Manufactured to the CNMP431-MF1-24 designation with manufacturer grade 890, this insert carries an 80-degree diamond shape, a 0.5-inch inscribed circle, and a 1\/64-inch (0.0157 inch) corner radius. The MF1 chip breaker geometry and honed cutting edge style make it particularly suited for finishing and semi-finishing passes. It is installed and used by machinists and CNC operators working with high-performance turning, boring, and facing operations.\u003c\/p\u003e\n\u003cp\u003eThis insert is engineered primarily for superalloys and titanium (ISO material code S), with secondary suitability for steel, cast iron, and non-ferrous materials (ISO codes M, K, N, H). Typical applications include external turning, facing, and boring operations on CNC lathes and turning centers where tight tolerances and consistent chip control are required. The negative rake geometry and neutral hand orientation support stable cutting across a wide range of workpiece configurations. The ISO equivalent designation is CNMG120404-MF1, and the insert meets both ANSI and ISO standards.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e80-degree diamond insert shape (shape code C) with negative rake for high edge strength\u003c\/li\u003e\n  \u003cli\u003eMF1 chip breaker geometry optimized for finishing cuts on superalloys and titanium\u003c\/li\u003e\n  \u003cli\u003eHoned cutting edge style for improved edge integrity and reduced chipping risk\u003c\/li\u003e\n  \u003cli\u003e4 cutting edges per insert for extended tool life and cost efficiency\u003c\/li\u003e\n  \u003cli\u003eCompatible with clamp, pin, and lever lock insert holding methods\u003c\/li\u003e\n  \u003cli\u003eMeets ANSI and ISO standards; ISO equivalent CNMG120404-MF1\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in CNMP-style toolholders that accept a 0.5-inch inscribed circle, 3\/16-inch thick, 80-degree diamond insert with neutral hand orientation.

Ensure the toolholder pocket is clean and free of chips or debris before seating the insert. Follow the toolholder manufacturer's clamping torque guidelines for the specific clamp, pin, or lever lock system in use. Inspect the cutting edge for damage before each use and index or replace the insert when wear is detected to maintain workpiece tolerance.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: CNMP\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: CNMP-MF1\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\u003eInsert Shape\u003c\/strong\u003e: Diamond 80 degrees\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\u003eCorner Radius\u003c\/strong\u003e: 1\/64 inch (0.0157 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Thickness\u003c\/strong\u003e: 3\/16 inch (0.1874 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Length\u003c\/strong\u003e: 0.5079 inches\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\u003eNumber of Cutting Edges\u003c\/strong\u003e: 4\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: Honed\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\u003eRelief Angle\u003c\/strong\u003e: 0 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTolerance Code\u003c\/strong\u003e: M\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eClearance Code\u003c\/strong\u003e: N\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\u003eApplication\u003c\/strong\u003e: Boring, Facing, Turning\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eISO Equivalent\u003c\/strong\u003e: CNMG120404-MF1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: ANSI, ISO\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Order Quantity\u003c\/strong\u003e: 10\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\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: SECO\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 74050197\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SECO TOOLS","offers":[{"title":"Default Title","offer_id":51562595418418,"sku":"74050197","price":191.79,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/ae6bed6a4218bad034358755aa462144_cd54cb1f-b82f-4b62-b42a-0751a9d989bc.jpg?v=1786480423","url":"https:\/\/voomisupply.com\/products\/seco-74050197-turning-insert-cnmp431-mf1-24-890-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
