The insert features a 55-degree diamond (rhombic) shape with a 0.3750-inch inscribed circle and a 0.0079-inch corner radius, enabling tight-tolerance work on contoured and profiled surfaces. A multilayer MTCVD coating — TiCN, Al2O3, and TiOCN — delivers high toughness on steel and moderate wear resistance on stainless steel. The FP chip breaker geometry is optimized for finishing cuts, and the honed cutting edge supports consistent surface finish results. Licensed machinists and CNC operators install and index this insert as part of a screw-on toolholder system.\u003c\/p\u003e\n\u003cp\u003eThis insert is suited for finishing passes in both residential shop and industrial production environments. Primary workpiece materials are steel, stainless steel, superalloys, and titanium. The neutral hand orientation and positive rake angle (15 degrees) make it versatile across turning, facing, boring, back turning, and back boring applications. With two cutting edges per insert and a maximum depth of cut of 0.3049 inches, it supports efficient use in high-mix or production turning programs. It complies with both ANSI and ISO standards, also identified by ISO code DCMT11T302.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e55-degree diamond insert shape for access to contoured profiles and shoulders\u003c\/li\u003e\n  \u003cli\u003eMultilayer MTCVD coating (TiCN, Al2O3, TiOCN) for toughness on steel and wear resistance on stainless\u003c\/li\u003e\n  \u003cli\u003eFP chip breaker geometry optimized for finishing operations\u003c\/li\u003e\n  \u003cli\u003ePositive rake angle (15 degrees) and honed cutting edge for clean surface finish\u003c\/li\u003e\n  \u003cli\u003eNeutral hand — compatible with right- and left-hand toolholder setups\u003c\/li\u003e\n  \u003cli\u003eTwo usable cutting edges per insert\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for screw-on style toolholders accepting DCMT-style inserts per ANSI and ISO standards.

Power down and lock out the machine spindle before indexing or replacing inserts. Seat the insert fully against the toolholder pocket and tighten the clamping screw to the toolholder manufacturer's specified torque using the appropriate Torx or hex key. Inspect the cutting edge and chip breaker for damage before each use; do not run a chipped or cracked insert.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eANSI Insert Code\u003c\/strong\u003e: DCMT32505\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eISO Insert Code\u003c\/strong\u003e: DCMT11T302\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\u003eInscribed Circle\u003c\/strong\u003e: 0.3750 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.0079 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Thickness\u003c\/strong\u003e: 0.1563 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Length\u003c\/strong\u003e: 0.9156 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Depth of Cut\u003c\/strong\u003e: 0.3049 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHole Diameter\u003c\/strong\u003e: 0.1732 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRelief Angle\u003c\/strong\u003e: 7 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRake Angle\u003c\/strong\u003e: 15 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Edge Style\u003c\/strong\u003e: Honed\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChip Breaker\u003c\/strong\u003e: FP (Finishing)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Hand\u003c\/strong\u003e: Neutral\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: TiCN, Al2O3, TiOCN (Multilayer MTCVD CVD)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Steel, Stainless Steel, Superalloys, Titanium\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Cutting Edges\u003c\/strong\u003e: 2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHolding Method\u003c\/strong\u003e: Screw-On\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSide Clearance\u003c\/strong\u003e: Positive\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: 0.1455 pounds\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: 5591129\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51731341771058,"sku":"5591129","price":169.68,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/44a2584664661a26b489e6353899132e.jpg?v=1788729814","url":"https:\/\/voomisupply.com\/products\/kennametal-5591129-dcmt32505fp-kcm25b-carbide-turning-insert","provider":"Voomi Supply","version":"1.0","type":"link"}
