Coated with a multilayer PVD AlTiN\/AlCrN finish under the KCK20 grade, it delivers high wear resistance when machining steel and cast iron. The 80-degree diamond (rhombic) shape provides a strong cutting edge geometry, while the positive rake angle of 5 degrees and honed cutting edge style support stable, consistent chip formation. With an inscribed circle of 0.375 inches, an insert length of 9.67 mm (0.3808 inches), and a corner radius of 1\/64 inch (0.0156 inches), this insert is engineered for finishing and light machining operations. It seats via screw-on insert holding in compatible toolholders.\u003c\/p\u003e\u003cp\u003eThis insert is suited for turning, facing, and boring operations on steel (ISO P workpiece material) and cast iron (ISO K workpiece material). The LF chip breaker geometry is optimized for finishing and light machining passes, making it appropriate for applications where surface finish and dimensional accuracy are priorities. The positive side clearance (clearance code P) and neutral insert hand allow fitment in a range of CPMT-style screw-on toolholders. Maximum depth of cut is 1.25 mm (0.0500 inches). The KCK20 grade is characterized by high wear resistance in steel applications and moderate wear resistance combined with toughness in cast iron applications.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eMultilayer PVD AlTiN\/AlCrN coating (KCK20 grade) for high wear resistance on steel and cast iron\u003c\/li\u003e\n\u003cli\u003e80-degree diamond insert shape (CPMT style) with positive rake angle and honed cutting edge\u003c\/li\u003e\n\u003cli\u003eLF chip breaker designed for finishing and light machining operations\u003c\/li\u003e\n\u003cli\u003eScrew-on insert holding method with neutral insert hand\u003c\/li\u003e\n\u003cli\u003e2 cutting edges per insert; maximum depth of cut 1.25 mm (0.0500 inches)\u003c\/li\u003e\n\u003cli\u003eMeets ANSI and ISO standards; ANSI code CPMT3251, ISO code CPMT09T304\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in CPMT-style screw-on turning toolholders compatible with ANSI insert code CPMT3251 and ISO insert code CPMT09T304.

Ensure the machine spindle is fully stopped and the toolholder is properly secured before seating or replacing the insert. Use the correct torx or hex key to the toolholder manufacturer's specified insert screw torque when fastening the screw-on retention screw. Inspect the insert pocket and locating surfaces for chips or debris before seating to ensure proper insert contact and repeatability.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eANSI Insert Code\u003c\/strong\u003e: CPMT3251\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eISO Insert Code\u003c\/strong\u003e: CPMT09T304\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: CPMT\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: KCK20\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Material\u003c\/strong\u003e: Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: AlTiN \/ AlCrN Multilayer PVD\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\u003eInscribed Circle\u003c\/strong\u003e: 3\/8 inch (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 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\u003eIncluded Angle\u003c\/strong\u003e: 80 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRelief Angle\u003c\/strong\u003e: 11 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRake Angle\u003c\/strong\u003e: 5 degrees (Positive)\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\u003eMaximum Depth of Cut\u003c\/strong\u003e: 1.25 mm (0.0500 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHole Diameter\u003c\/strong\u003e: 4.40 mm (0.1732 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 (P), Cast Iron (K)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating Process\u003c\/strong\u003e: PVD\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: 0.1 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: 3755484\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51740732719410,"sku":"3755484","price":211.78,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/f354c6012c17370fea5554f18f695ab9_90f25051-0311-4503-83d5-76699bb30f74.jpg?v=1788827026","url":"https:\/\/voomisupply.com\/products\/kennametal-3755484-cpmt3251lf-kck20-turning-insert","provider":"Voomi Supply","version":"1.0","type":"link"}
