Built to ANSI code CNMG432 and ISO code CNMG120408, this insert features a CVD coating and a diamond (rhombic) 80-degree insert shape that delivers high wear resistance across steel and cast iron workpiece materials. The 0.80 mm corner radius and negative side clearance geometry support stable, controlled cuts. With four usable cutting edges per insert, it reduces tooling cost per edge in high-volume production environments. Grade ACK20P with a WM+ chip breaker rounds out the specification for consistent chip control in general turning applications.\u003c\/p\u003e\u003cp\u003eThis insert is suited for production turning in job shops, aerospace component machining, and general metalworking facilities where both steel (P) and cast iron (K) materials are machined. The neutral hand orientation allows use in standard right- and left-hand toolholders. Maximum depth of cut is 4.00 mm (0.1575 inches), making it appropriate for medium finishing and light roughing passes. It is typically installed by machinists and CNC operators in clamp, lever lock, pin, or screw-style insert holding systems.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eANSI insert code CNMG432 \/ ISO code CNMG120408 for broad toolholder compatibility\u003c\/li\u003e\n\u003cli\u003eCVD-coated ACK20P carbide grade for high wear resistance in steel and cast iron\u003c\/li\u003e\n\u003cli\u003e80-degree diamond (rhombic) insert shape with negative side clearance for rigid, stable cutting\u003c\/li\u003e\n\u003cli\u003e0.80 mm (0.0315 inch) corner radius for balanced edge strength and surface finish\u003c\/li\u003e\n\u003cli\u003eFour cutting edges per insert for extended tooling value\u003c\/li\u003e\n\u003cli\u003eWM+ chip breaker geometry for controlled chip evacuation in general turning\u003c\/li\u003e\n\u003cli\u003eCompatible with clamp, lever lock, pin, and screw insert holding methods\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement turning insert for CNMG432 toolholders accepting negative-rake carbide inserts with a 0.5000-inch inscribed circle and M tolerance class.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThis insert is installed and indexed by qualified machinists or CNC operators following machine tool manufacturer guidelines. Power down and lock out the machine before indexing or replacing inserts. Use the appropriate torque driver or clamping screw specified by the toolholder manufacturer — do not overtighten, as this can fracture the insert. Inspect the toolholder pocket for wear or debris before seating a new insert to ensure proper support and runout.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eANSI Insert Code\u003c\/strong\u003e: CNMG432\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eISO Insert Code\u003c\/strong\u003e: CNMG120408\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: CNMG\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\u003eInsert Material\u003c\/strong\u003e: Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: ACK20P\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: CVD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChip Breaker\u003c\/strong\u003e: WM+\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.80 mm (0.0315 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 12.70 mm (0.5000 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Thickness\u003c\/strong\u003e: 4.76 mm (0.1874 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHole Diameter\u003c\/strong\u003e: 0.2043 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Depth of Cut\u003c\/strong\u003e: 4.00 mm (0.1575 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\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: M\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Hand\u003c\/strong\u003e: Neutral\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSide Clearance\u003c\/strong\u003e: Negative\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Steel (P) - High Wear-Resistance; Cast Iron (K) - High Wear-Resistance to Moderate Wear-Resistance and Toughness\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Holding Method\u003c\/strong\u003e: Clamp; Lever Lock; Pin; Screw\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.03 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: ACCUPRO\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 75332916\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51730438324530,"sku":"75332916","price":176.07,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/dcdcff4b1e5c1e0dae16f056fb5c4c4f.jpg?v=1788717460","url":"https:\/\/voomisupply.com\/products\/accupro-75332916-cnmg432-carbide-turning-insert","provider":"Voomi Supply","version":"1.0","type":"link"}
