Designated grade AH6225, it features a 55-degree diamond shape, a neutral hand orientation, and a chamfered and honed cutting edge style. The insert carries a negative rake angle of -10 degrees and provides four usable cutting edges per insert. With a 0.5-inch inscribed circle and a 0.016-inch corner radius, it is sized for medium-duty material removal in both roughing and finishing passes. Licensed machinists and CNC turning specialists install this insert in compatible toolholders on lathes and machining centers.\u003c\/p\u003e\u003cp\u003eThis insert is rated for primary use on steel (ISO material code P) and stainless steel (ISO material code M), covering material grades P20, P30, M20, and M30. It supports turning, facing, boring, back turning, and back boring operations, making it adaptable across a range of lathe and live-tooling setups. Maximum depth of cut reaches 0.1575 inches, and the insert accommodates length-range applications from 0.7 to 10 inches. Its SM chip breaker geometry is suited to controlled chip formation in continuous and interrupted cuts on ferrous alloys.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eMultilayer PVD coating: TiAlN plus TiCN for thermal resistance and wear control on ferrous materials\u003c\/li\u003e\n\u003cli\u003eAH6225 carbide grade covers P20, P30, M20, and M30 material classifications\u003c\/li\u003e\n\u003cli\u003eFour cutting edges per insert for extended tool life per unit\u003c\/li\u003e\n\u003cli\u003eSM chip breaker geometry promotes reliable chip evacuation in steel and stainless turning\u003c\/li\u003e\n\u003cli\u003eChamfered and honed edge prep reduces micro-chipping at entry and during interrupted cuts\u003c\/li\u003e\n\u003cli\u003eNeutral hand designation fits standard DNMG-style toolholders with clamp or pin holding\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement and direct-fit insert for DNMG-series toolholders that accept a 55-degree diamond insert with clamp or pin holding, conforming to ANSI and ISO standards under ISO designation DNMG150404-SM and industry standard number DNMG 431 SM.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by a qualified machinist or CNC tooling technician. Power down and lock out the machine spindle before seating or replacing any indexable insert. Verify the toolholder pocket and clamping hardware are free of chips and debris before positioning the insert. Do not exceed the recommended depth of cut for the workpiece material grade, and always confirm clamp torque against the toolholder manufacturer's specification.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: DNMG431SM\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: AH6225\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: TiAlN and TiCN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating Process\u003c\/strong\u003e: PVD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating Classification\u003c\/strong\u003e: Multilayer\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Shape\u003c\/strong\u003e: 55-degree Diamond (Code D)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Hand\u003c\/strong\u003e: Neutral\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRake\u003c\/strong\u003e: Negative (-10 degrees)\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: 0.0157 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Length\u003c\/strong\u003e: 1.22 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\u003eHole Diameter\u003c\/strong\u003e: 0.203 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Depth of Cut\u003c\/strong\u003e: 0.1575 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\u003eChip Breaker\u003c\/strong\u003e: SM\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\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Grades\u003c\/strong\u003e: P20, P30, M20, M30\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eApplications\u003c\/strong\u003e: Turning, Facing, Boring, Back Turning, Back Boring\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eISO Code\u003c\/strong\u003e: DNMG150404-SM\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: 0.32 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: TUNGALOY\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 6825573\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"TUNGALOY","offers":[{"title":"Default Title","offer_id":51972281041202,"sku":"6825573","price":281.19,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/a3aba9b5f277f396ee22c0c316332cd2.jpg?v=1789965571","url":"https:\/\/voomisupply.com\/products\/tungaloy-6825573-dnmg431sm-ah6225-turning-insert","provider":"Voomi Supply","version":"1.0","type":"link"}
