This left-hand insert carries the NG3156K geometry designation and is coated with TiAlN via a PVD process, providing thermal resistance and extended tool life in steel and cast iron applications. It delivers a cutting width of 3.96 mm (0.1559 inches) and a maximum depth of cut of 3.81 mm (0.1500 inches). The positive rake angle of 10 degrees and a K-style chip breaker promote controlled chip formation and reduced cutting forces. Machining specialists and CNC toolroom technicians specify this insert for demanding grooving work where dimensional consistency is critical.\u003c\/p\u003e\n\u003cp\u003eThis insert belongs to the Top Notch series, a system designed for external grooving, face grooving, and cut-off applications on turning equipment. The NG-style insert seats into compatible Top Notch toolholders. With a manufacturer grade of KC5025 and a material grade rating of C2 and C6, this insert is suited for both general-purpose and higher-speed grooving of ferrous materials. It is a metric-measurement insert sized at 3156, making it appropriate for shops running metric-spec tooling programs in production or job-shop environments.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide substrate with TiAlN PVD coating for heat and wear resistance\u003c\/li\u003e\n  \u003cli\u003eLeft-hand cutting orientation with positive 10-degree rake angle\u003c\/li\u003e\n  \u003cli\u003e3.96 mm cutting width and up to 3.81 mm maximum depth of cut\u003c\/li\u003e\n  \u003cli\u003eK-style chip breaker for controlled chip evacuation during grooving\u003c\/li\u003e\n  \u003cli\u003eCorner radius of 0.19 mm (0.0075 inches) for precise groove geometry\u003c\/li\u003e\n  \u003cli\u003eTop Notch series compatibility for secure, repeatable insert indexing\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with Top Notch series toolholders that accept NG-style grooving inserts in the 3156 insert size.

Power down and lock out the machine before indexing or replacing inserts. Use the appropriate torque wrench and insert clamp hardware specified for the Top Notch toolholder system — do not overtighten the clamping screw by hand. Inspect the insert pocket and clamping mechanism for wear or debris before seating a new insert.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: NG\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\u003eInsert Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: KC5025\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: C2, C6\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: TiAlN\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: 3.96 mm (0.1559 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Depth of Cut\u003c\/strong\u003e: 3.81 mm (0.1500 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Depth of Cut Range\u003c\/strong\u003e: 3.00 mm to 4.00 mm (0.1500 to 0.2000 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\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 Size\u003c\/strong\u003e: 3156\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\u003eWeight\u003c\/strong\u003e: 0.2646 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Order Quantity\u003c\/strong\u003e: 5\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: 1818892\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51728447439154,"sku":"1818892","price":219.98,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/ff5f625a3435aade1b657c42acc94244.jpg?v=1788691332","url":"https:\/\/voomisupply.com\/products\/kennametal-1818892-grooving-insert-ng3156k-kc5025-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
