It carries the ANSI designation DNMG431MP and ISO code DNMG150404MP, featuring a 55-degree diamond (rhombic) shape with a negative rake and neutral hand orientation. The insert is coated via MTCVD with a multilayer TiCN and Al2O3 coating classified as grade KCM15B, balancing moderate wear resistance with toughness. With four usable cutting edges and an MP chip breaker geometry, it covers roughing and medium machining operations. Licensed HVAC technicians, machinists, and metalworking professionals in production environments are the primary installers of this insert type.\u003c\/p\u003e\u003cp\u003eThis insert is suited for turning, facing, boring, back turning, and back boring operations on steel, stainless steel, superalloys, and titanium workpieces. Grade KCM15B targets ISO material groups P (steel) and M (stainless steel), offering moderate to high wear resistance depending on workpiece material. It is held by clamp or pin methods and is designed for use in KENLOC-compatible toolholders. The ANSI size code 431 and ISO size code 150404 govern toolholder compatibility selection.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eMTCVD multilayer TiCN and Al2O3 coating (grade KCM15B) for wear resistance on steel and stainless steel\u003c\/li\u003e\n\u003cli\u003e55-degree diamond insert shape with negative rake and 0-degree relief angle for rigid, stable cutting\u003c\/li\u003e\n\u003cli\u003eMP chip breaker geometry rated for roughing and medium machining operations\u003c\/li\u003e\n\u003cli\u003eFour usable cutting edges per insert, reducing per-edge tooling cost\u003c\/li\u003e\n\u003cli\u003eCompatible with clamp and pin holding methods in KENLOC-series toolholders\u003c\/li\u003e\n\u003cli\u003eMeets ANSI and ISO insert standards; ANSI code DNMG431MP, ISO code DNMG150404MP\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in KENLOC-series toolholders accepting DNMG431 (ANSI) or DNMG150404 (ISO) inserts with clamp or pin retention.

Seat the insert fully against the toolholder pocket and torque the clamping screw according to the toolholder manufacturer specification before resuming cuts. Inspect the cutting edge and chip breaker for chips or fractures at each index. Follow shop safety and machine guarding requirements when handling carbide inserts, as edges are sharp and carbide is brittle.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eANSI Insert Code\u003c\/strong\u003e: DNMG431MP\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eISO Insert Code\u003c\/strong\u003e: DNMG150404MP\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: KCM15B\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: TiCN and Al2O3 (MTCVD Multilayer CVD)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Material\u003c\/strong\u003e: Solid Carbide\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\u003eInsert Hand\u003c\/strong\u003e: Neutral\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Cutting Edges\u003c\/strong\u003e: 4\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 0.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Length\u003c\/strong\u003e: 15.5 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: 0.0156 inches (1\/64 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Depth of Cut\u003c\/strong\u003e: 0.4065 inches (13\/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\u003eRelief Angle\u003c\/strong\u003e: 0 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRake Angle\u003c\/strong\u003e: 6 degrees 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\u003eSide Clearance\u003c\/strong\u003e: Negative\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: KENLOC\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\u003eStandards\u003c\/strong\u003e: ANSI, ISO\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1 insert per package\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMinimum Order Quantity\u003c\/strong\u003e: 5\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: KENNAMETAL\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 5641098\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51752057209138,"sku":"5641098","price":235.45,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/3d545ee29abbf469b48847c703353120_6f2bc3c8-1db5-4763-9d29-2317c5c94d2f.jpg?v=1788925563","url":"https:\/\/voomisupply.com\/products\/kennametal-5641098-dnmg431mp-turning-insert-kcm15b-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
