Designated insert style NG with a KC730 manufacturer grade, it features a PVD-applied TiN coating and a positive rake angle of 10 degrees for reduced cutting forces and improved chip control. The insert delivers a cutting width of 1.83 mm and a maximum depth of cut of 2.39 mm, making it well suited for shallow to medium-depth grooving applications. Right-hand orientation and a K-style chip breaker geometry support consistent chip evacuation during interrupted or continuous cuts. Licensed machinists and CNC operators install and index this insert as part of routine tooling maintenance.\u003c\/p\u003e\n\u003cp\u003eThis insert fits within the Top Notch series tooling system and is intended for grooving and turning applications in materials classified under grades C2, C3, and C4, which typically include cast irons, non-ferrous metals, and non-metallic materials. The 55-degree included angle and 0.19 mm corner radius allow controlled entry into narrow groove profiles. It is used in production and job-shop environments on both horizontal and vertical turning centers where repeatable groove geometry and surface finish are required.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide substrate with KC730 grade for wear resistance in C2, C3, and C4 material classifications\u003c\/li\u003e\n  \u003cli\u003ePVD TiN coating for improved surface lubricity and extended tool life\u003c\/li\u003e\n  \u003cli\u003e1.83 mm cutting width with a maximum depth of cut range of 2.00 to 3.00 mm\u003c\/li\u003e\n  \u003cli\u003ePositive rake angle (10 degrees) reduces cutting forces on the workpiece\u003c\/li\u003e\n  \u003cli\u003eK-style chip breaker geometry promotes reliable chip control and evacuation\u003c\/li\u003e\n  \u003cli\u003eRight-hand insert orientation for standard OD grooving setups\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with Top Notch series grooving toolholders accepting NG-style inserts, size 3072.

Use the appropriate torque wrench and insert-seating tool recommended for the Top Notch toolholder system to avoid insert cracking or improper seating. Inspect the insert pocket and clamping mechanism for wear or debris before seating a new insert. Follow the toolholder manufacturer guidelines for clamping torque to ensure secure retention during cutting.\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\u003eManufacturer Grade\u003c\/strong\u003e: KC730\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: TiN\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: 1.83 mm (0.0720 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\u003eInsert Height\u003c\/strong\u003e: 0.3440 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Size\u003c\/strong\u003e: 3072\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\u003eFull Radius\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: C2, C3, C4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: Top Notch\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: 0.0212 pounds\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: 1114318\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51735003595058,"sku":"1114318","price":257.84,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/8f596419a10662f7e368078e5a793f65.jpg?v=1788769081","url":"https:\/\/voomisupply.com\/products\/kennametal-1114318-grooving-insert-ng3072k-kc730-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
