The insert features a multilayer MTCVD coating of TiCN and Al2O3, which provides wear resistance and thermal stability during continuous and interrupted cuts in steel and cast iron. The 55-degree diamond shape (DNMA) delivers a strong cutting edge suitable for roughing and semi-finishing passes. At 15.5 mm in length with a 0.5-inch inscribed circle and a 0.03125-inch corner radius, this insert fits standard KENLOC-style toolholders with clamp and pin retention.\u003c\/p\u003e\n\u003cp\u003eThis insert is used in turning, facing, boring, back turning, and back boring operations on steel and cast iron workpieces. It is suited for both residential shop and industrial production environments where consistent chip control and tool life are priorities. The flat-top chip breaker and honed cutting edge make it appropriate for moderate to heavy material removal on ferrous materials. The negative rake geometry and neutral hand orientation allow flexible placement in a range of DNMA-compatible toolholder setups.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eMTCVD multilayer TiCN and Al2O3 coating for extended wear resistance in steel and cast iron\u003c\/li\u003e\n  \u003cli\u003e55-degree diamond insert shape (DNMA) with negative rake angle for strong edge support\u003c\/li\u003e\n  \u003cli\u003eFour cutting edges per insert for maximum value per piece\u003c\/li\u003e\n  \u003cli\u003eFlat-top chip breaker with honed cutting edge style for consistent chip formation\u003c\/li\u003e\n  \u003cli\u003eMaximum depth of cut of 1.25 mm (0.0492 inches) for controlled material removal\u003c\/li\u003e\n  \u003cli\u003eCompatible with clamp and pin insert holding methods in KENLOC-style toolholders\u003c\/li\u003e\n  \u003cli\u003eMeets ANSI and ISO standards; insert size code 432\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in KENLOC-series toolholders that accept DNMA-style inserts with clamp and pin retention.

Ensure the machine spindle is fully stopped and the turret is in a safe index position before seating or replacing the insert. Use the correct clamp and pin hardware specified for DNMA432 KENLOC toolholders; do not overtighten the clamp screw beyond the toolholder manufacturer's torque specification. Inspect the seating pocket for chips or debris before securing the insert to ensure proper contact and edge alignment.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: DNMA\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eIndustry Standard Number\u003c\/strong\u003e: DNMA432\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: KCK05\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: TiCN and Al2O3 (Multilayer MTCVD CVD)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Shape\u003c\/strong\u003e: Diamond 55 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 0.5 inches (0.5000 inches decimal)\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 (3\/16 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.03125 inches (1\/32 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHole Diameter\u003c\/strong\u003e: 0.2031 inches (5.16 mm)\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\u003eNumber of Cutting Edges\u003c\/strong\u003e: 4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRake Angle\u003c\/strong\u003e: 0 degrees (Negative Rake)\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\u003eChip Breaker\u003c\/strong\u003e: Flat Top\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Edge Style\u003c\/strong\u003e: Honed\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Holding Method\u003c\/strong\u003e: Clamp and Pin\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Steel, Cast Iron\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: KENLOC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: C3, C4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: ANSI, ISO\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.2 pounds\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: 3751910\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51744020824370,"sku":"3751910","price":237.33,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/ccb0c2111a08311eb5634b8a3e2a0160.jpg?v=1788853046","url":"https:\/\/voomisupply.com\/products\/kennametal-3751910-dnma432-turning-insert-kck05-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
