The 55-degree diamond shape (Insert Shape Code D) and MF4 chip breaker geometry make this insert well-suited for medium finishing operations. It features a neutral hand orientation, a chamfered and honed cutting edge style, and four usable cutting edges. The inscribed circle measures 0.5 inches, the corner radius is 0.0315 inches (1\/32 inch), and the insert thickness is 0.1875 inches (3\/16 inch). This insert complies with ANSI and ISO standards and carries the ISO designation DNMG150408-MF4.\u003c\/p\u003e\u003cp\u003eThis insert is engineered for primary use on stainless steel (ISO Material Code M) and is also rated for steel (ISO Material Code P) applications. Material grades M25, M30, and M35 define the recommended application range. It is suited for back turning, boring, facing, and turning operations on CNC lathes and turning centers in production and job-shop environments. The MF4 chip breaker geometry supports controlled chip evacuation during light-to-medium depth finishing passes, making it a practical choice for close-tolerance stainless steel components.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eCVD Duratomic multilayer coating (TiCN, Al2O3, Cr) for wear resistance and thermal stability on stainless and steel\u003c\/li\u003e\n\u003cli\u003eFour cutting edges per insert with a 55-degree diamond shape for versatile approach angles\u003c\/li\u003e\n\u003cli\u003eMF4 chip breaker geometry designed for controlled chip flow in medium finishing cuts\u003c\/li\u003e\n\u003cli\u003eNegative rake, chamfered and honed cutting edge for edge strength and consistent surface finish\u003c\/li\u003e\n\u003cli\u003eCompatible with clamp, pin, and lever lock toolholders\u003c\/li\u003e\n\u003cli\u003eConforms to ANSI and ISO standards; ISO code DNMG150408-MF4\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in DNMG-style toolholders that accept clamp, pin, or lever lock insert holding methods with a 0.2028-inch hole diameter.

Power down and lock out the machine spindle before indexing or replacing any cutting insert. Use the appropriate torque wrench and seating screw specified by the toolholder manufacturer when securing the insert clamp or lever lock. Inspect the insert seat and chip pocket for debris before seating a new edge to ensure proper contact and prevent premature edge failure.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: DNMG\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIndustry Standard Number\u003c\/strong\u003e: DNMG432-MF4\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eISO Code\u003c\/strong\u003e: DNMG150408-MF4\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: TM2501\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Material\u003c\/strong\u003e: Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: TiCN, Al2O3, Cr (CVD Duratomic)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Shape\u003c\/strong\u003e: Diamond 55 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIncluded Angle\u003c\/strong\u003e: 55 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Hand\u003c\/strong\u003e: Neutral\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\u003eChip Breaker\u003c\/strong\u003e: MF4\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRake\u003c\/strong\u003e: Negative\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRake Angle\u003c\/strong\u003e: 30 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRelief Angle\u003c\/strong\u003e: 0 degrees\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: 1.2204 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: 0.0315 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHole Diameter\u003c\/strong\u003e: 0.2028 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Depth of Cut\u003c\/strong\u003e: 0.5012 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Holding Method\u003c\/strong\u003e: Clamp, Pin, Lever Lock\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Stainless Steel (Code M)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSecondary Workpiece Material\u003c\/strong\u003e: Steel (Code P)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Grade Range\u003c\/strong\u003e: M25, M30, M35\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMulti-Use Application\u003c\/strong\u003e: Back Turning, Boring, Facing, Turning\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: ANSI, ISO\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Weight\u003c\/strong\u003e: 0.24 pounds\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\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: SECO\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 03276276\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SECO TOOLS","offers":[{"title":"Default Title","offer_id":51560717353266,"sku":"03276276","price":319.49,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/6ccf6318b6802665a7793a8942820e84_91aaee31-4cc2-4a73-bea0-1be68fadda98.jpg?v=1786456094","url":"https:\/\/voomisupply.com\/products\/seco-03276276-dnmg432-mf4-turning-insert-tm2501-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
