It carries ANSI insert code DNGP431 and ISO insert code DNGP150404. The insert features a 55-degree diamond (rhombic) shape, a 0.40 mm (0.0157 inch) corner radius, and a neutral hand orientation, making it suitable for both right- and left-hand toolholders. Manufactured in the ACM20K grade with a PVD coating and EXK+ chip breaker geometry, it delivers high wear resistance with moderate toughness across a range of turning applications. Machinists and CNC operators install this insert when working stainless steel and cast iron workpieces.\u003c\/p\u003e\n\u003cp\u003eThis insert is rated for primary workpiece material codes M (stainless steel) and K (cast iron), covering applications from finishing to semi-finishing passes. The ACM20K grade characteristics target high-to-moderate wear resistance and toughness in both material groups, making it a practical choice for job shops and production environments running stainless components or gray and ductile iron parts. Maximum depth of cut is 2.50 mm (0.0984 inches). The insert is compatible with clamp, lever lock, pin, and screw holding methods, providing flexibility across common toolholder systems.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eDNGP diamond (rhombic) 55-degree insert shape with negative side clearance for stable, rigid cutting\u003c\/li\u003e\n  \u003cli\u003eACM20K carbide grade with PVD coating for extended tool life on stainless steel and cast iron\u003c\/li\u003e\n  \u003cli\u003eEXK+ chip breaker geometry for effective chip control during semi-finishing and finishing passes\u003c\/li\u003e\n  \u003cli\u003eNeutral hand orientation compatible with right- and left-hand toolholders\u003c\/li\u003e\n  \u003cli\u003eFour cutting edges per insert to reduce per-edge tooling cost\u003c\/li\u003e\n  \u003cli\u003eCompatible with clamp, lever lock, pin, and screw holding methods\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in DNGP-style toolholders accepting a 0.5000-inch (12.70 mm) inscribed circle insert with a 0.2043-inch hole diameter and negative clearance geometry.

Always index or replace inserts with the machine fully stopped and the spindle locked. Seat the insert firmly against the toolholder pocket before tightening the clamping mechanism to the toolholder manufacturer's specified method. Inspect the insert pocket for chips or debris before seating to avoid cracking the carbide substrate.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eANSI Insert Code\u003c\/strong\u003e: DNGP431\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eISO Insert Code\u003c\/strong\u003e: DNGP150404\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: DNGP\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Shape\u003c\/strong\u003e: D - Diamond (Rhombic) 55 Degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: ACM20K\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: PVD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChip Breaker\u003c\/strong\u003e: EXK+\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Material\u003c\/strong\u003e: Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eIncluded Angle\u003c\/strong\u003e: 55 degrees\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 (Negative)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTolerance Code\u003c\/strong\u003e: G\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.40 mm (0.0157 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 0.5000 inches (12.70 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Thickness\u003c\/strong\u003e: 0.1874 inches (4.76 mm)\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: 0.0984 inches (2.50 mm)\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 Hand\u003c\/strong\u003e: Neutral\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\u003ePrimary Workpiece Material\u003c\/strong\u003e: Stainless Steel (M), Cast Iron (K)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: CI\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: 10\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.03 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23242105\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: ACCUPRO\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 75392399\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51727126004018,"sku":"75392399","price":341.77,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/5eaf11f7c48a1685026ee12d8342b897.jpg?v=1788673765","url":"https:\/\/voomisupply.com\/products\/accupro-75392399-dngp431-carbide-turning-insert","provider":"Voomi Supply","version":"1.0","type":"link"}
