It features an 80-degree diamond insert shape with a 3\/8-inch (0.3750-inch decimal) inscribed circle and a minimal corner radius of 0.0039 inches, making it well suited for light finishing cuts where surface finish and dimensional accuracy are critical. The insert is coated via a PVD process in SUMITOMO T1500Z grade cermet, which provides wear resistance and thermal stability at elevated cutting speeds. A screw-holding method and positive rake geometry contribute to consistent seating and chip control. This insert is installed by CNC machinists and tool and die professionals working on steel turning operations.\u003c\/p\u003e\u003cp\u003eThis insert is intended for finish turning applications on steel materials, classified under ISO workpiece material code P. The MESI chip breaker geometry is engineered to manage chip flow during light to medium depth-of-cut passes, reducing the risk of chip buildup on the workpiece or cutting tool. It is appropriate for use in CNC lathes and turning centers where tight tolerances and fine surface finishes are required. The ISO code equivalent is CCGT09T301MN-SI. The ANSI and ISO 13399 standards apply to this insert geometry.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eCCGT insert style with 80-degree diamond shape for stable finish-turning geometry\u003c\/li\u003e\n\u003cli\u003eT1500Z grade cermet with PVD coating for wear resistance on steel workpieces\u003c\/li\u003e\n\u003cli\u003eMESI chip breaker for controlled chip evacuation during finish cuts\u003c\/li\u003e\n\u003cli\u003ePositive rake angle reduces cutting forces on light finishing passes\u003c\/li\u003e\n\u003cli\u003eScrew-holding method ensures secure insert clamping and repeatable positioning\u003c\/li\u003e\n\u003cli\u003eMeets ANSI and ISO 13399 insert geometry standards\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or direct-fit insert for CCGT-style turning toolholders accepting a 3\/8-inch inscribed circle, 5\/32-inch thickness insert with a screw-holding method and clearance code C, tolerance code G.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThis insert is installed by qualified machinists or CNC tooling technicians. Power down and lock out the machine spindle before changing inserts. Use the appropriate torx or hex key as specified by the toolholder manufacturer to secure the clamping screw to the correct seating torque per the toolholder documentation. Inspect the insert pocket and seating surfaces for chips or debris before seating the new insert to ensure proper contact and runout.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: CCGT\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\u003eInsert Shape Code\u003c\/strong\u003e: C\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInscribed Circle (Inch)\u003c\/strong\u003e: 3\/8 inch (0.3750 inches decimal)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius (Decimal Inch)\u003c\/strong\u003e: 0.0039 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Thickness (Inch)\u003c\/strong\u003e: 5\/32 inch (0.1563 inches decimal)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Length (Decimal Inch)\u003c\/strong\u003e: 0.1398 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHole Diameter (Decimal Inch)\u003c\/strong\u003e: 0.1732 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRelief Angle\u003c\/strong\u003e: 7 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRake\u003c\/strong\u003e: Positive\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Hand\u003c\/strong\u003e: Neutral\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Material\u003c\/strong\u003e: Cermet\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: T1500Z\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Coated (PVD)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChip Breaker\u003c\/strong\u003e: MESI\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Holding Method\u003c\/strong\u003e: Screw\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eClearance Code\u003c\/strong\u003e: C\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTolerance Code\u003c\/strong\u003e: G\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Steel (ISO Code P)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eISO Code\u003c\/strong\u003e: CCGT09T301MN-SI\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: CC\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: ANSI; ISO 13399\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23242105\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Dimensions\u003c\/strong\u003e: 0.38 x 0.38 x 0.16 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.015 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMinimum Order Quantity\u003c\/strong\u003e: 10\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: SUMITOMO\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 1N4A005\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SUMITOMO","offers":[{"title":"Default Title","offer_id":51755667390770,"sku":"1N4A005","price":185.45,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/97d99804c41492d54fe2303a7eaa3869.jpg?v=1788957830","url":"https:\/\/voomisupply.com\/products\/sumitomo-1n4a005-cermet-turning-insert-ccgt-3-8-inch-ic","provider":"Voomi Supply","version":"1.0","type":"link"}
