It carries the KC730 manufacturer grade with a PVD-applied TiN finish, offering wear resistance suited for interrupted cuts and continuous grooving in steel, cast iron, and similar materials. The insert is left-hand orientation with a 0.125 inch (3.18 mm) cutting width and a maximum depth of cut of 0.250 inch (6.35 mm). A positive rake angle of 10 degrees and the K chip breaker geometry help control chip flow in moderate to high feed-rate applications. Licensed machinists and CNC operators are the primary users of this insert.\u003c\/p\u003e\n\u003cp\u003eThis insert is intended for use in compatible Top Notch series grooving toolholders in production turning environments, both light manufacturing and job-shop settings. The NGD3125K insert style fits standard Top Notch grooving systems where a left-hand cut direction is required. It is applicable to material grades C2, C3, and C4, making it suitable for a range of ferrous and non-ferrous workpiece materials. Typical applications include grooving for snap rings, O-ring grooves, undercuts, and parting-adjacent operations where controlled width and depth repeatability are critical.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide construction with PVD TiN coating for extended wear life\u003c\/li\u003e\n  \u003cli\u003eKC730 grade optimized for grooving in C2, C3, and C4 material classifications\u003c\/li\u003e\n  \u003cli\u003eCutting width of 0.125 inch (3.18 mm) for precise, repeatable groove sizing\u003c\/li\u003e\n  \u003cli\u003eMaximum depth of cut of 0.250 inch (6.35 mm) within a range of 0.200 to 0.300 inch\u003c\/li\u003e\n  \u003cli\u003ePositive rake angle (10 degrees) with K chip breaker for controlled chip evacuation\u003c\/li\u003e\n  \u003cli\u003eCorner radius of 0.0075 inch (0.19 mm) and 55-degree included angle for defined groove geometry\u003c\/li\u003e\n  \u003cli\u003eLeft-hand cut direction for specific toolholder and approach configurations\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with KENNAMETAL Top Notch series grooving toolholders that accept the NGD insert style in left-hand orientation.

Use the appropriate Top Notch toolholder clamping mechanism and follow the toolholder manufacturer torque guidance for the clamp screw. Inspect the insert seat for chips or debris before seating the insert. Verify cut direction and depth-of-cut parameters against the programmed toolpath before resuming operation.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\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\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: 0.1252 inch (3.18 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Depth of Cut\u003c\/strong\u003e: 0.250 inch (6.35 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Depth of Cut Range\u003c\/strong\u003e: 0.200 to 0.300 inch (5.00 to 10.00 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.0075 inch (0.19 mm)\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\u003eIncluded Angle\u003c\/strong\u003e: 55 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\u003eMaterial Grade\u003c\/strong\u003e: C2, C3, C4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Size\u003c\/strong\u003e: 3125\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: 0.0249 pounds\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: 1114339\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51738160529714,"sku":"1114339","price":199.49,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/b80fd3ac553192d6989b2d909a1a3443.jpg?v=1788796512","url":"https:\/\/voomisupply.com\/products\/kennametal-1114339-ngd3125k-kc730-grooving-insert-left-hand","provider":"Voomi Supply","version":"1.0","type":"link"}
