Manufactured from solid carbide and coated with TiCN and Al2O3 via a CVD process, this insert delivers wear resistance and thermal stability during continuous and interrupted cutting. The 80-degree diamond shape provides a sturdy cutting edge with a 0.0625-inch corner radius. With an inscribed circle of 0.75 inches and an insert length of 19.3 mm (0.76 inches), it fits standard CNMG toolholders. Machining professionals in production and job-shop environments rely on this grade for demanding turning cycles.\u003c\/p\u003e\n\u003cp\u003eThis insert is rated for primary workpiece materials including cast iron (ISO material group K) and steel (ISO material group P), making it suitable for a wide range of turning applications in automotive, general manufacturing, and heavy machining environments. The NR chip breaker geometry controls chip flow effectively across moderate to aggressive depths of cut, up to a maximum depth of cut of 10.0 mm (0.3937 inches). It is intended for use by machinists and CNC operators requiring consistent tool life and surface finish on ferrous workpieces.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide substrate with CVD-applied TiCN and Al2O3 dual-layer coating for extended wear resistance\u003c\/li\u003e\n  \u003cli\u003e80-degree diamond insert shape (CNMG) with 0.0625-inch corner radius for strong edge geometry\u003c\/li\u003e\n  \u003cli\u003eNR chip breaker optimized for cast iron and steel turning applications\u003c\/li\u003e\n  \u003cli\u003eMaximum depth of cut of 10.0 mm (0.3937 inches) for versatile stock removal\u003c\/li\u003e\n  \u003cli\u003eClamp and pin insert holding method for secure seating in compatible toolholders\u003c\/li\u003e\n  \u003cli\u003eConforms to ISO 13399 tooling data standards for system integration\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement turning insert for CNMG-style toolholders used in external turning operations on steel and cast iron workpieces within the Isoturn series.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified machinist or CNC operator with the machine fully powered down and the spindle locked before insert exchange. Use the appropriate torque wrench and clamp hardware specified by the toolholder manufacturer to secure the insert without over-tightening. Inspect the insert pocket and seating surface for chips or wear before installing a new insert. Follow your facility safety procedures and machine tool manufacturer guidelines during all tooling changes.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: CNMG\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Shape\u003c\/strong\u003e: Diamond (80 degree included angle)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: Isoturn\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: IC8150\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: TiCN and Al2O3\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating Process\u003c\/strong\u003e: CVD\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 Length\u003c\/strong\u003e: 19.3 mm (0.76 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: 1\/16 inches (0.0625 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Depth of Cut\u003c\/strong\u003e: 10.0 mm (0.3937 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChip Breaker\u003c\/strong\u003e: NR\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: Cast Iron, Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandard\u003c\/strong\u003e: ISO 13399\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Weight\u003c\/strong\u003e: 0.661 pounds\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\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: 5507838\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ISCAR","offers":[{"title":"Default Title","offer_id":51730659410226,"sku":"5507838","price":528.05,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/851764b54863da31d14237601d3d7c5f_d149a864-9135-4cb4-9fdf-742193f91094.jpg?v=1788721011","url":"https:\/\/voomisupply.com\/products\/iscar-5507838-cnmg644nr-ic8150-turning-insert-3-4-in-ic","provider":"Voomi Supply","version":"1.0","type":"link"}
