The insert features a TiAlN PVD coating applied over a carbide substrate, delivering moderate wear resistance and toughness across a range of workpiece materials. Key dimensions include a 0.25-inch inscribed circle, a 0.0039-inch corner radius, and an overall insert length of 0.6104 inches (7.75 mm). The 55-degree diamond shape with positive rake and positive side clearance geometry makes this insert well suited for finishing and light machining passes where tight tolerances are required.\u003c\/p\u003e\u003cp\u003eThis insert is intended for use by machinists and CNC operators working with stainless steel, superalloys, titanium, steel, cast iron, aluminum, and other non-ferrous materials. The LF chip breaker geometry targets finishing and light machining applications, where controlled chip flow and surface finish quality are priorities. With two cutting edges per insert and a screw-on holding method, it fits standard DCGT-style toolholders used in production and job-shop environments. The KC5025 grade is rated for moderate wear resistance and toughness across P, M, K, N, and S workpiece material classifications per ISO standard designations.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eKC5025 TiAlN PVD-coated carbide grade with moderate wear resistance and toughness across steel, stainless steel, cast iron, aluminum, and superalloy applications\u003c\/li\u003e\n\u003cli\u003e55-degree diamond (D) insert shape with positive rake angle and positive side clearance for reduced cutting forces in finishing operations\u003c\/li\u003e\n\u003cli\u003eLF chip breaker geometry optimized for finishing and light machining passes\u003c\/li\u003e\n\u003cli\u003eTwo usable cutting edges per insert, screw-on holding method for secure toolholder engagement\u003c\/li\u003e\n\u003cli\u003e0.0039-inch honed corner radius for controlled edge geometry on precision turning operations\u003c\/li\u003e\n\u003cli\u003eConforms to ANSI insert code DCGT21502 and ISO insert code DCGT070201\u003c\/li\u003e\n\u003cli\u003eMulti-use geometry supports turning, facing, boring, back turning, and back boring in a single insert style\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or direct-fit insert for DCGT-style screw-on toolholders accepting a 55-degree diamond insert with a 0.25-inch inscribed circle, conforming to ANSI code DCGT21502 and ISO code DCGT070201.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by qualified machinists or CNC setup technicians. Before changing inserts, ensure the machine spindle is fully stopped and all motion has ceased before accessing the toolholder. Use the appropriate Torx or hex key as specified by the toolholder manufacturer to seat the screw-on clamp screw; do not overtighten, as this can damage the insert seat or the carbide insert body. Verify insert seating and edge orientation before resuming cutting operations.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eANSI Insert Code\u003c\/strong\u003e: DCGT21502\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eISO Insert Code\u003c\/strong\u003e: DCGT070201\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: DCGT\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Shape\u003c\/strong\u003e: D - Diamond (Rhombic) 55 degrees\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\u003eChip Breaker\u003c\/strong\u003e: LF\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChip Breaker Operation\u003c\/strong\u003e: Finishing and Light Machining\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: 0.2500 inches (1\/4 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Length\u003c\/strong\u003e: 0.6104 inches (7.75 mm)\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\u003eCorner Radius\u003c\/strong\u003e: 0.0039 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIncluded Angle\u003c\/strong\u003e: 55 degrees\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\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\u003eCutting Edge Style\u003c\/strong\u003e: Honed\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: 0.0492 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\u003eNumber of Cutting Edges\u003c\/strong\u003e: 2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Materials\u003c\/strong\u003e: Stainless Steel, Superalloys, Titanium, Steel, Cast Iron, Aluminum, Non-Ferrous\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\u003eWeight\u003c\/strong\u003e: 0.022 pounds\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\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: 1866646\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51748775035186,"sku":"1866646","price":203.88,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/ce88b95caae5b7bb8d1043669b4538a4.jpg?v=1788898180","url":"https:\/\/voomisupply.com\/products\/kennametal-1866646-turning-insert-dcgt2150lf-kc5025","provider":"Voomi Supply","version":"1.0","type":"link"}
