It carries a multilayer MTCVD coating of TiCN and Al2O3, which builds wear resistance while maintaining toughness across a range of cutting conditions. The insert features an 80-degree diamond (rhombic) shape, a positive rake angle of 15 degrees, and a honed cutting edge for clean, consistent finishes. The FP chip breaker is optimized for finishing operations, making this insert a direct choice when surface finish and dimensional accuracy are the primary objectives. Licensed machinists and CNC operators working in job shops or production environments will recognize this as a standard screw-on style insert.\u003c\/p\u003e\u003cp\u003eThis insert is rated for finishing operations in turning, facing, and boring applications. Its grade characteristics target steel (P) workpiece materials with moderate wear resistance and toughness, and aluminum and non-ferrous (N) materials with moderate to high toughness. The neutral hand orientation and positive side clearance make it adaptable to standard right-hand toolholders configured for CPMT-style inserts. It is equally suited to short-run job work and higher-volume production turning where consistent finish quality matters.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eKCP25 grade with multilayer MTCVD TiCN and Al2O3 coating for wear resistance and toughness\u003c\/li\u003e\n\u003cli\u003e80-degree diamond insert shape (CPMT) with positive rake and positive side clearance\u003c\/li\u003e\n\u003cli\u003eFP chip breaker geometry optimized for finishing cuts in steel and non-ferrous materials\u003c\/li\u003e\n\u003cli\u003eHoned cutting edge style for improved edge stability on light finishing passes\u003c\/li\u003e\n\u003cli\u003eScrew-on insert holding method for secure, repeatable seating in compatible toolholders\u003c\/li\u003e\n\u003cli\u003eTwo cutting edges per insert; neutral hand for flexible toolholder compatibility\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement turning insert for toolholders accepting CPMT-style screw-on inserts per ANSI and ISO standards (ANSI: CPMT21505, ISO: CPMT060202).

Before indexing or replacing an insert, power down the machine spindle and verify the turret is fully stopped. Use the appropriate Torx or hex key to torque the screw per the toolholder manufacturer specification — do not overtighten or substitute fasteners. Inspect the insert seat and clamp pocket for chips or debris before seating the new insert, as contamination can affect insert position and surface finish.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eANSI Insert Code\u003c\/strong\u003e: CPMT21505\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eISO Insert Code\u003c\/strong\u003e: CPMT060202\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: KCP25\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: TiCN and Al2O3 (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 Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 0.2500 inches (1\/4 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Length\u003c\/strong\u003e: 6.45 mm (0.2539 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Thickness\u003c\/strong\u003e: 0.0938 inches (3\/32 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 0.2500 inches (1\/4 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.0079 inches (1\/128 inch)\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: 15 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSide Clearance\u003c\/strong\u003e: Positive\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: FP (Finishing)\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 Hand\u003c\/strong\u003e: Neutral\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Holding Method\u003c\/strong\u003e: Screw-On\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHole Diameter\u003c\/strong\u003e: 0.1102 inches (2.80 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Depth of Cut\u003c\/strong\u003e: 0.0845 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Steel, Cast Iron\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\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\u003ePackage Quantity\u003c\/strong\u003e: 1 insert per package (minimum order quantity: 5)\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: 3769124\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51728547348786,"sku":"3769124","price":186.33,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/ceab44dc84c9d19479517ca6255751a3_f9a6e3f3-01f7-4b45-b320-2f6bf13e97eb.jpg?v=1788693119","url":"https:\/\/voomisupply.com\/products\/kennametal-3769124-cpmt21505fp-kcp25-turning-insert","provider":"Voomi Supply","version":"1.0","type":"link"}
