Designated grade KCU25 with a PVD-applied AlTiN coating, this insert delivers strong wear resistance and thermal stability in demanding cutting environments. It carries a 2.39 mm cutting width and a maximum depth of cut of 2.79 mm, making it suited for shallow-to-medium groove profiles. The insert uses a clamp-style holding method and is configured for right-hand cutting. Machinists and tool-room technicians working on production turning applications install and index this insert during scheduled tooling maintenance.\u003c\/p\u003e\n\u003cp\u003eThis insert is used in external grooving and form-turning operations on metal workpieces where controlled groove width and depth are critical. The Top Notch series is a common tooling platform found in production and job-shop turning environments across aerospace, automotive, and general metalworking applications. With a 55-degree included angle and a 0.19 mm corner radius, the insert geometry supports clean groove entry and controlled chip formation. The K chip breaker configuration aids in breaking chips on materials where long stringy chips would otherwise interfere with the cut. It is sold individually but requires a minimum order quantity of 5 units per transaction.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eKCU25 carbide grade with PVD AlTiN coating for wear and heat resistance\u003c\/li\u003e\n  \u003cli\u003e2.39 mm cutting width with maximum depth of cut of 2.79 mm\u003c\/li\u003e\n  \u003cli\u003eRight-hand insert orientation for standard external grooving setups\u003c\/li\u003e\n  \u003cli\u003eK chip breaker geometry for controlled chip formation\u003c\/li\u003e\n  \u003cli\u003e0.19 mm corner radius for defined groove edge profiles\u003c\/li\u003e\n  \u003cli\u003eClamp-style insert holding method for secure, repeatable seating\u003c\/li\u003e\n  \u003cli\u003eTop Notch series platform for broad toolholder compatibility within the series\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in Top Notch series grooving toolholders that accept NG-style inserts with insert size 2094.

Use the appropriate torque wrench and clamp screw specified by the toolholder manufacturer — do not over-tighten the clamp screw, as this can crack the carbide. Inspect the toolholder pocket and clamp for debris or wear before seating the new insert. Verify insert orientation and seating before resuming cutting operations.\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\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\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: 2.79 mm (0.1098 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Depth of Cut Range\u003c\/strong\u003e: 2.00 to 3.00 mm (0.1000 to 0.1500 inches)\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 Size\u003c\/strong\u003e: 2094\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Hand\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChip Breaker\u003c\/strong\u003e: K\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\u003eMeasurement Type\u003c\/strong\u003e: Metric\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.04 pounds\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: 4109680\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51753851519282,"sku":"4109680","price":255.16,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/304154699dc612b28785b51a8b6f36ab.jpg?v=1788941491","url":"https:\/\/voomisupply.com\/products\/kennametal-4109680-grooving-insert-ng2094k-kcu25-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
