It carries the KCU25 manufacturer grade and features a PVD-applied AlTiN coating for thermal resistance and extended tool life in interrupted cuts and general-purpose turning. The insert is left-hand oriented with a 3.18 mm cutting width and a maximum depth of cut of 6.35 mm. Corner radius measures 0.19 mm, and the rake angle is 12 degrees. It belongs to the Top Notch series and is held in place by a clamp-style insert holding method. Machinists and tooling specialists install this insert in compatible Top Notch grooving toolholders.\u003c\/p\u003e\n\u003cp\u003eThis insert is suited for grooving, profiling, and light turning applications on CNC turning centers in both production and job-shop environments. The NFD insert style with K chip breaker geometry is optimized for metric-measurement setups. The 55-degree included angle and 12-degree rake angle make it appropriate for medium-duty grooving in steel and alloy materials. The KCU25 carbide grade with AlTiN finish performs well in dry or minimal-lubrication cutting conditions. This insert is sold individually, with a minimum order quantity of 5 units per transaction.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide construction with PVD AlTiN coating for heat and wear resistance\u003c\/li\u003e\n  \u003cli\u003e3.18 mm cutting width with a maximum depth of cut of 6.35 mm\u003c\/li\u003e\n  \u003cli\u003eLeft-hand insert orientation for correct engagement in Top Notch toolholders\u003c\/li\u003e\n  \u003cli\u003eK chip breaker geometry with 12-degree rake angle for controlled chip formation\u003c\/li\u003e\n  \u003cli\u003e0.19 mm corner radius for reduced stress concentration at the groove bottom\u003c\/li\u003e\n  \u003cli\u003eClamp-type insert holding for rigid, repeatable seating in the toolholder\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 NFD-style inserts in size 3125.

Ensure the machine spindle is fully stopped and the toolholder is secured before seating or removing the insert. Use the correct clamping screw torque as specified by the toolholder manufacturer — do not estimate. Inspect the insert seat and clamping mechanism for wear or debris before installing a new insert to ensure proper seating and cutting edge engagement.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: NFD\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: 3.18 mm (0.1252 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\u003eCorner Radius\u003c\/strong\u003e: 0.19 mm (0.0075 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\u003eIncluded Angle\u003c\/strong\u003e: 55 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRake Angle\u003c\/strong\u003e: 12 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: 3125\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\u003eMulti-use Tool\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.001 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23242105\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\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: 4109651\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51732426359090,"sku":"4109651","price":172.03,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/38958047b334f60dc80e624dd686e88b.jpg?v=1788742668","url":"https:\/\/voomisupply.com\/products\/kennametal-4109651-grooving-insert-nfd3125k-kcu25-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
