The insert features a TiAlN coating applied via PVD process, combining moderate wear resistance with toughness for reliable performance across a range of workpiece materials. The 80-degree diamond (rhombic) shape provides a strong cutting geometry, and the 0.0079 inch corner radius supports general-purpose turning, facing, and boring. With a screw-on holding method and positive rake angle of 5 degrees, this insert seats securely in compatible toolholders and delivers consistent cutting performance for production and job-shop environments.\u003c\/p\u003e\u003cp\u003eThis insert is suited for turning, facing, and boring operations in both residential shop and industrial production settings. Primary workpiece materials include stainless steel and superalloys and titanium, with the KC5025 grade also rated for steel, cast iron, and aluminum and non-ferrous materials. The medium chip-breaker geometry handles moderate material removal rates. The neutral hand orientation makes it adaptable to a variety of toolholder configurations. Licensed machinists and CNC operators working in precision machining shops are the typical end users for this insert.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eKC5025 grade with TiAlN PVD coating for moderate wear resistance and toughness across multiple material groups\u003c\/li\u003e\n\u003cli\u003e80-degree diamond insert shape (CPGM) with positive rake and positive side clearance for clean chip formation\u003c\/li\u003e\n\u003cli\u003eNeutral hand orientation compatible with a wide range of screw-on toolholders\u003c\/li\u003e\n\u003cli\u003eMedium chip-breaker geometry suitable for turning, facing, and boring at moderate depths of cut\u003c\/li\u003e\n\u003cli\u003eTwo cutting edges per insert for extended tool life and cost efficiency\u003c\/li\u003e\n\u003cli\u003eHoned cutting edge style reduces microchipping at the cutting edge during entry and exit\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or direct-fit insert for screw-on toolholders accepting CPGM32505 geometry inserts per ANSI and ISO standards (ISO Insert Code: CPGM09T302).

Power down and de-energize the machine spindle before indexing or replacing inserts. Use the manufacturer-specified torque wrench and insert screw to seat the insert correctly in the pocket — do not overtighten by hand. Inspect the insert pocket and seating surface for wear or debris before installing a new insert to ensure proper seating and cutting-edge alignment.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eANSI Insert Code\u003c\/strong\u003e: CPGM32505\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eISO Insert Code\u003c\/strong\u003e: CPGM09T302\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 Degree\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIncluded Angle\u003c\/strong\u003e: 80 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Hand\u003c\/strong\u003e: Neutral\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 0.3750 inches (3\/8 inch)\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: 0.1563 inches (5\/32 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: 5 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSide Clearance\u003c\/strong\u003e: Positive\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRake\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: Common \/ Medium Machining\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Cutting Edges\u003c\/strong\u003e: 2\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: 0.0492 inches (1.25 mm)\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 Materials\u003c\/strong\u003e: Stainless Steel, Superalloys and Titanium, Steel, Cast Iron, Aluminum and Non-Ferrous\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMulti-Use Applications\u003c\/strong\u003e: Turning, Facing, Boring\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: 0.022 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: 1868257\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51744851493170,"sku":"1868257","price":219.71,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/065e01206876a05ebdd41bb1837f270c.jpg?v=1788861545","url":"https:\/\/voomisupply.com\/products\/kennametal-1868257-cpgm32505-kc5025-carbide-turning-insert","provider":"Voomi Supply","version":"1.0","type":"link"}
