It features a KC730 grade carbide substrate with a PVD-applied TiN coating, delivering wear resistance and thermal stability across a range of workpiece materials. The insert has a cutting width of 4.80 mm and supports a maximum depth of cut of 9.53 mm. Left-hand orientation and a positive rake angle of 10 degrees promote clean chip evacuation and reduced cutting forces. Machinists and CNC operators working in production turning environments will find this insert suited to demanding grooving applications.\u003c\/p\u003e\u003cp\u003eThis insert is intended for use in Top Notch series toolholders and grooving systems in metalworking operations. It is suited for turning and grooving of ferrous and non-ferrous materials falling within material grades C2, C3, and C4. Typical applications include external grooving, parting, and profile turning on medium to large workpieces where controlled chip breaking and consistent groove geometry are required. The K-style chip breaker geometry assists in managing chip flow during moderate to deep cuts in the supported depth range of 5.00 mm to 10.00 mm.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eKC730 carbide grade with PVD TiN coating for wear resistance and extended tool life\u003c\/li\u003e\n\u003cli\u003e4.80 mm cutting width with a maximum depth of cut of 9.53 mm\u003c\/li\u003e\n\u003cli\u003eLeft-hand insert orientation for specific toolholder and application compatibility\u003c\/li\u003e\n\u003cli\u003ePositive rake angle of 10 degrees reduces cutting forces and aids chip evacuation\u003c\/li\u003e\n\u003cli\u003eK-style chip breaker geometry for controlled chip formation\u003c\/li\u003e\n\u003cli\u003eCorner radius of 0.57 mm (0.0224 inches) for consistent groove profile\u003c\/li\u003e\n\u003cli\u003eTop Notch series — designed to index precisely in compatible Top Notch toolholders\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in Top Notch series grooving toolholders accepting insert seat size 4 and insert style NFD, with an included angle of 55 degrees.

Power down and lock out the machine spindle before indexing or replacing the insert. Seat the insert firmly in the toolholder pocket and verify clamping torque per the toolholder manufacturer specification before resuming cuts. Inspect the insert seat and clamping screw for wear or debris before each installation to maintain accurate insert positioning.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: NFD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: Top Notch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Hand\u003c\/strong\u003e: Left Hand\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\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\u003eCorner Radius\u003c\/strong\u003e: 0.57 mm (0.0224 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\u003eChip Breaker\u003c\/strong\u003e: K\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Seat Size\u003c\/strong\u003e: 4\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Size\u003c\/strong\u003e: 4189\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\u003eFull Radius\u003c\/strong\u003e: No\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: 0.0509 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: 1112901\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51752762376498,"sku":"1112901","price":254.05,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/8bcfc00ebd5076d5a8cc5aa038f4dee7.jpg?v=1788930158","url":"https:\/\/voomisupply.com\/products\/kennametal-1112901-grooving-insert-nfd4189k-kc730-left-hand","provider":"Voomi Supply","version":"1.0","type":"link"}
