Manufactured in the Top Notch series, it features a KCU25 grade carbide substrate with a PVD-applied AlTiN coating for extended tool life under elevated cutting temperatures. The insert has a 2.39 mm cutting width, a maximum depth of cut of 6.35 mm, and a left-hand orientation. The K chip breaker geometry promotes controlled chip evacuation in medium to finishing cut applications. Machinists and CNC operators working with steel, stainless, and cast iron will find this insert suited for interrupted and continuous grooving passes where dimensional accuracy is critical.\u003c\/p\u003e\n\u003cp\u003eThis insert is intended for use in Top Notch series clamp-style grooving toolholders on CNC turning equipment. It is suited for light to medium-duty grooving in materials classified under C2 and C6 material grades, including carbon steels and cast irons. The 55-degree included angle and 0.19 mm corner radius support clean groove profiles with tight tolerances. Typical applications include snap ring grooves, undercuts, and face grooving on turned components in general machining and production environments.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eKCU25 solid carbide grade with PVD AlTiN coating for heat and wear resistance\u003c\/li\u003e\n  \u003cli\u003e2.39 mm cutting width with a maximum depth of cut of 6.35 mm\u003c\/li\u003e\n  \u003cli\u003eLeft-hand insert orientation for specific toolholder configurations\u003c\/li\u003e\n  \u003cli\u003eK chip breaker geometry for controlled chip flow in medium to finishing operations\u003c\/li\u003e\n  \u003cli\u003eClamp-style insert holding method compatible with Top Notch series toolholders\u003c\/li\u003e\n  \u003cli\u003e55-degree included angle and 0.19 mm corner radius for accurate groove profiles\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with Top Notch series clamp-style grooving toolholders that accept NGD-style inserts with an insert size designation of 3094.

Ensure the machine spindle is fully stopped and the toolholder is secured in the turret before seating or replacing the insert. Use the appropriate clamp screw torque per the toolholder manufacturer specifications. Inspect the insert seat and clamp for chips or debris before installation to ensure proper seating and prevent insert rocking.\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: KCU25\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: AlTiN\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: 2.39 mm (0.0941 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Depth of Cut\u003c\/strong\u003e: 6.35 mm (0.2500 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Depth of Cut Range\u003c\/strong\u003e: 5.00 mm to 10.00 mm (0.2000 to 0.3000 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Height\u003c\/strong\u003e: 8.74 mm (0.3440 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Width\u003c\/strong\u003e: 4.98 mm (0.196 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\u003eChip Breaker\u003c\/strong\u003e: K\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Size\u003c\/strong\u003e: 3094\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Holding Method\u003c\/strong\u003e: Clamp\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: C2, C6\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: 0.025 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: 4109846\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51743425724722,"sku":"4109846","price":203.43,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/151a037ab6955098b4b259cd4a2559bc.jpg?v=1788846917","url":"https:\/\/voomisupply.com\/products\/kennametal-4109846-grooving-insert-kcu25-solid-carbide-altin","provider":"Voomi Supply","version":"1.0","type":"link"}
