Identified by industry-standard code TCMT3251LF (ISO: TCMT16T304LF), it carries the KCP25B grade designation and features a multilayer CVD coating stack of TiCN, Al2O3, and TiOCN applied via MTCVD process. The LF chip breaker geometry targets finishing and light machining applications. The insert measures 0.6495 inches in length with a 3\/8-inch inscribed circle, a 1\/64-inch corner radius, and a 5\/32-inch thickness. It is mounted via screw-on holding method and provides three usable cutting edges, offering neutral hand orientation and a positive rake and side clearance geometry.\u003c\/p\u003e\u003cp\u003eThis insert is suited for finishing and light machining passes on steel and cast iron workpieces, as well as aluminum and non-ferrous materials. The KCP25B grade delivers moderate wear resistance combined with toughness, making it appropriate for stable cuts where surface finish and edge consistency are priorities. It is used by machinists and tooling technicians in job shops, production turning cells, and aerospace or general metalworking environments. The screw-on mounting style is compatible with standard TCMT-style toolholders.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eKCP25B grade with multilayer CVD TiCN \/ Al2O3 \/ TiOCN coating for wear resistance on steel and cast iron\u003c\/li\u003e\n\u003cli\u003eLF chip breaker optimized for finishing and light machining operations\u003c\/li\u003e\n\u003cli\u003ePositive rake angle of 5 degrees and positive side clearance for reduced cutting forces\u003c\/li\u003e\n\u003cli\u003eThree usable cutting edges per insert for extended tooling value\u003c\/li\u003e\n\u003cli\u003eNeutral hand orientation fits standard TCMT screw-on toolholders\u003c\/li\u003e\n\u003cli\u003eHoned cutting edge style for consistent edge strength on light depths of cut\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in standard TCMT-style screw-on toolholders.

Power down and lock out the machine spindle before seating or indexing the insert. Confirm the insert pocket and clamping screw are clean and free of chips before tightening to prevent seating errors. Do not exceed the maximum recommended depth of cut of 0.2163 inches for this insert geometry.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eANSI Insert Code\u003c\/strong\u003e: TCMT3251\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eISO Insert Code\u003c\/strong\u003e: TCMT16T304\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIndustry Standard Number\u003c\/strong\u003e: TCMT3251LF\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eISO Full Code\u003c\/strong\u003e: TCMT16T304LF\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: KCP25B\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: TiCN \/ Al2O3 \/ TiOCN (Multilayer CVD)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating Process\u003c\/strong\u003e: MTCVD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Shape\u003c\/strong\u003e: T - Triangle, 60 degrees included angle\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChip Breaker\u003c\/strong\u003e: LF (Finishing \/ Light Machining)\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: Positive\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRake Angle\u003c\/strong\u003e: 5 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSide Clearance\u003c\/strong\u003e: Positive\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRelief Angle\u003c\/strong\u003e: 7 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Edge Style\u003c\/strong\u003e: Honed\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Cutting Edges\u003c\/strong\u003e: 3\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 3\/8 inch (0.3750 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Length\u003c\/strong\u003e: 0.6495 inches (16.50 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Thickness\u003c\/strong\u003e: 5\/32 inch (0.1563 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 1\/64 inch (0.0156 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHole Diameter\u003c\/strong\u003e: 0.1732 inches (4.40 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Depth of Cut\u003c\/strong\u003e: 0.2163 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Holding Method\u003c\/strong\u003e: Screw-On\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Steel, Cast Iron, Aluminum, Non-Ferrous\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eApplication\u003c\/strong\u003e: Turning, Facing, Boring\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: ANSI, ISO\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: C2, C3, C6, C7\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.0141 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: 5698120\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51747085123890,"sku":"5698120","price":242.31,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/7278cb0b5284e66aa700eeb825becf0c_2088dffe-d8bf-4005-a318-c2aba5eeef69.jpg?v=1788875882","url":"https:\/\/voomisupply.com\/products\/kennametal-5698120-tcmt3251lf-carbide-turning-insert","provider":"Voomi Supply","version":"1.0","type":"link"}
