Coated with TiN via a PVD process, this left-hand insert carries a KC730 grade designation and delivers a 0.79 mm cutting width with a maximum depth of cut of 1.27 mm. The positive rake geometry and 10-degree rake angle promote clean chip formation and reduced cutting forces. Machinists and toolroom professionals install this insert in compatible Top Notch toolholders for high-precision grooving applications.\u003c\/p\u003e\u003cp\u003eThis insert is suited for grooving operations on a range of workpiece materials corresponding to material grades C2, C3, and C4, covering cast iron, non-ferrous metals, and certain non-metallic materials. The K-style chip breaker geometry manages chip control in shallow-to-moderate depth passes. With an included angle of 55 degrees and a 3-degree lead angle, the insert is appropriate for light to medium grooving on small-diameter features where tight tolerances are required. The insert size designation is 2031, consistent with the Top Notch NG-style platform.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide construction with KC730 grade for wear resistance in grooving applications\u003c\/li\u003e\n\u003cli\u003eTiN coating applied via PVD process for improved surface hardness and tool life\u003c\/li\u003e\n\u003cli\u003e0.79 mm cutting width for narrow, precise grooves\u003c\/li\u003e\n\u003cli\u003eMaximum depth of cut of 1.27 mm, suitable for shallow groove profiles\u003c\/li\u003e\n\u003cli\u003ePositive rake angle (10 degrees) reduces cutting forces and supports clean chip evacuation\u003c\/li\u003e\n\u003cli\u003eK-style chip breaker aids chip control in short, controlled passes\u003c\/li\u003e\n\u003cli\u003eLeft-hand orientation for specific toolholder and setup configurations\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with Top Notch series NG-style toolholders that accept the 2031 insert size.

Power down and lock out the machine spindle before seating or removing inserts. Use the appropriate torque wrench or insert-seating tool as specified by the toolholder manufacturer — do not overtighten the clamping screw. Inspect the insert pocket for debris or wear before seating a new insert to ensure proper contact and tool life.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: NG\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Size\u003c\/strong\u003e: 2031\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\u003eMaterial\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: 0.79 mm (0.0311 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Depth of Cut\u003c\/strong\u003e: 1.27 mm (0.0500 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.09 mm (0.0035 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\u003eMaterial Grade\u003c\/strong\u003e: C2, C3, C4\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Depth of Cut Range\u003c\/strong\u003e: 0.00 to 2.00 mm (0.0000 to 0.0750 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFull Radius\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.0055 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: 1114303\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51754616979762,"sku":"1114303","price":242.58,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d8a4f8401b018bb0c1f5196af72b0ed0.jpg?v=1788947153","url":"https:\/\/voomisupply.com\/products\/kennametal-1114303-grooving-insert-ng2031k-kc730-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
