Part of the Top Notch series, it carries the NR insert style with a KC5010 grade and a PVD-applied TiAlN coating that improves wear resistance and tool life in demanding cutting conditions. The insert is left-hand oriented with a 1.00 mm cutting width and a maximum depth of cut of 1.27 mm. The full-radius geometry and neutral rake angle make it well suited for finishing passes and tight-tolerance groove profiles in steel and cast iron workpiece materials per the C3 and C4 material grades.\u003c\/p\u003e\u003cp\u003eThis insert is applied in metric-dimensioned grooving applications on production turning equipment. It is intended for use by machinists and CNC operators running high-precision parts where consistent groove width and depth control are critical. The 1.00 mm cutting width and 1.27 mm maximum depth of cut target narrow groove profiles common in hydraulic fittings, shaft retaining ring grooves, and similar component features. It is not a multi-use tool and is rated for a single insert style and seat configuration within the Top Notch toolholder system.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide construction with PVD TiAlN coating for extended wear life\u003c\/li\u003e\n\u003cli\u003e1.00 mm cutting width for narrow, precise groove profiles\u003c\/li\u003e\n\u003cli\u003eMaximum depth of cut of 1.27 mm suitable for shallow retaining and snap-ring grooves\u003c\/li\u003e\n\u003cli\u003eFull radius geometry with neutral rake for consistent finishing results\u003c\/li\u003e\n\u003cli\u003eLeft-hand insert orientation for correct seating in compatible Top Notch toolholders\u003c\/li\u003e\n\u003cli\u003eKC5010 grade rated for C3 and C4 material groups including steel and cast iron\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in Top Notch series grooving toolholders that accept the NR2M050 insert size and left-hand seat configuration.

Use the correct torque wrench and seating tool specified for Top Notch clamping systems to avoid insert rocking or improper seating. Inspect the toolholder pocket for chips or wear before installing a new insert. Do not exceed the rated maximum depth of cut of 1.27 mm in a single pass.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: NR\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: KC5010\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: C3, C4\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: TiAlN\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: 1.00 mm (0.0394 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\u003eMaximum Depth of Cut Range\u003c\/strong\u003e: 0.00 mm to 2.00 mm (0.0000 to 0.0750 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Size\u003c\/strong\u003e: 2M050\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFull Radius\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRake\u003c\/strong\u003e: Neutral\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIncluded Angle\u003c\/strong\u003e: 55 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMeasurement Type\u003c\/strong\u003e: Metric\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMulti-use Tool\u003c\/strong\u003e: No\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\u003eWeight\u003c\/strong\u003e: 0.015 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: 3387910\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51752547221810,"sku":"3387910","price":245.21,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/fe961e6cef2a2737e2711e30c73c4349.jpg?v=1788929039","url":"https:\/\/voomisupply.com\/products\/kennametal-3387910-grooving-insert-nr2m050-kc5010-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
