Carrying the KC5025 manufacturer grade with a PVD-applied TiAlN coating, this right-hand insert delivers a 3.18 mm (0.1252 inch) cutting width and a maximum depth of cut of 6.35 mm (0.2500 inch). The positive rake geometry and K-style chip breaker work together to control chip flow and reduce cutting forces in steel and difficult-to-machine alloys. Machinists and CNC operators working in production turning environments will find this insert well suited to interrupted and continuous grooving passes.\u003c\/p\u003e\u003cp\u003eThis insert belongs to the Top Notch series, a system designed for secure indexing and repeatable tool positioning in grooving and threading applications. It is appropriate for use on CNC turning centers handling medium to high material grades, consistent with C2 and C6 carbide material classifications. The NFD insert style with a 55-degree included angle and a 3-degree lead angle make it a practical choice for groove profiling where dimensional consistency across production runs is required.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide construction with PVD TiAlN coating for extended tool life in steel and alloy applications\u003c\/li\u003e\n\u003cli\u003e3.18 mm cutting width (0.1252 inch) for consistent groove sizing\u003c\/li\u003e\n\u003cli\u003eMaximum depth of cut 6.35 mm (0.2500 inch); effective range 5.00 mm to 10.00 mm\u003c\/li\u003e\n\u003cli\u003ePositive rake angle of 10 degrees combined with K chip breaker for controlled chip evacuation\u003c\/li\u003e\n\u003cli\u003eCorner radius of 0.19 mm (0.0075 inch) for fine groove geometry\u003c\/li\u003e\n\u003cli\u003eRight-hand orientation; single-use insert — not a multi-use tool\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in Top Notch series grooving toolholders that accept NFD-style inserts. The MSC\/Manufacturer cross-reference number is NFD3125R\/LK.

Power down and lock out the machine spindle before indexing or replacing inserts. Use the recommended torque wrench and clamping screw specified by the toolholder manufacturer — do not over-torque the clamp screw, as this can fracture the insert. Inspect the insert pocket for chips or debris before seating a new insert to ensure proper contact and alignment.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: NFD\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 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Depth of Cut\u003c\/strong\u003e: 6.35 mm (0.2500 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Depth of Cut Range\u003c\/strong\u003e: 5.00 mm to 10.00 mm (0.2000 to 0.3000 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.19 mm (0.0075 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Height\u003c\/strong\u003e: 0.3440 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Size\u003c\/strong\u003e: 3125\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIncluded Angle\u003c\/strong\u003e: 55 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLead Angle\u003c\/strong\u003e: 3 degrees\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\u003eChip Breaker\u003c\/strong\u003e: K\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: C2, C6\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFull Radius\u003c\/strong\u003e: No\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: 0.0243 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23242105\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: 1817658\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51747464577330,"sku":"1817658","price":199.27,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/a0b313cc6380ff083d4e62d266caf802.jpg?v=1788880590","url":"https:\/\/voomisupply.com\/products\/kennametal-1817658-grooving-insert-kc5025-carbide-tialn","provider":"Voomi Supply","version":"1.0","type":"link"}
