Identified by grade IC8250 with a CVD-applied Al2O3 coating, this insert delivers thermal resistance and wear performance suited to interrupted and continuous grooving cuts. It carries a 6.35 mm (0.25 inches) cutting width and a maximum depth of cut of 10.64 mm (0.419 inches). The positive rake angle of 7 degrees and P chip breaker geometry work together to control chip evacuation in demanding turning applications. Machinists and CNC operators in production and job-shop environments install this insert type.\u003c\/p\u003e\u003cp\u003eThis insert is intended for grooving stainless steel and steel workpieces, corresponding to ISO material groups M and P. It fits applications where consistent groove width, controlled chip flow, and reliable tool life are required across moderate to deep grooving depths ranging from 10.00 mm to 20.00 mm (0.300 inches to 1.000 inches). The self-grip holding method locks the insert securely in compatible Cut-Grip toolholders without additional clamping hardware. It is suited for both production runs and precision finishing passes where groove geometry must be held to close tolerance.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eIC8250 grade CVD Al2O3 coating for thermal barrier and extended wear resistance in steel and stainless steel grooving\u003c\/li\u003e\n\u003cli\u003e6.35 mm (0.25 inches) cutting width with a corner radius of 3.18 mm (1\/8 inches) for consistent groove profile\u003c\/li\u003e\n\u003cli\u003eMaximum depth of cut of 10.64 mm (0.419 inches) within a working range of 10.00 mm to 20.00 mm\u003c\/li\u003e\n\u003cli\u003ePositive rake angle of 7 degrees with P chip breaker geometry for controlled chip formation\u003c\/li\u003e\n\u003cli\u003eSelf-grip insert holding method eliminates the need for separate clamping screws\u003c\/li\u003e\n\u003cli\u003eNeutral hand orientation allows use in standard straight-grooving setups\u003c\/li\u003e\n\u003cli\u003eConforms to ISO 13399 tooling data standards for compatibility with CAM and tool management systems\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in ISCAR Cut-Grip series toolholders that accept GIP-style inserts with size code 635E318.

Power down and lock out the machine spindle before seating or removing any insert. Ensure the toolholder pocket is clean and free of chips or debris before installing the insert, as contamination can affect seating and cause premature edge failure. Do not exceed the maximum depth of cut rating for the insert grade and workpiece material combination.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: GIP\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Size Code\u003c\/strong\u003e: 635E318\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Width\u003c\/strong\u003e: 6.35 mm (0.25 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Depth of Cut\u003c\/strong\u003e: 10.64 mm (0.419 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDepth of Cut Range\u003c\/strong\u003e: 10.00 mm to 20.00 mm (0.300 inches to 1.000 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Height\u003c\/strong\u003e: 5.00 mm (0.197 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 0.602 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 3.18 mm (1\/8 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRake Angle\u003c\/strong\u003e: 7 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Hand\u003c\/strong\u003e: Neutral\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: IC8250\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Al2O3 (CVD)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChip Breaker\u003c\/strong\u003e: P\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Holding Method\u003c\/strong\u003e: Self Grip\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Stainless Steel, Steel (ISO M, P)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: Cut-Grip\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eISO Code\u003c\/strong\u003e: GIP 6.35E-3.18\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: 10\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: 6404320\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ISCAR","offers":[{"title":"Default Title","offer_id":51750896992562,"sku":"6404320","price":718.27,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/dd185fa0560cb5c4ac1223477f915490.jpg?v=1788920427","url":"https:\/\/voomisupply.com\/products\/iscar-6404320-grooving-insert-ic8250-0-25-in-cut-width","provider":"Voomi Supply","version":"1.0","type":"link"}
