It carries the ISO designation 3-80-101104-8-L4 4415 and features a multilayer CVD coating system consisting of TiCN, Al2O3, and TiN for extended wear resistance and thermal protection at the cutting edge. The insert is neutral hand, making it suitable for use in both left- and right-hand toolholders. A corner radius of 0.0156 inches contributes to surface finish control and edge stability during turning passes. Grade 4415 is a coated carbide grade suited to continuous and light interrupted steel cutting applications. The L4 chip breaker geometry assists with chip control across a range of depths of cut and feed rates.\u003c\/p\u003e\u003cp\u003eThis insert is intended for lathe and turning center applications where steel is the primary workpiece material. The secondary workpiece material code K indicates suitability for cast iron as well. The 3-80-L4 series is commonly used in external and facing operations on CNC turning equipment. It is installed and serviced by machinists and CNC lathe operators in production and job shop environments. The clamp and screw holding method accommodates standard toolholders designed for this insert style. This insert ships individually but carries a minimum order quantity of 2 units.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eMultilayer CVD coating: TiCN plus Al2O3 plus TiN for heat and wear resistance\u003c\/li\u003e\n\u003cli\u003eGrade 4415 coated carbide optimized for steel turning\u003c\/li\u003e\n\u003cli\u003eNeutral hand geometry compatible with left- and right-hand holders\u003c\/li\u003e\n\u003cli\u003eL4 chip breaker for effective chip control during steel cutting\u003c\/li\u003e\n\u003cli\u003e0.0156-inch corner radius for surface finish and edge stability\u003c\/li\u003e\n\u003cli\u003eCompatible with clamp and screw holding methods\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement turning insert for toolholders and turning centers accepting 3-80 series inserts with clamp or screw holding in the 3-80-L4 series.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eTurning insert replacement should be performed by a qualified machinist or CNC operator with the machine spindle stopped and all axes at a safe position. Use the appropriate torque wrench and insert key for the clamp or clamping screw to avoid over-tightening and seat damage. Inspect the insert pocket and shim for wear or debris before seating the new insert. Follow shop safety procedures and machine manufacturer guidelines when handling carbide inserts, as edges are extremely sharp.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eISO Code\u003c\/strong\u003e: 3-80-101104-8-L4 4415\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: 4415\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, Al2O3, TiN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating Process\u003c\/strong\u003e: CVD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: 3-80\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 3-80-L4\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChip Breaker\u003c\/strong\u003e: L4\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Hand\u003c\/strong\u003e: Neutral\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.0156 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Thickness\u003c\/strong\u003e: 0.4331 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 0.3937 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRelief Angle\u003c\/strong\u003e: 0 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSecondary Workpiece Material Code\u003c\/strong\u003e: K\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Holding Method\u003c\/strong\u003e: Clamp, Screw\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: 2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.08 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23171618\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: SANDVIK COROMANT\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 7859290\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SANDVIK COROMANT","offers":[{"title":"Default Title","offer_id":51755671552306,"sku":"7859290","price":122.87,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/6b86591be4645b7d78b70bcc1ada58e6.jpg?v=1788957883","url":"https:\/\/voomisupply.com\/products\/sandvik-coromant-7859290-turning-insert-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
