The insert features an 80-degree diamond (rhombic) shape with a positive rake angle of 15 degrees and a 7-degree relief angle, promoting clean chip evacuation and reduced cutting forces. The carbide substrate is coated with AlTiN via a PVD process, providing moderate wear resistance and toughness across a range of workpiece materials. With a 3\/8-inch inscribed circle and a 1\/64-inch corner radius, this insert is suited to finishing passes where dimensional accuracy and surface finish are priorities. Licensed machinists and CNC operators install this insert on screw-on style toolholders.\u003c\/p\u003e\n\u003cp\u003eThis insert is built for finishing applications including turning, facing, and boring. Primary workpiece materials include steel, stainless steel, cast iron, aluminum and non-ferrous alloys, and superalloys including titanium. The KCU25 grade offers a balanced profile of wear resistance and toughness, making it a versatile choice for shops that run varied materials. The neutral hand orientation suits standard right-hand and left-hand toolholder setups. Two cutting edges are available per insert, supporting cost-effective edge utilization on production runs.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCCMT3251FP geometry with FP chip breaker optimized for finishing cuts\u003c\/li\u003e\n  \u003cli\u003eAlTiN PVD coating for moderate wear resistance across steel, stainless, cast iron, and non-ferrous materials\u003c\/li\u003e\n  \u003cli\u003e80-degree diamond insert shape with positive rake and positive side clearance for reduced cutting forces\u003c\/li\u003e\n  \u003cli\u003e3\/8-inch inscribed circle and 1\/64-inch corner radius for tight-tolerance finishing passes\u003c\/li\u003e\n  \u003cli\u003e2 usable cutting edges per insert for extended tool life value\u003c\/li\u003e\n  \u003cli\u003eScrew-on holding method compatible with standard CCMT toolholder pockets\u003c\/li\u003e\n  \u003cli\u003eConforms to ANSI and ISO standards (ANSI: CCMT3251, ISO: CCMT09T304)\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in screw-on style CCMT toolholders conforming to ANSI insert code CCMT3251 and ISO insert code CCMT09T304.

Power down and lock out the machine before changing inserts. Seat the insert fully into the toolholder pocket and secure with the clamping screw to the toolholder manufacturer's specified procedure before resuming cuts. Inspect the seating pocket for chips or wear debris before installing a new edge, as debris under the insert affects dimensional accuracy.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eANSI Insert Code\u003c\/strong\u003e: CCMT3251\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eISO Insert Code\u003c\/strong\u003e: CCMT09T304\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Shape\u003c\/strong\u003e: C - Diamond (Rhombic) 80 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: KCU25\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: AlTiN (PVD Process)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Material\u003c\/strong\u003e: Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChip Breaker\u003c\/strong\u003e: FP (Finishing)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 3\/8 inches (0.3750 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Length\u003c\/strong\u003e: 9.67 mm (0.3808 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Thickness\u003c\/strong\u003e: 5\/32 inches (0.1563 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 1\/64 inches (0.0156 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Depth of Cut\u003c\/strong\u003e: 0.1268 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\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\u003eSide Clearance\u003c\/strong\u003e: Positive\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: 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\u003eHolding Method\u003c\/strong\u003e: Screw-On\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Materials\u003c\/strong\u003e: Steel, Stainless Steel, Cast Iron, Aluminum and Non-Ferrous, Superalloys and Titanium\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: C2, C6\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: ANSI, ISO\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1 insert per package\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Order Quantity\u003c\/strong\u003e: 5\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.1 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: 3769417\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51727306195250,"sku":"3769417","price":212.25,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/ceab44dc84c9d19479517ca6255751a3.jpg?v=1788676117","url":"https:\/\/voomisupply.com\/products\/kennametal-3769417-turning-insert-ccmt3251fp-kcu25-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
