Manufactured to NG2125K geometry in the Top Notch series, it carries a TiAlN coating applied via PVD process, which improves wear resistance and thermal stability during interrupted cuts and continuous grooving passes. The insert provides a cutting width of 3.18 mm (0.1252 inches) and a maximum depth of cut of 2.79 mm (0.1098 inches) with a positive rake angle of 10 degrees and a corner radius of 0.19 mm (0.0075 inches). It is configured for right-hand operation and is sold individually per package with a minimum order quantity of 5 units.\u003c\/p\u003e\n\u003cp\u003eThis insert is suited for external grooving, recessing, and parting applications in production and job-shop turning environments. The KC5025 grade with K chip breaker geometry is appropriate for machining steel and alloy steel workpieces where controlled chip formation and edge stability are required. It fits Top Notch series grooving toolholders that accept the NG2125 insert size. Installation is performed by qualified machinists or CNC lathe operators in industrial and manufacturing settings.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide substrate in manufacturer grade KC5025 with PVD-applied TiAlN coating for thermal and wear resistance\u003c\/li\u003e\n  \u003cli\u003eCutting width of 3.18 mm (0.1252 inches) with maximum depth of cut of 2.79 mm (0.1098 inches)\u003c\/li\u003e\n  \u003cli\u003ePositive rake angle of 10 degrees reduces cutting forces and improves chip evacuation\u003c\/li\u003e\n  \u003cli\u003eK chip breaker geometry promotes controlled chip formation during grooving passes\u003c\/li\u003e\n  \u003cli\u003eCorner radius of 0.19 mm (0.0075 inches) for defined edge geometry on groove walls\u003c\/li\u003e\n  \u003cli\u003eRight-hand configuration; compatible with Top Notch series NG2125 toolholders\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in Top Notch series grooving toolholders accepting NG2125 insert size.

Use the appropriate torque wrench and insert clamping hardware specified for the Top Notch toolholder to seat the insert correctly. Inspect the toolholder pocket for chips or debris before seating a new insert. Do not exceed the maximum depth of cut specification for the insert grade and geometry in use.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: NG\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Size\u003c\/strong\u003e: 2125\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: Top Notch\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\/Finish\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 Hand\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Width\u003c\/strong\u003e: 3.18 mm (0.1252 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Depth of Cut\u003c\/strong\u003e: 2.79 mm (0.1098 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Depth of Cut Range\u003c\/strong\u003e: 2.00 mm to 3.00 mm (0.1000 to 0.1500 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.19 mm (0.0075 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Height\u003c\/strong\u003e: 0.2190 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRake\u003c\/strong\u003e: Positive\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRake Angle\u003c\/strong\u003e: 10 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLead Angle\u003c\/strong\u003e: 3 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eIncluded Angle\u003c\/strong\u003e: 55 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChip Breaker\u003c\/strong\u003e: K\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFull Radius\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: C2, C6\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMeasurement Type\u003c\/strong\u003e: Metric\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.022 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23242105\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\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: 1818073\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51749272977714,"sku":"1818073","price":243.59,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/240db7fc38d88e77dc55bdd5e80ea018.jpg?v=1788903879","url":"https:\/\/voomisupply.com\/products\/kennametal-1818073-grooving-insert-ng2125k-kc5025-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
