It carries the ANSI insert designation CCGT21505HP and the ISO equivalent CCGT060202, with manufacturer grade KC5025 and a PVD-applied TiAlN coating. The insert features an 80-degree diamond (rhombic) shape, a positive rake angle of 15 degrees, and a honed cutting edge style. With a 0.25-inch inscribed circle and a corner radius of 0.0079 inches, it is built for light, accurate finishing cuts. Licensed machinists and CNC lathe operators install this insert in screw-on toolholders for turning, facing, and boring applications.\u003c\/p\u003e\u003cp\u003eThis insert is suited for finishing passes on stainless steel, superalloys, titanium, steel, cast iron, aluminum, and other non-ferrous materials. The KC5025 grade provides moderate wear resistance and toughness across material categories P, M, K, N, and S per ISO classification. Typical applications include light-depth finishing cuts on precision turned components in job shops, aerospace machining cells, and general metalworking environments where tight tolerances and surface finish are priorities. The HP chip breaker geometry supports chip control at finishing parameters.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eANSI code CCGT21505HP with ISO equivalent CCGT060202 for toolholder compatibility verification\u003c\/li\u003e\n\u003cli\u003eKC5025 grade with PVD TiAlN coating for wear resistance on stainless steel and superalloys\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\u003eHP chip breaker optimized for finishing operations and effective chip evacuation\u003c\/li\u003e\n\u003cli\u003eScrew-on holding method with a 0.1102-inch hole diameter for secure clamping\u003c\/li\u003e\n\u003cli\u003eNeutral hand orientation and multi-use design supports turning, facing, and boring on a single insert\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in screw-on style toolholders accepting CCGT-style inserts with a 0.25-inch inscribed circle.

Power down and lock out the machine before indexing or replacing inserts. Use the appropriate torx or hex key to secure the clamping screw to the toolholder manufacturer's specified procedure — do not overtighten, as carbide inserts are brittle. Inspect the insert seat and shim for damage before seating a new insert.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eANSI Insert Code\u003c\/strong\u003e: CCGT21505\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eISO Insert Code\u003c\/strong\u003e: CCGT060202\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: KC5025\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: TiAlN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating Process\u003c\/strong\u003e: PVD\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\u003eInscribed Circle\u003c\/strong\u003e: 0.25 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Length\u003c\/strong\u003e: 6.45 mm (0.2543 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Thickness\u003c\/strong\u003e: 0.0938 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\u003eHole Diameter\u003c\/strong\u003e: 0.1102 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Depth of Cut\u003c\/strong\u003e: 1.25 mm (0.0492 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: HP\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Hand\u003c\/strong\u003e: Neutral\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSide Clearance\u003c\/strong\u003e: Positive\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Holding Method\u003c\/strong\u003e: Screw-On\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Cutting Edges\u003c\/strong\u003e: 2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Stainless Steel, Superalloys, Titanium\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompatible Material Categories (ISO)\u003c\/strong\u003e: P, M, K, N, S\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChip Breaker Operation\u003c\/strong\u003e: Finishing\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMulti-Use Application\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\u003eWeight\u003c\/strong\u003e: 0.022 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: 1866955\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51734727065906,"sku":"1866955","price":200.81,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/12a67782c03490c542ef37eb72617339.jpg?v=1788766156","url":"https:\/\/voomisupply.com\/products\/kennametal-1866955-ccgt21505hp-kc5025-carbide-turning-insert","provider":"Voomi Supply","version":"1.0","type":"link"}
