Carrying the manufacturer grade KC5025 with a PVD-applied TiAlN coating, this insert delivers wear resistance and thermal stability during interrupted and continuous grooving cuts. It features a 0.25 inch (6.35 mm) cutting width, a maximum depth of cut of 0.25 inch (6.35 mm), and a positive rake angle of 10 degrees. The K chip breaker geometry promotes controlled chip evacuation in a variety of workpiece materials. Installation is performed by qualified machinists and CNC tooling technicians as part of a Top Notch series toolholder setup.\u003c\/p\u003e\n\u003cp\u003eThis insert is suited for grooving applications in medium to roughing turning operations on materials classified under C2 and C6 material grades. The right-hand orientation makes it appropriate for standard spindle-direction turning setups. The insert size designation 4250 with an insert seat size of 4 places it in a clearly defined toolholder seat category within the Top Notch series. Typical applications include external grooving, parting-adjacent operations, and profile grooving where controlled depth and chip management are priorities on both ferrous and non-ferrous workpieces.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide substrate with PVD TiAlN coating for wear and heat resistance\u003c\/li\u003e\n  \u003cli\u003e0.25 inch (6.35 mm) cutting width and 0.25 inch (6.35 mm) maximum depth of cut\u003c\/li\u003e\n  \u003cli\u003ePositive rake angle (10 degrees) with K chip breaker for effective chip control\u003c\/li\u003e\n  \u003cli\u003eRight-hand insert orientation for standard turning setups\u003c\/li\u003e\n  \u003cli\u003eCorner radius of 0.0225 inch (0.57 mm) for controlled edge definition\u003c\/li\u003e\n  \u003cli\u003ePart of the Top Notch series, compatible with corresponding NG-style insert seats\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with Top Notch series toolholders accepting NG-style inserts with an insert seat size of 4.

Power down and lock out the machine spindle before seating or removing the insert. Ensure the insert pocket and seating surfaces are clean and free of chips or debris before torquing the clamping screw to the toolholder manufacturer's specification. Inspect the insert seat and clamping mechanism for wear before each insert change.\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\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\u003eCutting Width\u003c\/strong\u003e: 0.2500 inch (6.35 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Depth of Cut\u003c\/strong\u003e: 0.2500 inch (6.35 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Depth of Cut Range\u003c\/strong\u003e: 0.2000 to 0.3000 inch (5.00 to 10.00 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.0225 inch (0.57 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Height\u003c\/strong\u003e: 0.4530 inch\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\u003eInsert Hand\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Size\u003c\/strong\u003e: 4250\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Seat Size\u003c\/strong\u003e: 4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: C2, C6\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: Top Notch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFull Radius\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.0551 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: 1818001\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51738523828530,"sku":"1818001","price":344.53,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/a3a305594d6593184e9aab64e1773985.jpg?v=1788800595","url":"https:\/\/voomisupply.com\/products\/kennametal-1818001-grooving-insert-ng4250k-kc5025-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
