It carries the KCU25 manufacturer grade with a PVD-applied AlTiN coating for extended tool life in demanding materials. The insert features a 3.00 mm cutting width and a maximum depth of cut of 3.81 mm, making it well suited for precision groove profiles in medium to finish-cut applications. A left-hand orientation and NG insert style position this insert for use with compatible Top Notch clamp-style toolholders. Installation and use are typically performed by skilled machinists and CNC turning technicians.\u003c\/p\u003e\u003cp\u003eThis insert is intended for grooving applications where consistent groove width and depth control are required. The KCU25 grade with AlTiN coating performs well in steel, alloy steel, and other materials where heat resistance and edge durability are priorities. The K-style chip breaker aids in chip control during interrupted or continuous groove cuts. This is a left-hand insert, meaning it is configured for right-to-left feed direction. The Top Notch series uses a mechanical clamp holding method for secure seating in the toolholder pocket.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eKCU25 solid carbide grade with PVD AlTiN coating for heat and wear resistance\u003c\/li\u003e\n\u003cli\u003e3.00 mm cutting width with a maximum depth of cut of 3.81 mm\u003c\/li\u003e\n\u003cli\u003eLeft-hand insert orientation for right-to-left feed direction\u003c\/li\u003e\n\u003cli\u003eK-style chip breaker for controlled chip formation\u003c\/li\u003e\n\u003cli\u003eClamp-style insert holding method compatible with Top Notch series toolholders\u003c\/li\u003e\n\u003cli\u003eCorner radius of 0.19 mm for defined groove edge geometry\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with Top Notch series clamp-style grooving toolholders that accept NG insert style with a size 4 insert seat.

Before changing inserts, ensure the machine is powered down, the spindle is stopped, and all motion has ceased. Use appropriate insert removal tools to avoid contact with cutting edges. Verify correct insert hand orientation and chip breaker selection before resuming cuts, and confirm the insert is fully seated and the clamp is secured before operation.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\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\u003eInsert Hand\u003c\/strong\u003e: Left Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Width\u003c\/strong\u003e: 3.00 mm (0.1181 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\u003eCutting Height\u003c\/strong\u003e: 11.51 mm (0.4530 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Width\u003c\/strong\u003e: 6.50 mm (0.256 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 Seat Size\u003c\/strong\u003e: 4\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Size\u003c\/strong\u003e: 4M300\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\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\u003ePackage Dimensions\u003c\/strong\u003e: 14.8 inches length, 7.1 inches width, 2.7 inches height\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.055 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: 4109793\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51730505597234,"sku":"4109793","price":347.49,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/13c85eec7dd645ea75967cf6b286c4d8.jpg?v=1788718655","url":"https:\/\/voomisupply.com\/products\/kennametal-4109793-grooving-insert-kcu25-altin-left-hand","provider":"Voomi Supply","version":"1.0","type":"link"}
