Carrying the manufacturer grade KC5025 with a PVD-applied AlTiN coating, this insert delivers heat and wear resistance suited for interrupted cuts and challenging workpiece materials. It features a 2.5 mm cutting width and a maximum depth of cut of 5.08 mm. The insert style is NGD, belonging to the Top Notch series, and is configured for left-hand cutting. A corner radius of 0.19 mm and a K-style chip breaker contribute to controlled chip evacuation during grooving passes. Installation is performed by a qualified machinist or toolroom technician using a compatible Top Notch clamp-style toolholder.\u003c\/p\u003e\n\u003cp\u003eThis insert is intended for use in metalcutting applications where controlled grooving, undercutting, or parting is required. The metric sizing — insert size 2M250 — fits Top Notch series toolholders designed for that insert class. The KC5025 grade is suited for a broad range of workpiece material grades, including C2 and C6 material classifications. This is a single-insert package with a minimum order quantity of 5 units, making it appropriate for shop stock replenishment or toolcrib inventory for production turning environments.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eKC5025 PVD AlTiN-coated solid carbide grade for extended tool life in demanding grooving applications\u003c\/li\u003e\n  \u003cli\u003e2.5 mm cutting width with a maximum depth of cut of 5.08 mm\u003c\/li\u003e\n  \u003cli\u003eLeft-hand insert orientation for compatible toolholder configurations\u003c\/li\u003e\n  \u003cli\u003eK chip breaker geometry for reliable chip control during grooving passes\u003c\/li\u003e\n  \u003cli\u003eCorner radius of 0.19 mm for precise groove profile finishing\u003c\/li\u003e\n  \u003cli\u003eTop Notch series clamp-held insert — no full radius, 55-degree included angle\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with Top Notch series clamp-style grooving toolholders that accept the NGD insert style in size 2M250.

Seat the insert fully into the Top Notch toolholder pocket and engage the clamp per the toolholder manufacturer torque guidance. Inspect the insert seat and clamp for chips or debris before seating a new insert, as contamination can cause insert rocking and premature failure. Dispose of worn inserts according to local regulations for carbide tooling waste.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: NGD\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: AlTiN\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: Left Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Width\u003c\/strong\u003e: 2.5 mm (0.0984 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Depth of Cut\u003c\/strong\u003e: 5.08 mm (0.2000 inches)\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 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\u003eCutting Height\u003c\/strong\u003e: 5.56 mm (0.2190 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Width\u003c\/strong\u003e: 3.84 mm (0.151 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Size\u003c\/strong\u003e: 2M250\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChip Breaker\u003c\/strong\u003e: K\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eIncluded Angle\u003c\/strong\u003e: 55 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Holding Method\u003c\/strong\u003e: Clamp\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\u003ePackage Dimensions\u003c\/strong\u003e: 9.5 inches (L) x 2.8 inches (W) x 1.5 inches (H)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.009 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eItem Package Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Order Quantity\u003c\/strong\u003e: 5\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: 3397274\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51736937136434,"sku":"3397274","price":183.72,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/940e9a80c86eabf8ab0126bbb4f8865e.jpg?v=1788782135","url":"https:\/\/voomisupply.com\/products\/kennametal-3397274-grooving-insert-kc5025-altin-2-5mm","provider":"Voomi Supply","version":"1.0","type":"link"}
