Built to the NR3078 style in manufacturer grade K68, this uncoated bright-finish insert delivers a 3.96 mm cutting width and a maximum depth of cut of 3.81 mm. The full-radius geometry with a corner radius of 1.98 mm produces a smooth, consistent groove profile. Neutral rake geometry supports stable cutting action across a range of workpiece materials. Installed by machinists and CNC operators in production turning environments, this insert is a direct-fit component for compatible Top Notch toolholders.\u003c\/p\u003e\n\u003cp\u003eThis insert is suited for grooving and profiling operations in metalworking applications where dimensional precision and repeatable performance are required. The K68 carbide grade is appropriate for a range of non-ferrous and cast iron workpiece materials, consistent with material grade C3 classification. The NR style and 3078 insert size make it compatible with standard Top Notch series grooving toolholders designed for that insert family. Typical applications include external groove cutting on turned components in job shop and production machining environments. The insert is sold individually with a minimum order quantity of 5 units.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide construction in manufacturer grade K68, material grade C3\u003c\/li\u003e\n  \u003cli\u003e3.96 mm cutting width for consistent groove sizing\u003c\/li\u003e\n  \u003cli\u003eMaximum depth of cut of 3.81 mm, within a range of 3.00 to 4.00 mm\u003c\/li\u003e\n  \u003cli\u003eFull radius geometry with 1.98 mm corner radius for smooth groove profiles\u003c\/li\u003e\n  \u003cli\u003eBright uncoated finish suitable for applications where coating is not required\u003c\/li\u003e\n  \u003cli\u003eNeutral rake angle for balanced cutting forces and versatile material compatibility\u003c\/li\u003e\n  \u003cli\u003eRight-hand insert orientation for standard lathe turning setups\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with Kennametal Top Notch series toolholders accepting the NR3078 insert style.

Ensure the machine is powered down and all axes are locked before changing inserts. Seat the insert fully into the toolholder pocket and verify clamping torque with the toolholder manufacturer specifications. Inspect the insert seat and clamping screw for wear or debris before installation to ensure proper seating and runout control.\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: 3078\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: K68\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: C3\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: Bright \/ Uncoated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Width\u003c\/strong\u003e: 3.96 mm (0.1559 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\u003eDepth of Cut Range\u003c\/strong\u003e: 3.00 to 4.00 mm (0.1500 to 0.2000 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 1.98 mm (0.0780 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\u003eIncluded Angle\u003c\/strong\u003e: 55 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRake\u003c\/strong\u003e: Neutral\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Hand\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFull Radius\u003c\/strong\u003e: Yes\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: 0.0236 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1 (minimum order quantity: 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: 1113524\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51744422920498,"sku":"1113524","price":233.57,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/b1f37488312768a466acc29477baf326.jpg?v=1788856337","url":"https:\/\/voomisupply.com\/products\/kennametal-1113524-nr3078-k68-carbide-grooving-insert","provider":"Voomi Supply","version":"1.0","type":"link"}
