Built to the NGD insert style and manufactured in grade K313, this uncoated bright-finish insert delivers consistent performance in demanding cutting applications. The left-hand orientation and positive rake angle of 10 degrees promote clean chip flow and reduce cutting forces during the grooving pass. A corner radius of 0.19 mm and a cutting width of 3.18 mm (0.1252 inches) make it well suited for controlled, repeatable groove profiles. Licensed machinists and CNC operators in production and job-shop environments will recognize this insert as part of the established Top Notch series.\u003c\/p\u003e\u003cp\u003eThis insert is intended for use in Top Notch series grooving toolholders and blade systems. It is suited for grooving operations where maximum depth of cut ranges from 5.00 mm to 10.00 mm (roughly 0.200 to 0.300 inches), with a nominal maximum depth of 6.35 mm (0.250 inches). The 55-degree included angle and K chip breaker geometry are optimized for metric-dimensioned applications on ferrous and non-ferrous workpiece materials classified in the C3 and C4 material grade ranges. No coating is applied, keeping the insert in its bright, as-ground condition for applications where coating is not required or preferred.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eInsert style NGD in grade K313, uncoated bright finish\u003c\/li\u003e\n\u003cli\u003eLeft-hand cutting orientation with positive 10-degree rake angle\u003c\/li\u003e\n\u003cli\u003eCutting width of 3.18 mm (0.1252 inches) for precise groove sizing\u003c\/li\u003e\n\u003cli\u003eMaximum depth of cut 6.35 mm (0.250 inches); operational range 5.00 mm to 10.00 mm\u003c\/li\u003e\n\u003cli\u003eK chip breaker geometry with 55-degree included angle for controlled chip formation\u003c\/li\u003e\n\u003cli\u003eCorner radius of 0.19 mm (0.0075 inches) for defined groove edge geometry\u003c\/li\u003e\n\u003cli\u003ePart of the Top Notch series for broad toolholder compatibility within that system\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with Top Notch series grooving toolholders and blade systems that accept NGD-style inserts in the 3125 insert size.

Use the appropriate Top Notch clamping screw and torx or hex key as specified by the toolholder manufacturer. Inspect the insert pocket and clamping mechanism for chips or debris before seating the insert. Never overtighten the clamping screw, as carbide inserts are brittle and can crack under uneven clamping load.\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\u003eManufacturer Grade\u003c\/strong\u003e: K313\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: Bright\/Uncoated\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: 3.18 mm (0.1252 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Depth of Cut\u003c\/strong\u003e: 6.35 mm (0.250 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Depth of Cut Range\u003c\/strong\u003e: 5.00 mm to 10.00 mm (0.200 to 0.300 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.19 mm (0.0075 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRake Angle\u003c\/strong\u003e: 10 degrees (Positive)\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 Size\u003c\/strong\u003e: 3125\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: C3, C4\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLead Angle\u003c\/strong\u003e: 3 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: Top Notch\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\u003eUNSPSC Code\u003c\/strong\u003e: 23242105\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.0249 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: 1114487\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51744016662834,"sku":"1114487","price":185.08,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/32b7e864a3fb89ac127017b8a3f25e32_40e3d1cb-d80e-48c5-b2cc-78bf20be3a39.jpg?v=1788852970","url":"https:\/\/voomisupply.com\/products\/kennametal-1114487-grooving-insert-ngd3125k-k313-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
