Identified by ANSI code CCGT 3-1-AS and ISO code CCGT09T304, this insert features an 80-degree diamond (rhombic) shape with a positive rake and positive side clearance geometry. The IC20 grade delivers high wear resistance while maintaining toughness, making it well suited for finishing passes on stainless steel, cast iron, and aluminum. The insert measures 0.3819 inches in length with a 3\/8-inch inscribed circle and a 1\/64-inch corner radius. It is held in place by a screw clamp and meets ISO 13399 standards. Machinists and CNC programmers select this grade when surface finish and dimensional accuracy are the priority.\u003c\/p\u003e\n\u003cp\u003eThis insert is intended for finishing-grade turning applications in general metalworking and precision machining environments. The AS chip breaker geometry is optimized for light, consistent cuts typical of finish-turning cycles. Primary workpiece materials include stainless steel (M), cast iron (K), and aluminum and non-ferrous materials (N). Secondary workpiece material codes include H and N. The insert is suited for both production and job-shop environments where tight tolerances and clean surface finishes are required at moderate to high cutting speeds.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eIC20 uncoated solid carbide grade with high wear resistance and toughness for stainless steel, cast iron, and non-ferrous materials\u003c\/li\u003e\n  \u003cli\u003e80-degree diamond (rhombic) insert shape with positive rake for reduced cutting forces during finishing operations\u003c\/li\u003e\n  \u003cli\u003eAS chip breaker designed for finishing-grade depth of cut up to 0.0984 inches (2.50 mm)\u003c\/li\u003e\n  \u003cli\u003e1\/64-inch corner radius for sharp, precise edge definition on finish passes\u003c\/li\u003e\n  \u003cli\u003eScrew-clamped insert holding method for secure, repeatable seating in compatible toolholders\u003c\/li\u003e\n  \u003cli\u003eMeets ISO 13399 tooling data standards for compatibility with modern CAM and tooling management systems\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in CCGT-style screw-clamp turning toolholders accepting a 3\/8-inch inscribed circle, 5\/32-inch thick insert with a 7-degree relief angle and positive rake geometry, per ANSI size code 3-1 and ISO size code 09T304.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by a qualified machinist or CNC tooling technician. Ensure the machine spindle is stopped and the turret or toolpost is indexed to a safe position before changing inserts. Use the appropriate Torx or hex key to seat the clamping screw to the toolholder manufacturer's specified torque. Inspect the insert pocket and clamping screw for wear or debris before seating a new insert, and verify the insert is fully seated and locked before resuming cutting operations.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eANSI Insert Code\u003c\/strong\u003e: CCGT 3-1-AS\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eISO Insert Code\u003c\/strong\u003e: CCGT09T304\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Shape\u003c\/strong\u003e: C - Diamond (Rhombic) 80 degrees\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: Bright \/ Uncoated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: Isoturn\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChip Breaker\u003c\/strong\u003e: AS (Finishing)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 3\/8 inch (0.3752 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Length\u003c\/strong\u003e: 0.3819 inches (9.70 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Thickness\u003c\/strong\u003e: 5\/32 inch (0.1563 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 1\/64 inch (0.0157 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHole Diameter\u003c\/strong\u003e: 0.1732 inches (4.40 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Depth of Cut\u003c\/strong\u003e: 0.0984 inches (2.50 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRelief Angle\u003c\/strong\u003e: 7 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eIncluded Angle\u003c\/strong\u003e: 80 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRake\u003c\/strong\u003e: Positive\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSide Clearance\u003c\/strong\u003e: Positive\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Holding Method\u003c\/strong\u003e: Screw\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Materials\u003c\/strong\u003e: P, M, K, N, S\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSecondary Workpiece Materials\u003c\/strong\u003e: H, N\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: C2, C3\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: ISO 13399\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.01 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: 5540004\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ISCAR","offers":[{"title":"Default Title","offer_id":51746885370162,"sku":"5540004","price":278.22,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/6dc6753ba7acee2117356309b5cc78d7.jpg?v=1788874331","url":"https:\/\/voomisupply.com\/products\/iscar-5540004-turning-insert-ccgt-3-1-as-ic20-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
