Part of the Top Notch series, this insert features a KCU25 carbide grade with a PVD-applied AlTiN coating, making it well-suited for interrupted cuts and materials that generate high cutting temperatures. The cutting width measures 1.58 mm (0.0622 inches) and the maximum depth of cut is 2.79 mm (0.1098 inches). The K chip breaker geometry and 0.19 mm corner radius support controlled chip formation during precision grooving. This insert is installed and replaced by machinists and CNC tooling technicians in production and job-shop environments.\u003c\/p\u003e\u003cp\u003eThis insert is used in external grooving applications on lathes and turning centers where precise groove width and depth control are required. The right-hand orientation suits standard spindle configurations. The Top Notch series uses a clamp-style insert holding method, so this insert seats into compatible Top Notch toolholders. It is appropriate for metric-based setups and is sized at insert size 2062. Material grade classifications C2 and C6 indicate suitability for a range of ferrous and non-ferrous workpiece materials at moderate to high cutting speeds.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eKCU25 solid carbide grade with PVD AlTiN coating for heat resistance and extended tool life\u003c\/li\u003e\n\u003cli\u003e1.58 mm cutting width (0.0622 inches) for tight-tolerance groove applications\u003c\/li\u003e\n\u003cli\u003eMaximum depth of cut 2.79 mm (0.1098 inches), rated range 2.00 to 3.00 mm\u003c\/li\u003e\n\u003cli\u003eK chip breaker geometry promotes controlled chip evacuation during grooving\u003c\/li\u003e\n\u003cli\u003eRight-hand cut orientation for standard lathe setups\u003c\/li\u003e\n\u003cli\u003eClamp-style insert holding for secure seating in Top Notch series toolholders\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with Top Notch series clamp-style toolholders that accept NG-style inserts at insert size 2062.

Use the correct clamp screw torque as specified in the Top Notch toolholder documentation  -  do not rely on feel alone when seating the clamp. Inspect the insert pocket and clamp for wear or debris before seating the new insert. Confirm depth-of-cut programming stays within the 2.00 to 3.00 mm rated range to avoid insert overload.\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\u003eMaterial Grade\u003c\/strong\u003e: C2, C6\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: Right Hand\u003c\/li\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 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\u003eChip Breaker\u003c\/strong\u003e: K\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Size\u003c\/strong\u003e: 2062\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\u003eMulti-use Tool\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\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: 0.05 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: 4109676\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51743241830706,"sku":"4109676","price":228.32,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/aa1cdb7b9bd324ae5abde4ca5018118e.jpg?v=1788844405","url":"https:\/\/voomisupply.com\/products\/kennametal-4109676-grooving-insert-kcu25-top-notch-1-58mm","provider":"Voomi Supply","version":"1.0","type":"link"}
