Designated style NR3031K in the Top Notch series, it features a TiAlN coating applied via PVD process, delivering wear resistance and thermal stability at elevated cutting speeds. The insert is left-hand oriented with a 1.58 mm cutting width, a maximum depth of cut of 2.39 mm, and a full corner radius of 0.79 mm. A positive rake angle of 10 degrees and K-style chip breaker geometry promote controlled chip evacuation in a range of workpiece materials. This insert is installed by machinists and CNC operators in production turning environments.\u003c\/p\u003e\n\u003cp\u003eThis insert suits metric grooving applications on lathes and turning centers where tight groove widths and controlled depths are required. The Top Notch series tooling system is common in production shops running medium to high-volume turning operations. The insert size designation is 3031 and it is rated for a maximum depth of cut range of 2.00 mm to 3.00 mm, making it appropriate for shallow to moderate-depth external or face grooving passes. Material grades C2 and C6 indicate suitability for a range of ferrous and non-ferrous machining applications.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide substrate with TiAlN PVD coating for wear and heat resistance\u003c\/li\u003e\n  \u003cli\u003eLeft-hand insert orientation for designated toolholder configurations\u003c\/li\u003e\n  \u003cli\u003e1.58 mm cutting width with full corner radius of 0.79 mm for consistent groove geometry\u003c\/li\u003e\n  \u003cli\u003ePositive 10-degree rake angle reduces cutting forces and improves chip flow\u003c\/li\u003e\n  \u003cli\u003eK chip breaker style promotes reliable chip breaking in turning applications\u003c\/li\u003e\n  \u003cli\u003eManufacturer grade KC5025 suited for a broad range of workpiece materials\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with KENNAMETAL Top Notch series toolholders that accept NR-style grooving inserts in size 3031.

Power down and lock out the machine spindle before changing inserts. Use the correct torque wrench and insert clamp per the toolholder manufacturer guidelines — do not overtighten the clamp screw with standard hand tools. Inspect the insert pocket and clamp for damage or debris before seating the new insert to ensure proper seating and safe operation.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\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: 3031\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: Left Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Width\u003c\/strong\u003e: 1.58 mm (0.0622 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 mm to 3.00 mm (0.0750 to 0.1000 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.79 mm (0.0311 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\u003eMaterial Grade\u003c\/strong\u003e: C2, C6\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: 0.0046 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Order Quantity\u003c\/strong\u003e: 5\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: 1818459\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51737093570866,"sku":"1818459","price":253.38,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/3eeb284c38918bba4367702ad9d0ed24.jpg?v=1788784145","url":"https:\/\/voomisupply.com\/products\/kennametal-1818459-grooving-insert-nr3031k-kc5025-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
