It features a multilayer CVD coating of TiN, TiCN, and Al2O3 applied via MTCVD process, delivering a balance of high toughness on steel and moderate wear resistance on stainless steel. The insert has a 55-degree diamond (rhombic) shape, a negative rake angle, and a neutral hand orientation. With four usable cutting edges and an MN chip breaker geometry, it is suited for roughing and medium machining operations. Licensed machinists and CNC operators working in production turning environments are the primary users of this insert.\u003c\/p\u003e\n\u003cp\u003eThis insert is used in external and internal turning operations including facing, boring, back turning, and back boring. Its KENLOC series designation indicates compatibility with toolholders designed for clamp and pin insert holding methods. The MN chip breaker geometry handles interrupted and continuous cuts on steel workpieces, making it a practical choice for both roughing passes and medium-depth finishing work in job shop and production environments. The negative side clearance and chamfered, honed cutting edge style contribute to edge stability under heavier chip loads.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eKCP40 grade multilayer CVD coating (TiN, TiCN, Al2O3) for steel and stainless steel cutting\u003c\/li\u003e\n  \u003cli\u003e55-degree diamond insert shape with 4 cutting edges and neutral hand orientation\u003c\/li\u003e\n  \u003cli\u003eMN chip breaker supports roughing and medium machining operations\u003c\/li\u003e\n  \u003cli\u003eANSI code DNMG432 \/ ISO code DNMG150408 for standardized toolholder fit\u003c\/li\u003e\n  \u003cli\u003eChamfered and honed cutting edge style for edge strength and stability\u003c\/li\u003e\n  \u003cli\u003eCompatible with clamp and pin insert holding methods\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in KENLOC series toolholders that accept DNMG432 (ISO DNMG150408) inserts using clamp or pin holding methods.

Power down and lock out the machine spindle before seating or replacing the insert. Ensure the insert pocket and seating surface are clean and free of chips before clamping. Do not exceed the maximum depth of cut specified for the insert geometry, and verify toolholder torque specifications against the toolholder manufacturer documentation.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eANSI Insert Code\u003c\/strong\u003e: DNMG432\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eISO Insert Code\u003c\/strong\u003e: DNMG150408\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: KCP40\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Shape\u003c\/strong\u003e: D - Diamond (Rhombic) 55-Degree\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eIncluded Angle\u003c\/strong\u003e: 55 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 0.5000 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Length\u003c\/strong\u003e: 15.50 mm (1.2208 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Thickness\u003c\/strong\u003e: 0.1875 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.0313 inches (1\/32 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHole Diameter\u003c\/strong\u003e: 0.2031 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Depth of Cut\u003c\/strong\u003e: 1.25 mm (0.0492 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: TiN, TiCN, Al2O3 (Multilayer CVD - MTCVD)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating Classification\u003c\/strong\u003e: CVD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChip Breaker\u003c\/strong\u003e: MN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChip Breaker Operation\u003c\/strong\u003e: Roughing, Medium Machining\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\u003eRake Angle\u003c\/strong\u003e: 0 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRelief Angle\u003c\/strong\u003e: 0 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSide Clearance\u003c\/strong\u003e: Negative\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Holding Method\u003c\/strong\u003e: Clamp, Pin\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Steel (P), Stainless Steel (M)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGrade Characteristics\u003c\/strong\u003e: Steel (P) - High Toughness, Stainless Steel (M) - Moderate Wear Resistance and Toughness\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: C5, C6\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMulti-Use Application\u003c\/strong\u003e: Turning, Facing, Boring, Back Turning, Back Boring\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: KENLOC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: ANSI, ISO\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Edge Style\u003c\/strong\u003e: Chamfered, Honed\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.2 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Order Quantity\u003c\/strong\u003e: 5\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: KENNAMETAL\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 3751814\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51739327398194,"sku":"3751814","price":235.45,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/47ca74a9a4338f756acada825a92e66f.jpg?v=1788813182","url":"https:\/\/voomisupply.com\/products\/kennametal-3751814-dnmg432mn-kcp40-turning-insert","provider":"Voomi Supply","version":"1.0","type":"link"}
