The insert features a Physical Vapor Deposition (PVD) TiAlN coating applied over a submicron carbide substrate, delivering wear resistance and heat stability at elevated cutting speeds. Key geometry details include a 55-degree diamond shape, a 3\/8-inch inscribed circle, a 1\/64-inch corner radius, and a positive rake configuration with an NF chip breaker. This insert is installed and changed out by machinists and CNC setup technicians in production and job shop environments.\u003c\/p\u003e\u003cp\u003eThe DNMG331NF IC807 insert is suited for turning applications on stainless steel (ISO M), carbon and alloy steels (ISO P), and superalloys and high-temperature alloys (ISO S). It performs in both continuous and light interrupted cuts where a positive-rake insert with a fine chip breaker and TiAlN coating provides an advantage. The NF chip breaker geometry supports controlled chip formation at light to medium depths of cut, making this insert a practical choice for finishing and semi-finishing passes on precision turned components.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003ePVD TiAlN coating over submicron solid carbide substrate for extended tool life in steel and stainless applications\u003c\/li\u003e\n\u003cli\u003e55-degree diamond (DNMG) insert shape with positive rake for reduced cutting forces\u003c\/li\u003e\n\u003cli\u003eNF chip breaker geometry optimized for light to medium depth finishing and semi-finishing cuts\u003c\/li\u003e\n\u003cli\u003eMaximum depth of cut of 0.118 inches (3.00 mm)\u003c\/li\u003e\n\u003cli\u003eClamp and pin holding method for secure, repeatable seating in compatible toolholders\u003c\/li\u003e\n\u003cli\u003eConforms to ISO 13399 tooling data standards for integration with CAM and tool management systems\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in DNMG-style turning toolholders that accept a 3\/8-inch inscribed circle insert with a 0.150-inch hole diameter and clamp-plus-pin holding.

The machine spindle must be stopped and the turret or tool post fully de-energized before indexing or replacing inserts. Use the appropriate clamp screw torque driver recommended for DNMG-style toolholders to avoid cracking the carbide or stripping the clamp. Inspect the toolholder pocket for chips or debris before seating the insert to ensure proper contact and repeatability.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: DNMG\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Shape\u003c\/strong\u003e: Diamond 55 Degree\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: IC807\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 Material\u003c\/strong\u003e: Solid Carbide (Submicron)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChip Breaker\u003c\/strong\u003e: NF\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRake\u003c\/strong\u003e: Positive\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 3\/8 inches (0.375 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 1\/64 inches (0.0156 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Length\u003c\/strong\u003e: 0.458 inches (11.63 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Thickness\u003c\/strong\u003e: 3\/16 inches (0.1875 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHole Diameter\u003c\/strong\u003e: 0.150 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Depth of Cut\u003c\/strong\u003e: 0.118 inches (3.00 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 Materials\u003c\/strong\u003e: ISO M, ISO P, ISO S\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: Isoturn\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: 0.176 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: 5550314\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ISCAR","offers":[{"title":"Default Title","offer_id":51735616291122,"sku":"5550314","price":241.5,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/37d4ba990d94e53186cd682a52f202df.jpg?v=1788773268","url":"https:\/\/voomisupply.com\/products\/iscar-5550314-dnmg331nf-ic807-turning-insert-diamond-55","provider":"Voomi Supply","version":"1.0","type":"link"}
