The insert carries an IC807 manufacturer grade with a PVD-applied TiAlN coating, which supports higher cutting speeds and improved wear resistance in interrupted and continuous cuts. Key geometry specs include a 3\/4-inch inscribed circle, a 1\/4-inch insert thickness, a 3\/64-inch corner radius, a 90-degree square insert shape, and a maximum depth of cut of 0.315 inches. It is held by clamp and pin and features an NR chip breaker designation. Licensed machinists and CNC operators install this insert during tooling setup or insert rotation cycles.\u003c\/p\u003e\n\u003cp\u003eThis insert is suited for turning operations on a range of workpiece materials including steels (P), stainless steels (M), and superalloys (S), as indicated by the primary workpiece material codes P, M, and S. The Isoturn series is commonly applied in both roughing and semi-finishing passes in production shop environments. The SNMG643 ISO geometry and NR chip breaker combination make it a practical choice for general-purpose turning where controlled chip formation and consistent tool life are priorities. It conforms to ISO 13399 standards for cutting tool data representation.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eIC807 grade PVD TiAlN coating for improved wear resistance and higher cutting speeds\u003c\/li\u003e\n  \u003cli\u003e90-degree square insert shape (SNMG) with 0-degree relief angle and NR chip breaker\u003c\/li\u003e\n  \u003cli\u003e3\/4-inch inscribed circle and 3\/64-inch corner radius for defined cutting geometry\u003c\/li\u003e\n  \u003cli\u003eMaximum depth of cut of 0.315 inches suitable for roughing and semi-finishing passes\u003c\/li\u003e\n  \u003cli\u003eClamp and pin holding method for secure seating in compatible toolholders\u003c\/li\u003e\n  \u003cli\u003eConforms to ISO 13399 cutting tool data standards\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in SNMG-style insert toolholders that accept a 3\/4-inch inscribed circle, 1\/4-inch thick square insert with a 0.313-inch hole diameter.

Ensure the toolholder pocket and clamping surfaces are clean and free of chips before seating the insert. Use the correct torque driver for the clamp screw as specified by the toolholder manufacturer. Do not exceed the maximum depth of cut rating for the insert grade and workpiece material combination in use.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: SNMG\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eISO Code\u003c\/strong\u003e: SNMG643\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: IC807\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Material\u003c\/strong\u003e: Solid Carbide (Submicron)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\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 Shape\u003c\/strong\u003e: Square (90 degrees)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChip Breaker\u003c\/strong\u003e: NR\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 3\/4 inches (0.7500 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Thickness\u003c\/strong\u003e: 1\/4 inches (0.2500 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 3\/64 inches (0.0469 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHole Diameter\u003c\/strong\u003e: 0.313 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Depth of Cut\u003c\/strong\u003e: 0.315 inches (8.00 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 0.7500 inches (19.05 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRelief Angle\u003c\/strong\u003e: 0 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eClearance Code\u003c\/strong\u003e: N\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTolerance Code\u003c\/strong\u003e: M\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Holding Method\u003c\/strong\u003e: Clamp and Pin\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: M, P, S\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: Isoturn\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: ISO 13399\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1 insert per package\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: 0.683 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: 5550427\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ISCAR","offers":[{"title":"Default Title","offer_id":51750637109554,"sku":"5550427","price":429.9,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/30c76afeadf40db1563fe48e2d6cf19f.jpg?v=1788917615","url":"https:\/\/voomisupply.com\/products\/iscar-5550427-snmg643nr-ic807-turning-insert-3-4-in-ic","provider":"Voomi Supply","version":"1.0","type":"link"}
