It carries a multilayer CVD coating — TiCN, Al2O3, and TiOCN — engineered for high wear resistance on steel and cast iron workpiece materials. The insert features an 80-degree diamond (rhombic) shape, a neutral hand orientation, and a positive rake and positive side clearance geometry. The LF chip breaker is optimized for finishing and light machining operations. Two cutting edges are available per insert. The screw-on holding method provides secure, repeatable seating in compatible toolholders. Installation is performed by licensed machinists and tooling technicians operating CNC or manual turning equipment.\u003c\/p\u003e\u003cp\u003eThis insert is suited for turning, facing, and boring operations in both steel (ISO P) and cast iron (ISO K) applications. Its KCK20B grade delivers high wear resistance against steel and a balance of wear resistance and toughness against cast iron. The finishing-oriented LF chip breaker geometry targets light material removal rates and tight surface finish requirements. Typical applications include component finishing passes on carbon steel, alloy steel, and gray or ductile cast iron in production or job-shop environments.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eMultilayer CVD coating (TiCN \/ Al2O3 \/ TiOCN) for high wear resistance in steel and cast iron\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\u003eLF chip breaker optimized for finishing and light machining\u003c\/li\u003e\n\u003cli\u003eNeutral hand orientation compatible with both left- and right-hand toolholders\u003c\/li\u003e\n\u003cli\u003eTwo usable cutting edges per insert for extended tool life value\u003c\/li\u003e\n\u003cli\u003eScrew-on holding method for accurate, repeatable insert indexing\u003c\/li\u003e\n\u003cli\u003eConforms to ANSI and ISO standards for broad toolholder compatibility\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in screw-on CCMT-style toolholders conforming to ANSI size code 3252 and ISO size code 09T308.

Power down and lock out all machine spindles before changing inserts. Inspect the toolholder pocket for chips, wear, or damage before seating the new insert. Handle carbide inserts with care — edges are sharp and the substrate is brittle under impact.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eANSI Insert Code\u003c\/strong\u003e: CCMT3252\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eISO Insert Code\u003c\/strong\u003e: CCMT09T308\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIndustry Standard Number\u003c\/strong\u003e: CCMT3252LF\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eISO Code\u003c\/strong\u003e: CCMT09T308LF\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: KCK20B\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: C - Diamond (Rhombic) 80 degrees\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\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\u003eRake Angle\u003c\/strong\u003e: 5 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: 2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Holding Method\u003c\/strong\u003e: Screw-On\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\u003eCorner Radius\u003c\/strong\u003e: 1\/32 inches (0.0313 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\u003eWidth\u003c\/strong\u003e: 3\/8 inches (0.3750 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: 0.1268 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Steel (P), Cast Iron (K)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGrade Characteristics\u003c\/strong\u003e: High Wear Resistance for Steel; High to Moderate Wear Resistance and Toughness for Cast Iron\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\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: 0.01 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: ANSI, ISO\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: 5641237\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51732824097074,"sku":"5641237","price":183.93,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/bbcdc5a197e23376d317549ec2aa8d41_1a27843d-deb4-41b7-907b-72be7c218ca3.jpg?v=1788747221","url":"https:\/\/voomisupply.com\/products\/kennametal-5641237-ccmt3252lf-turning-insert-kck20b","provider":"Voomi Supply","version":"1.0","type":"link"}
