It carries ISCAR grade IC807 with a PVD-applied TiAlN coating that delivers high wear resistance across a range of workpiece materials. The insert features a 35-degree diamond (rhombic) shape, a negative side clearance, and an NF chip breaker geometry optimized for finishing passes. Insert length is 0.49 inches (12.40 mm), inscribed circle is 0.28 inches (7.15 mm), and corner radius is 0.016 inches (1\/64 inch). It is part of the ISCAR Isoturn series and conforms to ISO 13399 standards.\u003c\/p\u003e\n\u003cp\u003eThis insert is suited for finishing-grade turning applications on steel, stainless steel, cast iron, and superalloys. The IC807 grade is rated for high to moderate wear resistance with adequate toughness, making it appropriate for shops running consistent finishing passes at controlled feed rates and depths of cut up to 2.00 mm (0.079 inches). Typical applications include external and internal diameter turning on medium to small parts. Licensed machinists and CNC operators in job shops, OEM production cells, and maintenance machining environments are the primary users of this insert style.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eIC807 grade with PVD TiAlN coating for high wear resistance on steel, stainless steel, cast iron, and superalloy workpieces\u003c\/li\u003e\n  \u003cli\u003e35-degree diamond (rhombic) insert shape provides a sharp, low-force cutting edge suited to finishing\u003c\/li\u003e\n  \u003cli\u003eNF chip breaker geometry designed specifically for finishing-pass chip control\u003c\/li\u003e\n  \u003cli\u003eNegative side clearance (N) with positive rake for stable clamping and consistent edge performance\u003c\/li\u003e\n  \u003cli\u003eConforms to ISO 13399 for standardized tooling data exchange and presetting\u003c\/li\u003e\n  \u003cli\u003eCompatible with clamp and pin holding methods for flexible toolholder use\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard VNMG-style replacement insert for Isoturn series toolholders accepting VNMG 2.5-1 (ISO: VNMG 12T304) inserts.

Disengage the machine spindle and verify the turret is fully indexed and locked before seating or removing inserts. Use the correct torx or clamp screw specified for the toolholder to secure the insert; do not overtighten, as carbide inserts are brittle and will crack under excess clamp force. Inspect the toolholder pocket and locating pin for wear or debris before seating a new insert to maintain edge repeatability.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eANSI Insert Code\u003c\/strong\u003e: VNMG2.5-1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eISO Insert Code\u003c\/strong\u003e: VNMG12T304\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Shape\u003c\/strong\u003e: V - Diamond (Rhombic) 35 degrees\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 (PVD process)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChip Breaker\u003c\/strong\u003e: NF (Finishing)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 9\/32 inches (0.2815 inches \/ 7.15 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Length\u003c\/strong\u003e: 0.4882 inches (12.40 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Thickness\u003c\/strong\u003e: 5\/32 inches (0.1560 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 1\/64 inches (0.0157 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Depth of Cut\u003c\/strong\u003e: 2.00 mm (0.0787 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHole Diameter\u003c\/strong\u003e: 0.1100 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRelief Angle\u003c\/strong\u003e: 0 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSide Clearance\u003c\/strong\u003e: Negative\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRake\u003c\/strong\u003e: Positive\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: Steel (P), Stainless Steel (M), Cast Iron (K), Superalloys (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\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: 5508221\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ISCAR","offers":[{"title":"Default Title","offer_id":51748970889522,"sku":"5508221","price":261.12,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/2cf9bb8f99d340a842e72f13c5e82bee.jpg?v=1788900710","url":"https:\/\/voomisupply.com\/products\/iscar-5508221-turning-insert-vnmg-ic807-tialn-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
