It carries a PVD-applied TiN coating and a KC730 grade designation, placing it in the C2, C3, and C4 material grade range. The insert delivers a 4.8 mm (0.1890 inch) cutting width with a maximum depth of cut of 9.53 mm (0.3752 inch). A positive rake angle of 10 degrees and a K-style chip breaker work together to support controlled chip flow during grooving passes. Installed by machinists and CNC operators, this insert suits production environments where consistent groove geometry is required.\u003c\/p\u003e\u003cp\u003eThe 1114345 is suited for grooving applications in general metalworking and production turning where the Top Notch tooling system is in use. It handles materials within the C2, C3, and C4 grade range, covering a broad spectrum of steels and cast irons. The right-hand orientation and 3-degree lead angle position it for standard external grooving setups. The K chip breaker geometry is optimized for maintaining chip control across the supported depth-of-cut range of 5.00 mm to 10.00 mm.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eKC730 grade solid carbide with PVD TiN coating for wear resistance\u003c\/li\u003e\n\u003cli\u003e4.8 mm cutting width with a maximum depth of cut of 9.53 mm\u003c\/li\u003e\n\u003cli\u003ePositive rake angle (10 degrees) reduces cutting forces during grooving\u003c\/li\u003e\n\u003cli\u003eK-style chip breaker promotes controlled chip evacuation\u003c\/li\u003e\n\u003cli\u003eRight-hand insert orientation with a 3-degree lead angle\u003c\/li\u003e\n\u003cli\u003eCorner radius of 0.57 mm (0.0225 inch) for defined groove edge geometry\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 and insert style NGD.

Use the appropriate torx or insert-clamping key specified for the Top Notch toolholder to seat the insert securely without over-torquing the clamp screw. Verify insert orientation and seating before resuming spindle operation. Inspect the insert seat for chips or debris that could affect insert stability and groove accuracy.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: NGD\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: 4189\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Seat Size\u003c\/strong\u003e: 4\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: KC730\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: C2, C3, C4\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\u003eCutting Width\u003c\/strong\u003e: 4.80 mm (0.1890 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Depth of Cut\u003c\/strong\u003e: 9.53 mm (0.3752 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Depth of Cut Range\u003c\/strong\u003e: 5.00 mm to 10.00 mm (0.3000 to 1.0000 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Height\u003c\/strong\u003e: 0.4530 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.57 mm (0.0225 inches)\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\u003eLead Angle\u003c\/strong\u003e: 3 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIncluded Angle\u003c\/strong\u003e: 55 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChip Breaker\u003c\/strong\u003e: K\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Hand\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMeasurement Type\u003c\/strong\u003e: Metric\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFull Radius\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMulti-use Tool\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.0534 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: 1114345\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51748775395634,"sku":"1114345","price":254.97,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/27854289acb5158cfedaec80cbfd2bf8.jpg?v=1788898187","url":"https:\/\/voomisupply.com\/products\/kennametal-1114345-grooving-insert-kc730-carbide-tin","provider":"Voomi Supply","version":"1.0","type":"link"}
