It features a 55-degree diamond (rhombic) insert shape, a 0.5 inch inscribed circle, and a 1\/32 inch corner radius. The cutting edges are chamfered and honed with a flat-top chip breaker geometry and a negative rake angle. An AlTiN PVD coating provides high wear resistance when machining hard materials and special or super alloys. This insert is a multi-tipped, neutral-hand design intended for use by machinists and CNC turning specialists on horizontal and vertical turning centers.\u003c\/p\u003e\n\u003cp\u003eThis insert is suited for hard turning, facing, boring, back turning, and back boring operations. Primary workpiece material categories are hard materials and special or super alloys, corresponding to ISO material groups K and S. Typical applications include finishing and semi-finishing passes on hardened steels, cast irons, and heat-resistant alloys where CBN tooling is the preferred solution over carbide. The insert conforms to both ANSI and ISO standards, with ANSI code DNGA432 and ISO code DNGA150408.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003ePCBN insert material with AlTiN PVD coating for high wear resistance in hard material and super alloy turning\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\u003eChamfered and honed cutting edge preparation reduces edge chipping on interrupted cuts\u003c\/li\u003e\n  \u003cli\u003eFlat-top chip breaker geometry suits finishing and light semi-finishing depths of cut up to 13\/32 inch\u003c\/li\u003e\n  \u003cli\u003eTwo cutting edges per insert; neutral hand fits left- or right-hand toolholders\u003c\/li\u003e\n  \u003cli\u003eCompatible with clamp and pin insert-holding methods per KENLOC series toolholders\u003c\/li\u003e\n  \u003cli\u003eMeets ANSI and ISO insert standards for drop-in toolholder compatibility\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in KENLOC series toolholders accepting DNGA-style inserts with clamp or pin holding.

Seat the insert fully against the toolholder pocket walls and torque the clamp or pin fastener according to the toolholder manufacturer specification before initiating any cut. Inspect the cutting edge and coating condition before each use; do not continue running a visibly chipped or worn edge. Handle PCBN inserts with care to avoid impact against hard surfaces, as the material is brittle despite its hardness.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Material\u003c\/strong\u003e: Polycrystalline Cubic Boron Nitride (PCBN)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: KB5630\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eIndustry Standard Number\u003c\/strong\u003e: DNGA432S0425MT\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eANSI Insert Code\u003c\/strong\u003e: DNGA432\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eISO Insert Code\u003c\/strong\u003e: DNGA150408\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\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 Thickness\u003c\/strong\u003e: 0.1875 inches (3\/16 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Length\u003c\/strong\u003e: 1.2208 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\u003eMaximum Depth of Cut\u003c\/strong\u003e: 0.4065 inches (13\/32 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: AlTiN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating Process\u003c\/strong\u003e: PVD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRake Angle\u003c\/strong\u003e: 0 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRelief Angle\u003c\/strong\u003e: 0 degrees\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: Chamfered and Honed\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Cutting Edges\u003c\/strong\u003e: 2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Hand\u003c\/strong\u003e: Neutral\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\u003eSeries\u003c\/strong\u003e: KENLOC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Hard Material, Special and Super Alloys\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: H25, H35\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMulti-Use Application\u003c\/strong\u003e: Turning, Facing, Boring, Back Turning, Back Boring\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: 0.0176 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\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: 3747225\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51743307825458,"sku":"3747225","price":195.62,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/734bd24c64f776ea5a1aa7df7780d0d5.jpg?v=1788845414","url":"https:\/\/voomisupply.com\/products\/kennametal-3747225-pcbn-turning-insert-dnga432","provider":"Voomi Supply","version":"1.0","type":"link"}
