Carrying the GIPI478055P insert style designation within the Cut-Grip series, this insert features a 0.1882 inch (4.78 mm) cutting width and a double-end configuration, allowing both ends to be indexed for extended tool life. The uncoated IC20 carbide grade delivers consistent edge integrity across a broad range of workpiece materials. A positive rake angle of 8 degrees reduces cutting forces and supports smooth chip flow. The P chip breaker geometry manages chip control during grooving passes.\u003c\/p\u003e\n\u003cp\u003eThis insert is rated for universal primary workpiece material compatibility, covering ISO material groups H, K, M, N, and S. Typical applications include groove turning, parting off, and face grooving on small-to-medium diameter workpieces in production turning environments. The double-end design makes it well suited for high-volume operations where tooling cost per edge is a factor. Installation is performed using a clamp-style insert holding method, consistent with standard Cut-Grip toolholder bodies. Licensed machinists and CNC operators working in job shop or production environments are the primary users of this insert.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e0.1882 inch cutting width with matching 0.1882 inch overall width for accurate groove sizing\u003c\/li\u003e\n  \u003cli\u003eDouble-end insert — both ends are usable, lowering cost per cutting edge\u003c\/li\u003e\n  \u003cli\u003eUncoated IC20 solid carbide grade for consistent performance across universal material groups\u003c\/li\u003e\n  \u003cli\u003ePositive 8-degree rake angle reduces cutting forces and supports chip evacuation\u003c\/li\u003e\n  \u003cli\u003eP chip breaker geometry for controlled chip formation during grooving operations\u003c\/li\u003e\n  \u003cli\u003eClamp-style holding method for secure seating in compatible Cut-Grip toolholders\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with Cut-Grip series toolholders that accept the GIPI insert style.

Ensure the machine spindle is fully stopped and the program is in a safe state before changing or indexing inserts. Use the appropriate torx or hex key to seat the clamp fastener to the toolholder manufacturer specification. Inspect the insert pocket and clamp for debris or wear before seating the new insert.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: GIPI\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Size Code\u003c\/strong\u003e: 478055\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Width\u003c\/strong\u003e: 0.1882 inches (4.78 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 0.6181 inches (15.70 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Width\u003c\/strong\u003e: 0.1882 inches (4.78 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.0217 inches (0.55 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRake Angle\u003c\/strong\u003e: 8 degrees (Positive)\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\u003eChip Breaker\u003c\/strong\u003e: P\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: IC20\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Uncoated\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 (H, K, M, N, 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: 0.05 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: 6401389\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ISCAR","offers":[{"title":"Default Title","offer_id":51737894388018,"sku":"6401389","price":435.93,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/a1825324d86c1f0ca3f8dcb8ab2a4b6f.jpg?v=1788794908","url":"https:\/\/voomisupply.com\/products\/iscar-6401389-grooving-insert-0-1882-in-cut-grip","provider":"Voomi Supply","version":"1.0","type":"link"}
