It features an 80-degree diamond (C-shape) insert geometry with a negative rake angle and a sharp cutting edge style. The inscribed circle measures 0.5 inches, insert thickness is 0.1874 inches, and insert length is 0.5079 inches. With an uncoated (bright) finish and the MF1 chip breaker geometry, this insert is engineered for precision metal removal in demanding machining operations. It is compatible with clamp, pin, and lever lock holding methods. Each order ships in single-piece packaging with a minimum order quantity of 10 pieces.\u003c\/p\u003e\u003cp\u003eThis insert is designed for boring, facing, and turning operations with a primary focus on superalloys and titanium workpiece materials (ISO material code S). Secondary material compatibility includes steel (M), cast iron (K), non-ferrous metals (N), and hardened materials (H). The MF1 chip breaker geometry supports light to medium finishing cuts where controlled chip formation is critical. Typical applications include aerospace component machining and other high-performance turning environments where tool life and edge consistency are essential. The neutral hand orientation allows flexible use across a range of toolholder configurations.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide construction, uncoated (bright finish) for consistent edge performance on superalloys and titanium\u003c\/li\u003e\n\u003cli\u003e80-degree diamond insert shape (C) with negative rake and sharp cutting edge style\u003c\/li\u003e\n\u003cli\u003eMF1 chip breaker geometry optimized for light to medium finishing passes\u003c\/li\u003e\n\u003cli\u003eFour cutting edges available per insert, reducing cost per edge\u003c\/li\u003e\n\u003cli\u003eCompatible with clamp, pin, and lever lock holding methods for versatile toolholder fitment\u003c\/li\u003e\n\u003cli\u003eConforms to ANSI and ISO standards; ISO equivalent code CNGG120404-MF1\u003c\/li\u003e\n\u003cli\u003eMulti-use application: boring, facing, and turning in a single insert designation\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in CNGP-series toolholders that accept a 0.5-inch inscribed circle, 80-degree diamond insert with clamp, pin, or lever lock holding.

Seat the insert fully against all pocket walls and torque the clamp or locking screw according to the toolholder manufacturer's specifications. Inspect the insert pocket and seating surface for chips or debris before seating a new insert, as foreign material will cause premature edge failure or pocket damage. Dispose of worn inserts properly, as carbide edges remain sharp and pose a laceration hazard.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: CNGP\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIndustry Standard Number\u003c\/strong\u003e: CNGP431F-MF1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eISO Code\u003c\/strong\u003e: CNGG120404-MF1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Shape\u003c\/strong\u003e: Diamond 80 (C)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIncluded Angle\u003c\/strong\u003e: 80 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: 890\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: S10, S20\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating \/ Finish\u003c\/strong\u003e: Uncoated (Bright)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChip Breaker\u003c\/strong\u003e: MF1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Edge Style\u003c\/strong\u003e: Sharp\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRake\u003c\/strong\u003e: Negative\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: 0.5 inches (12.70 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Length\u003c\/strong\u003e: 0.5079 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Thickness\u003c\/strong\u003e: 0.1874 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.0157 inches (1\/64 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHole Diameter\u003c\/strong\u003e: 0.2028 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Depth of Cut\u003c\/strong\u003e: 0.4921 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRelief Angle\u003c\/strong\u003e: 0 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eClearance Code\u003c\/strong\u003e: N\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTolerance Code\u003c\/strong\u003e: G\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Cutting Edges\u003c\/strong\u003e: 4\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Holding Method\u003c\/strong\u003e: Clamp, Pin, Lever Lock\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Superalloys and Titanium (Code S)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSecondary Workpiece Material Codes\u003c\/strong\u003e: M, K, N, H\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMulti-Use Application\u003c\/strong\u003e: Boring, Facing, Turning\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: CNGP-MF1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: ANSI, ISO\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1 piece per package\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMinimum Order Quantity\u003c\/strong\u003e: 10 pieces\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: SECO\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 74030811\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SECO TOOLS","offers":[{"title":"Default Title","offer_id":51563875926322,"sku":"74030811","price":340.43,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/2359d5aa8792a5c59b41883710122445.jpg?v=1786505688","url":"https:\/\/voomisupply.com\/products\/seco-74030811-cngp431f-mf1-24-turning-insert-890-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
