a positive rake angle of 7 degrees. An 8-degree lead angle and submicron carbide substrate combine to deliver consistent edge integrity at elevated cutting speeds. This insert is installed by machinists and CNC operators working in production turning environments.\u003c\/p\u003e\u003cp\u003eThis insert is suited for grooving operations on materials classified under universal workpiece categories, including steels, stainless steels, cast irons, high-temperature alloys, and hardened materials corresponding to material codes H, K, M, P, and S. It fits into the Cut-Grip clamping system, which uses a clamp and screw holding method to secure the insert in compatible ISCAR Cut-Grip toolholders. The W chip breaker geometry supports effective chip control across a range of depths of cut and feed rates typical in production turning.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eIC908 grade with TiAlN PVD coating for wear resistance on universal workpiece materials\u003c\/li\u003e\n\u003cli\u003e0.1181 inch cutting width with 0.0098 inch corner radius for precise groove geometry\u003c\/li\u003e\n\u003cli\u003ePositive rake angle of 7 degrees reduces cutting forces and supports sharp, stable edges\u003c\/li\u003e\n\u003cli\u003e8-degree lead angle for smooth entry and reduced insert loading\u003c\/li\u003e\n\u003cli\u003eW chip breaker geometry promotes reliable chip evacuation during grooving\u003c\/li\u003e\n\u003cli\u003eSubmicron carbide substrate enhances toughness and edge consistency at elevated speeds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with ISCAR Cut-Grip series toolholders that accept the GIM insert style in size code 38 with a clamp and screw holding method.

Use the appropriate ISCAR torx or hex key to secure the clamping screw to the toolholder manufacturer's specified procedure. Inspect the insert pocket and clamping surfaces for chips or debris before seating the insert. Never operate the insert in a toolholder not designed for the Cut-Grip system, as improper seating can cause insert failure or workpiece damage.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: GIM\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\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\u003eCutting Width\u003c\/strong\u003e: 0.1181 inches (3.00 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 0.6024 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Width\u003c\/strong\u003e: 0.1181 inches (3.00 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.0098 inches (0.25 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Hand\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRake\u003c\/strong\u003e: Positive\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRake Angle\u003c\/strong\u003e: 7 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLead Angle\u003c\/strong\u003e: 8 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChip Breaker\u003c\/strong\u003e: W\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Holding Method\u003c\/strong\u003e: Clamp and Screw\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: Cut-Grip\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Universal (H, K, M, P, S)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFull Radius\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eANSI Code\u003c\/strong\u003e: GIM 3-8RA IC908\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandards\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: 6403170\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ISCAR","offers":[{"title":"Default Title","offer_id":51753811509554,"sku":"6403170","price":233.26,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/6bda6bbe1901a1dc167736e88cfce928.jpg?v=1788940914","url":"https:\/\/voomisupply.com\/products\/iscar-6403170-grooving-insert-gim3-8ra-ic908-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
