It carries the NG3078K insert style designation with a KC5025 manufacturer grade and a PVD-applied TiAlN coating that provides wear and heat resistance at the cutting edge. The insert is left-hand oriented with a 1.98 mm cutting width, a maximum depth of cut of 2.39 mm, and a 0.19 mm corner radius. A positive rake angle of 10 degrees and the K chip breaker geometry help manage chip flow during grooving passes. This insert is installed by CNC machinists and toolroom technicians working with ferrous and non-ferrous workpiece materials.\u003c\/p\u003e\n\u003cp\u003eThis insert fits Top Notch series toolholders configured for NG-style inserts. It is suited for metric-measurement machining applications in production turning environments where consistent groove width and depth control are required. The KC5025 grade with TiAlN coating is a common selection for interrupted cuts and applications demanding edge toughness alongside surface coating protection. The K chip breaker geometry makes it appropriate for moderate chip-load grooving where reliable chip evacuation is a priority.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide construction with PVD TiAlN coating for wear resistance\u003c\/li\u003e\n  \u003cli\u003eLeft-hand insert orientation for dedicated left-hand toolholder setups\u003c\/li\u003e\n  \u003cli\u003e1.98 mm cutting width with a maximum depth of cut of 2.39 mm\u003c\/li\u003e\n  \u003cli\u003ePositive rake angle (10 degrees) reduces cutting forces during grooving\u003c\/li\u003e\n  \u003cli\u003eK chip breaker geometry promotes controlled chip formation and evacuation\u003c\/li\u003e\n  \u003cli\u003eTop Notch series compatibility ensures secure seating in matched toolholders\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in Top Notch series toolholders accepting NG-style inserts.

Before changing inserts, power down the machine and ensure the spindle is fully stopped and locked out per facility lockout\/tagout procedures. Seat the insert fully in the toolholder pocket and torque the clamping screw to the toolholder manufacturer's specification using the correct Torx or hex key. Inspect the insert seat and clamping surfaces for chips or debris before installation to prevent improper seating and premature edge failure.\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\u003eSeries\u003c\/strong\u003e: Top Notch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Hand\u003c\/strong\u003e: Left Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: KC5025\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: C2, C6\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: 1.98 mm (0.0780 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Depth of Cut\u003c\/strong\u003e: 2.39 mm (0.0941 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Depth of Cut Range\u003c\/strong\u003e: 2.00 to 3.00 mm (0.0750 to 0.1000 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\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\u003eInsert Size\u003c\/strong\u003e: 3078\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\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\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: 1818507\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51738648772914,"sku":"1818507","price":254.08,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/5af448dc9b50a1578b73b1a033303821.jpg?v=1788802319","url":"https:\/\/voomisupply.com\/products\/kennametal-1818507-grooving-insert-ng3078k-kc5025-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
