It carries the A2022R16CF00 form designation, indicating a 2.2 mm cutting width, a 16-degree right-hand lead angle, and a CF chipbreaker geometry. The insert is manufactured from carbide with a KCU25 grade and an AlTiN coating applied via PVD process, providing wear resistance and thermal stability at elevated cutting speeds. It uses a clamp-style holding method and is intended for single-end use. Machinists and CNC setup techs working in production turning environments install this insert as a direct replacement or standard consumable.\u003c\/p\u003e\n\u003cp\u003eThis insert is suited for parting, grooving, and cutoff applications in general-purpose turning. The CF chipbreaker geometry assists with chip control in a range of workpiece materials. The KCU25 carbide grade with AlTiN PVD coating is appropriate for machining steel, cast iron, and similar materials at moderate to high cutting speeds. The right-hand lead angle orientation and clamp-style seat make it compatible with A2-series toolholders that accept size 2 insert seats. This part is sold individually but carries a minimum order quantity of 10 units.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e2.2 mm cutting width for precise parting and grooving operations\u003c\/li\u003e\n  \u003cli\u003eKCU25 carbide grade with AlTiN PVD coating for wear and heat resistance\u003c\/li\u003e\n  \u003cli\u003eCF chipbreaker geometry for controlled chip evacuation\u003c\/li\u003e\n  \u003cli\u003e16-degree right-hand lead angle, A2 series designation\u003c\/li\u003e\n  \u003cli\u003eClamp-style insert holding method, single-end configuration\u003c\/li\u003e\n  \u003cli\u003eSize 2 insert seat, compatible with A2-series toolholders\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with A2-series clamp-style cutoff and grooving toolholders that accept a size 2 insert seat and a right-hand lead angle configuration.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by qualified machinists or CNC tooling technicians. Power down and lock out the machine spindle before seating or removing inserts. Use the appropriate torx or hex key to secure the clamp to the specified feel of resistance — do not over-torque the clamp screw. Inspect the insert seat for chips or debris before seating a new insert to ensure proper contact and runout.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: A2\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: Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: C2, C6\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: 2.20 mm (0.0866 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 10.50 mm (0.4134 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Height\u003c\/strong\u003e: 4.77 mm (0.1878 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLead Angle\u003c\/strong\u003e: 16 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLead Angle Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRelief Angle\u003c\/strong\u003e: 2.00 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.0000 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChipbreaker\u003c\/strong\u003e: CF\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Seat Size\u003c\/strong\u003e: 2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFull Radius\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSingle or Double End\u003c\/strong\u003e: Single\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Holding Method\u003c\/strong\u003e: Clamp\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.003 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: 4111090\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51732407517490,"sku":"4111090","price":337.06,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/2b6b52b14404e0273158bde3c7cbb114.jpg?v=1788742480","url":"https:\/\/voomisupply.com\/products\/kennametal-4111090-cutoff-insert-kcu25-carbide-2-2mm","provider":"Voomi Supply","version":"1.0","type":"link"}
