It features a multilayer CVD coating — TiCN, Al2O3, and TiOCN — engineered to balance toughness and wear resistance across demanding cut conditions. The insert has a 55-degree diamond (rhombic) shape, a neutral hand orientation, a 0.5 inch inscribed circle, and a 1\/32 inch (0.0313 inch) corner radius. Insert length is 15.50 mm (1.2208 inches) and thickness is 3\/16 inch (0.1875 inch). The MP chip breaker geometry supports both roughing and medium machining operations. It is installed and replaced by machinists and CNC lathe operators working in production or job-shop environments.\u003c\/p\u003e\u003cp\u003eThis insert is designed for turning, facing, boring, back turning, and back boring operations. Primary workpiece materials are steel (P-grade), stainless steel (M-grade), and superalloys and titanium. The KCM25B grade provides high toughness for steel and moderate wear resistance and toughness for stainless steel applications. The four available cutting edges and negative rake angle make it a cost-effective choice for medium to heavy chip loads on CNC lathes and manual turning centers where insert security and edge stability are priorities.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eMultilayer CVD coating: TiCN, Al2O3, and TiOCN for wear resistance and toughness\u003c\/li\u003e\n\u003cli\u003e55-degree diamond (rhombic) insert shape with negative rake and negative side clearance\u003c\/li\u003e\n\u003cli\u003eMP chip breaker supports roughing and medium machining chip control\u003c\/li\u003e\n\u003cli\u003eFour cutting edges for extended tool life per insert\u003c\/li\u003e\n\u003cli\u003eCompatible insert holding methods: clamp and pin\u003c\/li\u003e\n\u003cli\u003eMaximum depth of cut: 13\/32 inch (0.4065 inch)\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in KENLOC-series toolholders accepting DNMG432 inserts with clamp or pin holding.

Use the appropriate torque wrench or clamp screw tool specified for the KENLOC toolholder to seat the insert; do not overtighten the clamp screw by feel alone. Inspect the insert pocket for chips or debris before seating a new edge. Confirm insert orientation matches the neutral hand designation of the toolholder before resuming operation.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\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: DNMG150408MP\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\u003eGrade\u003c\/strong\u003e: KCM25B\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: TiCN, Al2O3, TiOCN (Multilayer CVD, MTCVD process)\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: MP (Roughing and Medium Machining)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 0.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.0313 inches (1\/32 inch)\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 inch)\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: 0.4065 inches (13\/32 inch)\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: 6 degrees (Negative)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSide Clearance\u003c\/strong\u003e: Negative\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Edge Style\u003c\/strong\u003e: Chamfered and 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, Stainless Steel, Superalloys and Titanium\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Material\u003c\/strong\u003e: Solid Carbide\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\u003eWeight\u003c\/strong\u003e: 0.3042 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: KENNAMETAL\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 5591782\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51754764468530,"sku":"5591782","price":237.15,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/3d545ee29abbf469b48847c703353120_293e1623-5529-4714-9d6f-2ca591d10423.jpg?v=1788948544","url":"https:\/\/voomisupply.com\/products\/kennametal-5591782-dnmg432mp-turning-insert-kcm25b","provider":"Voomi Supply","version":"1.0","type":"link"}
