It carries a PVD-applied TiN (titanium nitride) finish and features a left-hand orientation with a 0.25-inch (6.35 mm) cutting width and a maximum depth of cut of 0.50 inches (12.7 mm). The KC730 grade solid carbide substrate suits a broad range of workpiece materials, spanning material grades C2, C3, and C4. Licensed machinists and CNC operators handling production turning work will find this insert suited for tight-tolerance groove profiles where repeatable cutting geometry is required.\u003c\/p\u003e\u003cp\u003eThis insert is intended for grooving applications in metalworking environments, including external grooving on shafts, shoulders, and similar turned features. The full-radius geometry with a corner radius of 0.125 inches (3.18 mm) and a neutral rake angle supports clean, consistent chip formation. The insert seat size is 4, and it is designed for use in compatible Top Notch series toolholders. Typical applications include production turning on both ferrous and non-ferrous materials in job shop and manufacturing settings.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide construction with PVD TiN coating for wear resistance and edge retention\u003c\/li\u003e\n\u003cli\u003eLeft-hand cutting orientation for dedicated left-hand toolholder configurations\u003c\/li\u003e\n\u003cli\u003e0.25-inch (6.35 mm) cutting width with a full radius corner of 0.125 inches (3.18 mm)\u003c\/li\u003e\n\u003cli\u003eMaximum depth of cut 0.50 inches (12.7 mm); depth of cut range 0.30 to 1.00 inches (10.00 to 20.00 mm)\u003c\/li\u003e\n\u003cli\u003eNeutral rake geometry for stable, controlled cutting action\u003c\/li\u003e\n\u003cli\u003eKC730 grade suitable for material grades C2, C3, and C4\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with Top Notch series grooving toolholders accepting insert seat size 4.

Seat the insert fully and squarely in the toolholder pocket before tightening the clamping screw to the toolholder manufacturer's specified torque. Inspect the insert seat and clamp for chips or debris prior to seating. Confirm left-hand orientation matches the toolholder configuration before commencing a cut.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: NRD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: Top Notch\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: Left Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Width\u003c\/strong\u003e: 0.25 inches (6.35 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Depth of Cut\u003c\/strong\u003e: 0.50 inches (12.7 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDepth of Cut Range\u003c\/strong\u003e: 0.30 to 1.00 inches (10.00 to 20.00 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.125 inches (3.18 mm)\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: Neutral\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Size\u003c\/strong\u003e: 4125\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Seat Size\u003c\/strong\u003e: 4\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, C3, C4\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMeasurement Type\u003c\/strong\u003e: Metric\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23242105\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.064 pounds\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: 1114393\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51740863004978,"sku":"1114393","price":254.55,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d27c5cc96e062b074a2062a500a223ca.jpg?v=1788827953","url":"https:\/\/voomisupply.com\/products\/kennametal-1114393-nrd4125-kc730-grooving-insert-left-hand","provider":"Voomi Supply","version":"1.0","type":"link"}
