Manufactured to ANSI code CNGG330.5 and ISO code CNGG090402ML K10, this insert features an 80-degree diamond (rhombic) shape with a negative rake and negative side clearance. The uncoated K10 carbide grade delivers high wear-resistance when cutting cast iron, superalloys, titanium, and non-ferrous metals. With four usable cutting edges and a clamp-style holding method, it provides consistent performance across roughing and medium machining operations.\u003c\/p\u003e\u003cp\u003eThis insert is suited for turning applications on cast iron components, titanium parts, superalloys, and non-ferrous workpieces in both production and job-shop environments. The ML chip breaker geometry is optimized for roughing and medium machining passes where chip control and edge integrity are critical. Machinists and tooling specialists working in aerospace, automotive, and general machining will find this insert compatible with standard CNGG-series toolholders. It is sold individually.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eK10 uncoated carbide grade  -  high wear-resistance for cast iron, superalloys, titanium, and non-ferrous metals\u003c\/li\u003e\n\u003cli\u003e80-degree diamond insert shape (CNGG) with negative rake for stable, rigid cutting action\u003c\/li\u003e\n\u003cli\u003eML chip breaker geometry supports roughing and medium machining operations\u003c\/li\u003e\n\u003cli\u003eFour cutting edges per insert for extended tooling value\u003c\/li\u003e\n\u003cli\u003e0.0080-inch corner radius for controlled edge geometry\u003c\/li\u003e\n\u003cli\u003eClamp-style holding method compatible with standard CNGG toolholders\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or standard drop-in for CNGG-series turning toolholders accepting ANSI size code 330.5 inserts with a clamp-style holding method.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eTurning insert installation should be performed by a qualified machinist or tooling technician with the machine powered down and in a locked-out state. Ensure the toolholder pocket and clamp are clean and free of debris before seating the insert. Use the appropriate torx or clamp screw torque per the toolholder manufacturer specification  -  do not over-tighten, as this can fracture the carbide. Verify insert seating and edge orientation before resuming cutting operations.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eANSI Insert Code\u003c\/strong\u003e: CNGG330.5\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eISO Insert Code\u003c\/strong\u003e: CNGG090402ML K10\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: K10\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: Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Hand\u003c\/strong\u003e: Neutral\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 0.3750 inches (3\/8 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Length\u003c\/strong\u003e: 0.3820 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Thickness\u003c\/strong\u003e: 0.1870 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.0080 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Depth of Cut\u003c\/strong\u003e: 0.0470 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Cutting Edges\u003c\/strong\u003e: 4\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChip Breaker\u003c\/strong\u003e: ML\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChip Breaker Operation\u003c\/strong\u003e: Roughing and Medium Machining\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRake\u003c\/strong\u003e: Negative\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSide Clearance\u003c\/strong\u003e: Negative\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRelief Angle\u003c\/strong\u003e: 0 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIncluded Angle\u003c\/strong\u003e: 80 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Holding Method\u003c\/strong\u003e: Clamp\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Materials\u003c\/strong\u003e: Cast Iron, Superalloy, Titanium, Non-Ferrous Metal\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: CNGG\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.01 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23242105\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: INGERSOLL CUTTING TOOLS\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 6139412\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"INGERSOLL CUTTING TOOLS","offers":[{"title":"Default Title","offer_id":51972011262258,"sku":"6139412","price":27.84,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/9991128bf361830bf07825440008daac_388de0f9-654b-426d-b1fc-baab9d692ad8.jpg?v=1789960902","url":"https:\/\/voomisupply.com\/products\/ingersoll-cutting-tools-6139412-turning-insert-cngg330-5","provider":"Voomi Supply","version":"1.0","type":"link"}
