Manufactured to the NR3047K style with a KC5025 grade and PVD-applied TiAlN coating, this insert delivers reliable wear resistance in a range of ferrous and non-ferrous materials. The left-hand configuration suits specific tool holder orientations, and the positive rake angle of 10 degrees reduces cutting forces for cleaner groove geometry. The K chip breaker controls chip flow during interrupted and continuous grooving passes.\u003c\/p\u003e\u003cp\u003eThis insert is suited for production turning environments where consistent groove width and depth control are critical. The 2.39 mm cutting width and maximum depth of cut of 3.81 mm make it appropriate for fine to medium grooving work on shafts, bores, and shoulders in both high-volume and job-shop settings. Licensed machinists and CNC operators handling precision turned components are the primary users. It is sold individually but carries a minimum order quantity of 5 units.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide construction with PVD TiAlN coating for elevated heat and wear resistance\u003c\/li\u003e\n\u003cli\u003eKC5025 grade with 10-degree positive rake angle for reduced cutting forces\u003c\/li\u003e\n\u003cli\u003e2.39 mm cutting width with a full radius corner for smooth groove profiles\u003c\/li\u003e\n\u003cli\u003eMaximum depth of cut of 3.81 mm suitable for fine to medium grooving applications\u003c\/li\u003e\n\u003cli\u003eK chip breaker geometry for effective chip control during grooving and parting\u003c\/li\u003e\n\u003cli\u003eLeft-hand insert orientation for compatible Top Notch series tool holders\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in KENNAMETAL Top Notch series tool holders that accept the NR3047K insert style in a left-hand configuration.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified machinist or CNC setup technician with the machine fully powered down and the spindle locked before insert indexing. Use the appropriate torque wrench and seating procedure specified by the tool holder manufacturer to secure the insert without over-torquing the clamping screw. Inspect the insert seat and chip pocket for debris before seating. Do not use damaged or chipped inserts, as they can cause unpredictable tool failure during cutting.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: NR\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: Top Notch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Size\u003c\/strong\u003e: 3047\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\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: Left Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Width\u003c\/strong\u003e: 2.39 mm (0.0941 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Depth of Cut\u003c\/strong\u003e: 3.81 mm (0.1500 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Depth of Cut Range\u003c\/strong\u003e: 3.00 mm to 4.00 mm (0.1500 to 0.2000 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 1.19 mm (0.0469 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFull Radius\u003c\/strong\u003e: Yes\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\u003eIncluded Angle\u003c\/strong\u003e: 55 degrees\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: 0.0183 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: 1808491\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51754836787506,"sku":"1808491","price":280.51,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/95e4b4a8dbb2ac7a2b5db0b068a90116.jpg?v=1788949056","url":"https:\/\/voomisupply.com\/products\/kennametal-1808491-grooving-insert-nr3047k-kc5025-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
