Built to the Top Notch series standard, this left-hand insert features an AlTiN coating applied via PVD process, which improves heat resistance and tool life in dry or semi-dry cutting environments. The insert carries manufacturer grade KCU25 and is sized at 2062, delivering a cutting width of 1.58 mm and a maximum depth of cut of 2.79 mm. The K-style chip breaker geometry helps manage chip flow in medium-duty grooving applications. Holding is accomplished via clamp method, consistent with Top Notch series toolholders.\u003c\/p\u003e\n\u003cp\u003eThis insert is suited for grooving, profiling, and light turning operations in metalworking environments including job shops and production turning cells. The left-hand designation means it is configured for right-to-left feed direction on the workpiece. With a material grade rating of C2 and C6, it is appropriate for use on a range of ferrous and non-ferrous materials. The AlTiN PVD coating extends tool life when machining harder steels and alloys. Machinists and CNC operators working with medium cutting depths in the 2.00 mm to 3.00 mm range will find this insert fits standard Top Notch series grooving toolholders.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide construction with AlTiN PVD coating for extended wear resistance\u003c\/li\u003e\n  \u003cli\u003eLeft-hand insert orientation for right-to-left feed applications\u003c\/li\u003e\n  \u003cli\u003e1.58 mm cutting width with a maximum depth of cut of 2.79 mm\u003c\/li\u003e\n  \u003cli\u003eK-style chip breaker for controlled chip evacuation in grooving operations\u003c\/li\u003e\n  \u003cli\u003eCorner radius of 0.19 mm for defined edge geometry at groove transitions\u003c\/li\u003e\n  \u003cli\u003eClamp-style holding method compatible with Top Notch series toolholders\u003c\/li\u003e\n  \u003cli\u003e55-degree included angle and full-radius designation of No for precise groove profiling\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with Top Notch series grooving toolholders that accept NG-style, clamp-held inserts at insert size 2062.

Power down the spindle and engage the machine lock before seating or removing inserts. Use the appropriate torque driver for the clamp screw to ensure the insert is fully seated against the pocket without rocking. Verify left-hand orientation against the toolholder designation before beginning a cut to avoid incorrect feed-direction engagement.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Width\u003c\/strong\u003e: 1.58 mm (0.0622 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Depth of Cut\u003c\/strong\u003e: 2.79 mm (0.1098 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Depth of Cut Range\u003c\/strong\u003e: 2.00 mm to 3.00 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Height\u003c\/strong\u003e: 5.56 mm (0.2190 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Width\u003c\/strong\u003e: 3.84 mm (0.151 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\u003eIncluded Angle\u003c\/strong\u003e: 55 degrees\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: KCU25\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: AlTiN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating Process\u003c\/strong\u003e: PVD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChip Breaker\u003c\/strong\u003e: K\u003c\/li\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: 2062\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Hand\u003c\/strong\u003e: Left Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Holding Method\u003c\/strong\u003e: Clamp\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFull Radius\u003c\/strong\u003e: No\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\u003eWeight\u003c\/strong\u003e: 0.007 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: 4109674\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51727748956466,"sku":"4109674","price":214.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/e72b7d8eef96e5df32f577fe5886b8e4.jpg?v=1788681664","url":"https:\/\/voomisupply.com\/products\/kennametal-4109674-grooving-insert-kcu25-solid-carbide-left-hand","provider":"Voomi Supply","version":"1.0","type":"link"}
